I'm new to bike commuting and bought a secondhand trek 820 from an estate sale late July. It's a nice bike, and I've been commuting on it 2-3x and as of this week 5x a week. This week I noticed a buzzing sensation I assumed was my bookbag straps or something like that until this Tuesday when I saw a black stain on my shorts.
I assumed it was my bike seat being too low (I'm working on the height thing) and raised my seat, but I'm having the same problem in a new spot and I think my seat is weirdly tilted? I swear it's the same angle as the top bar of the fucking frame when it didn't use to be.
I didn't take good pictures from the side proir to this because it was a $65 bike but here's a picture of it now. IMG-20241011-022615912.jpg I'm up late so it's not a good one. It's also noticably harder to sit on now. I'm 200 lbs with ??lbs of carry on weight in the form of work clothes and some other stuff but I feel like a bike should be able to handle that, honestly. I have an Allen wrench or two if I need to fuck with the little thing underneath the seat. Thanks for your help in advance.
