    Back pain is one of the most common causes of discomfort when cycling so in this video we’re going to cover some simple bike fit tips that are almost guaranteed to alleviate it to do this we’ve called in the services of the experts expert Phil Bert formerly the

    Physio to British cycling in team Sky he’s now applying all that knowledge and experience into bike fit and ergonomics firstly let’s cover some basic potentials of course I think it’s important that people recognize whether they’re taking their back problem onto the bike and then experiencing on the bike or whether cycling itself is

    Causing the back pain that makes sense and that that’s only important to work out in that you could be blaming cycling and all your position equipment and actually it’s nothing to do with that it’s you you have actually something going on with yourself and that’s easy

    To recognize if you have your back pain in other areas of your life you know and then you can maybe go into a physio doctor get that worked out if it if the back pain is coming from the cycling position it’s normally something to do with um your position or the equipment

    You’re using if you ask me so um the one thing about cycling is it has as I always say no Ecentric forces so it’s a lot less dangerous than for example running you know and there’s not much shot going for your back but there is a positional loading you know so your your

    Lumber spine is generally in flection for a long period of time and that’s why for example even people who haven’t got back pathology or back pain normally if you cycle up a very very long Mountain climb even me or you you don’t you’re not surprised that your back’s a little

    Bit sore by the end because it’s just been in one position for a very long time you know so there’s a postural endurance issue there basically I think if you have back pay my rule is you have back paint before two hours I think there’s something not right you or the

    Bike I think you should be out of cycle for two hours relatively enjoying it and not uncomfortable yeah you might be a bit stiff when you get off it but that stiffness should go way very very quickly if I I’m like you if I ride for

    Four or five hours I fully expect to be a bit stiff and sore right here’s the key thing it should be gone the next day so you can ride if it isn’t and it’s carrying on into the next day 24 hours or 48 hours I think that’s when that’s

    Something that that back Pain’s a bit more involved than just riding the bike and what you experience potentially then a few of you could check out now because some back discomfort is normal when you’re pushing yourself but actually I think we would all benefit from paying attention to the next few points whether

    You pass Phil’s test or not before we crack on a quick request from me please if you like videos about bike fit then hit the like button to show us and also we would really appreciate it if you could show your support for gcn by subscribing to the channel if you don’t

    Do so already okay on with a vid so how do we alleviate back pain there well in Phil’s experience most issues arise from muscular pain in the lumber spine so that’s your lower back here and in the simplest terms it’s as a result of bending it for long periods of

    Time the first P of call is as always to check your saddle position now this is the single most important thing to get right because all other bike fit elements are built around having the optimal pedaling position so is it the right height and is it too far back both

    Of these factors could directly or indirectly cause back pain because they also affect the reach and the drop to the handlebars if you need help finding the optimal position then we have a video on that subject and we will link to it in the description now the third

    And in Phil’s eyes most important adjustment you can make to your saddle is the saddle tilt this one really does directly cause back pain so a saddle should as a rule be either flat or pointing slightly nose down if the saddle is pointing up you’ll find

    That your pelvis won’t be able to rotate forwards because it’s BL and uncomfortable and so that means that your lower back has to compensate by bending More with those dialed in now we can look towards the position of the controls as mentioned the primary cause of back pain when cycling specifically lower back pain is stretching too far forwards and too far down potentially both at the same time now at this point

    I’ve got to say that on many top pend new bikes you might find the adjustment at the front end is anything from hard to Impossible now that end of itself is not a bad thing per se as long as you’ve got your optimal cycling position dialed

    Before you buy a new bike and that you thoroughly check that you can get to your optimal cycling position on whatever you’re buying on this Canyon a road I have got some fine tuning I can do to the bar height and also the bar width but to demonstrate more dramatic

    Chang es I’m going to swap to a static bike firstly if you are suffering from lower back pain R cycling try moving your stem up not just a little bit but quite a sizable amount like maybe 4 cm or something now you’ll probably find that on a normal bike and not a static

    Bike that that adjustment is quite hard to make you may not be able to do it in fact so what you can try instead is flipping your stem so you take the handlebars off then you turn the stem the other way up and that will significantly raise your handlebars and

    Also bring them closer to the saddle now some people might not like the look of this setup here but at least you’ll know if it sorts your issue and if it does brilliant if you still really don’t like the look of having a stem pointing up

