Chainguide with roller wheel

thingiverse

This is a precision guide that keeps the chain from whipping wildly around, offering silky-smooth operation every time. To secure it in place, I use a robust 3mm bolt, supplemented by two zip ties and two high-quality 6x2.5mm bearings. Constructed entirely from flexible material, this guide functions impressively well. I've successfully employed it on my trusty 2x10 drivetrain, and while it may work for 3x setups as well, I'm confident it will definitely function flawlessly with a 1x- system. For optimal performance, it's wise to smooth out any imperfections using a soldering iron.
