Mountain bike chain guide

Thank you for your comment. I will soon create a version for older-style cranks like yours. The current version was designed for single-chainring cranks working with a 12-speed drivetrain. I see you have a 32t sprocket. But the outer part around the sprocket mounting bolts is making noise. I will also create a new fin attached under the crank bottom bracket cup to fit external cups as well. If you have any further comments or suggestions, please let me know, I will try to incorporate them into the new design.

almost all chain guides in flagship mountain bikes are made of plastic

But not the base plate 😛

you prolly don’t even need, unless your riding on some crazy and bumpy trails