    The wrong way then bear in mind that Different Bikes naturally have different height front ends some are taller than others although of course that would necess itate a new bike or at the very least a new frame there is one other option which is significantly less

    Expensive we’ll get on to that in just a moment you can also look at bringing your handlebars closer to you as well now this will necessitate buying a shorter stem you’ll need to swap that bit out but you can also at this point look at your handlebars too so the size

    Of them can vary dramatically between models both in terms of the reach so the distance between this B here and your controls and also the drop as well now what you’re looking for is compact handlebars so that’s where the difference between your hand positions is much smaller I’d say that’s an

    Essential for smaller Riders but actually compact handlebars are my go-to as well now while we’re talking handlebars one thing that Phil mentioned which really took me by surprise was handlebar width so wider handle bars effectively increase your reach to them so making your lower back bend more but

    Phil also said that if your handlebars are too wide having your hand splay apart can put pressure on your upper back causing that to hurt after long periods of time in the saddle so it sounds like shoulder width handlebars are making a comeback there are other less obvious but potentially equally

    Significant equipment choices that can potentially alleviate back pain and one of the most beautiful things in any bite fit is to realize that someone’s on too narrow a saddle because it’s the easiest thing in the world to S saddle you know so saddle width is important if what

    Generally find where it’s too narrow people move around all the time feel really uncomfortable and it’s normally the lower back that feels like because they’re just doing so much movement at the at the sitting point on the bike um and my little really easy tip for that it’s not as straightforward as sometimes

    But if you feel like you constantly push yourself backwards on the saddle and then move forwards and push back it normally quite normally will correlate to you not being on the right width support saddle so the right width and if that’s really easy to understand if you

    Haven’t got the right you know W um if your pelvis is not being supported by the saddle then the lower back’s going to get you know you’re gonna have pain so that’s quite an easy one to check you know and yeah the general rule is women

    Have wider hips than men so they tend to like wi the Saddles but that there’s more variation within gender you know so it’s an easy thing to check and there’s some nice online methods of doing it with cboard and Tim foil we have a fancy digital thing here but it’s worth

    Checking out you know a brand with a big range of saddles like Calia who we work with Will typically have different width options so there’s a 130 on my bike currently and I choose to run a 145 so I’m going to swap that over now what else I need to start a crank

    Blink company but um I cannot tell you how many people I’ve seen who whose back pain has been directly related to running two longer cranks but here’s the good news with this right I think we should look at the crank levels more positive it’s because they’re trying to

    Do some amazing things on the bike either distance-wise or speed wise so they have a really good performance position which is normally lower at the front with a very good saddle height for producing power if your crank length is too long this is why the model here is

    Is here your hit flexes come off here and here so the bottom three Lumber vertebrae and to come through to there if you’re closing up your hip too much that’s what you know you get off the bike and you feel like a few minutes it’s a bit stiff it’s because your Hip

    Flex is grabbing on those bottom vertebrae and pulling them down into extension and that the lot and they’re bit jammed up um so I think manipulating crank length if you want if you’re in the category of I don’t want to raise my front end 20 mil because I like looking

    Like I’m a pro cyclist but you have raging back pain my tip to you is okay you drop your crank length because instead of opening you up from the front let’s open you up from underneath so so what does that look like in reality then well potentially dropping 5 mm off your

    Crank length will make a significant difference now you need to put your Saddle Up by the amount that the crank is shorter so if you lose 5 mil off your cranks put your seat up by 5 mil so that will reduce that hip angle and still give you the optimal pedaling position

    For power output final point on a equipment choices is Tire width now this is another one that I hadn’t considered but makes a lot of sense effectively trying to make your bike as comfortable as possible by reducing the vibration coming from the road or the trail now seemingly there are few drawbacks to

    Running wider tires in these more enlightened times so why not max out your tire clearance and see if that can help these ones here are super light super fast Road Tire in a 35 if that’s not going to be comfortable I don’t know what is now one last word

    From Phil a word of warning in fact is not to change everything all at once cuz you won’t then know what has actually solved your back pain plus it’ be really expensive if you suddenly started swapping out all that equipment and also you might then end up compromising your

