Crupi 5-Bolt Chain Ring

A good chainring has always been hard to find and if you wanted to experiment with larger size gears, your options were limited. Why buy a Crupi chainring over the others? Instead of stamping our rings, we CNC machine them from 6061-T6 aluminum plate. This ensures that each gear is perfectly round and flat. This helps eliminate tight and loose spots in your chain. Crupi rings have been the best on the market for over 10 years now!
