#BikeTooter mixes with #3dprinting. We'll see how these derailleur pulleys work on my computer bike with old Shimano 8-speed RSX. Going from bushings to bearings should be a nice change too. If these hold up, it'll be nice to do this for our MTBs that routinely eat pulleys up. @3dprinting
@idropyou @3dprinting What material are they?
@idropyou I wonder how long they will last.