    Position in other ways Comfort or performance other ways that you wouldn’t have needed to have done so have a plan and stick to it begin with saddle position then look at bar position then other factors like saddle width crank length etc etc one last word for me now

    There is also a training effect here as well Phil’s words muscular endurance and lack of adaptation so if you have suddenly increased the length of your rides or swapped from road to gravel or perhaps flat roads to Alpine passes it might take a little bit of time for the

    Muscles in your back to catch up with these increased demands it’s one of the reasons why people recommend a graduated increase either in training or run finding something that most of us completely ignore until it’s too late and something happens right then huge thanks to Phil for his time and his

    Expert knowledge in today’s video his practice is up in Manchester here in the UK by the way for those of you lucky enough to live within reach but if you would like more of Phil’s Insight in addition to some videos we’ve already created here on gcn then do make sure

    You check out his book that he’s written on the subject which is well worth a read now I would be very interested to hear your thoughts on this video is back pain something that plagues you on the bike have you managed to fix it prior to

    Watching this video and if so what was it that you that you changed that helped that problem out get involved in the comment section down below and also give this video a big thumbs up if you have appreciated Phil’s time and knowledge

    1. I had upper back ache after long rides.
      Combination of adding a spacer on the bars, consciously rotating hips forward a bit, daily hamstring stretching, and practicing riding in the drops on the trainer seems to have solved it 😀.

    2. It depends. In case you haven't changed a thing on your bike, and the problem occurs, it is a matter of muscle dysbalance, and some training – e.g. laying on your back and lifting your a**, so it is in line with your upper legs, and holding for up to 45 sec, min15 times – should help. In case you have a new bike and you were to lazy to note your position (most important the saddle in relation to the bottom bracket), you have to adjust the bike by only changing one thing at a time. But don't exaggerate, don't go to easy, even at higher ages the body is able to adopt to a new position, and always remember: pain is temporarily, glory is forever.

    3. I've been very lucky so far. At 50+ y/o I've covered several thousand KM since I took up cycling a year ago – a mixture of road and off-road (mountain) riding – and no pain so far (touch wood).

    4. Great video, I tend to get upper back pain (between the shoulder blades) on longer rides. I have a cyclocross bike& they have flared drop bars, it was interesting hearing how wider bars could be the reason why I'm getting this

    5. Despite keeping my arms bent and even relaxing the arms a bit, it seems, it tends to be my shoulders that suffer on long rides. I do go hands free and upright often, but definitely need to concentrate on core strength more.

    6. Speaking about saddle front/aft positioning:
      In my experience, the problem is more often that the saddle is too far to the front than vice versa. The lower the stack of the bike, the more relevant this is.
      The reason is that in a road bike position, pushing the pedals pushes your upper body upwards, just like when you are bending over and getting back up – your butt will go back to balance and support this. If the saddle is too far to the front, on the other hand, the pedalling will not help push/stabilise your upper body, and you will feel this as excessive weight on your hands on the handlebar.
      Meanwhile, it is true, as Si says, that having the saddle further back means the actual reach to the handlebar gets longer. This can be a problem if you have to stretch too far as a result. As a general rule of thumb, you will be stretching too far for the handlebars if the angle between your torso and arms are more than 90 degrees when torso and arms are straight.
      What all this comes down to is that too long of a reach and/or a saddle position too far to the front will mean your lower back will subconsciously have to work to compensate in order for you to not drop your torso or put all the weight through your hands to the handlebars, which will result in wrist pain and unstable steering.
      The other main point from this is that you cannot adjust yourself out of the problem if the reach of the frame is too long. You have to get a bike with stack and reach figures that will fit you. Also keep an eye out for seat tube angle and saddle post setback, as it will alter how you position the saddle to give the right balance.
      As others have pointed out: Get a bikefit from a bikefitter with a good reputation, especially if you are planning on buying an expensive bike!

    7. I enjoy these videos and find them helpful but actually getting hold of shorter crank lengths is not quite as easy as it sounds. Buying shorter crank lengths on new bikes is also not made easy by most brands-bought a lovely Canyon in lock down with integrated power meter which makes this expensive as an option so something I would consider if I buy a new bike again.

    8. Watching this is like listening to people being tortured on a rack complaining about the ropes. All bike pain videos should end with the phrase, "So just ride recumbents."

