Picked up this Emonda ALR 5 about a month ago now. I’ve been loving it, but i noticed this odd defect and I am wondering if this is cause for concern or if it is purely cosmetic. Only thing I’m thinking right now is since it’s an aluminum bike, if it may be subject to corrosion right there. I’m pretty new to these higher end bikes (i.e. my previous bike was from Amazon, lol) so any input is greatly appreciated.

    1. ALR is 300 Series Alpha Aluminum frame which while it is the best finished aluminum frame from TREK, still you might notice some small imperfections on the welding joints, like the one in your photo. You should not be concerned about that tiny cosmetic imperfection.
