Crupi's original chainring CNC machined from 6061-T6 aluminum plate right here in the USA. Machining rather than stamping our rings ensures that each gear is perfectly round and flat. This helps eliminate tight and loose spots in your chain. Select sizes only while supplies last including some sizes in Raw Aluminum where you can polish them or anodize them on your own if you like; or just run em' raw!
- Designed to fit any crank with a 110BCD 5-Bolt spider
- Chain fit = 3/32"