    9. Shorter crank was recommended for me after an assessment with Phil last week 👍
      Was saddle issues and not back pain, but enjoyed the video and insights from you guys and Phil 👏😊
      Thanks guys

    10. Great video Si and Phil! My upper back complained between the shoulder blades & at the base of my neck. The handle bar width on my touring bike was the culprit. I have a barrel chest but narrow shoulders for a guy so a quick measure between my A/C joints got the data to buy appropriate radonneur bars, then a shorter stem with a higher angle and it all went away. No more overreaching. Bliss! Great content gcn! Love it! Very useful!

    11. Nice video. One thing that shrieks out at me as a bodybuilder primarily, who does a bit of cycling on the side for cardio: you really must think about your posture on the bike: pelvis rotation and straightening your lower back. Rotating your pelvis forward and straightening your back so it follows its natural shape has massive benefits for comfort and power, as well as reach to the handlebars. Doing this also helps to open out the rib cage and improve breathing too. Also helps engage the muscles for greater power, particularly the glutes. Yes, some cyclists will need to work on their flexibility and core strength but posture and knowing how to sit on the bike, with your back following its natural shape is so important.
      I see so many cyclists with bowed over backs looking like tortoises I’m not surprised back problems are not uncommon. It looks really unhealthy.
      Going back to bodybuilding, you would never attempt a deadlift or a squat with a bent over back like that, unless you wanted a slipped disc or a broken back and paralysis. Technique and correct form is everything in bodybuilding, both for safety and performance.
      It is a pity this video just discusses equipment and bike fit without once mentioning technique and how to sit on a bike with correct posture and form, which makes such a massive difference to this.

    12. Excellent video. I had a bike fit in December, not because I want to ride like a pro but because I enjoy riding my bike and I have already noticed a difference in my cycling. This morning I did a 2 hour 24 minute ride and cycled 36 miles with an average speed of 15.2 mph. I included a nice climb near the end. It’s a climb I normally avoid but today I set a PR. When I had my bike fit I asked about aerodynamic bars ; I asked would they increase my speed and performance and he said don’t bother. He said the bike would be fine for me. I feel more comfortable on the bike which is the main reason for doing it. Riding longer distances is the ultimate goal and being comfortable on the bike will help with that

    13. 1) I'm 6'2" and my back pain was managed by lifting (lunges and goodmornings). But it went away altogether when I changed to a wider saddle. (Selle Drakon). Why? Hell if I know. My theory is I'm just generally more comfortable on the bike. I rarely have any back pain now.

    14. I've occasionally found back pain on the turbo. For some reason, the exact same position that feels comfortable on the road can feel far too stretched on the turbo. I'll quite often find myself tending towards the 'puppy paws' position inside, as something that allows my whole back to relax. Generally not an issue outside though.

    15. good video, the only thing I would pick at is the idea that having a stem pointing up is "the wrong way".. I think that just perpetuates the idea that we all need to ride a a bike like the pros do (type and fit) and that, I think we can all agree on, is just silly since the majority of us aren't early 20-something pros at the best fitness of our life.. 🙂

    16. I'd love to see an in-depth series about bike fit. (I mean something well beyond the basic, "If your saddle is too high, your hips will rock; if it's too low, your knees will hurt.")

    17. NOT ENOUGH EMPHASIS ON CORE STRENGTH! I've had back pain for a while now and after endless hours of watching youtube videos and scouring forums…going through rounds of thinking that i've found the issue only to be proven wrong…I have finally figured out that my back pain was from my lower back muscles (mainly ql) taking on too much work in trying to hold up my upper body, compensating for a weak core. Flexion is a difficult position for your lower back to stablize. IF YOU CANT DO A PLANK FOR AT LEAST 1:30 -2 MINS and you have back pain, consider a weak core to be the source of your issues. There are also other muscles that take on a stabilizing role that be under developed, i.e. Glute medius. Warm up these muscles before your ride and make sure to activate your core while riding! Working my core has also helped alot outside of cycling.

    18. If the bike fits right , your body will let you know. In golf we have a saying . Fit the equipment to the golfer.
      You don’t necessarily have to look like a pro. Do what’s best for your back ,Treat your back right, otherwise you’ll never gonna last.
