Crupi Parts, Inc is proud to release the new Crupi 4-bolt chain ring. Like most of Crupi's products, this new gear is fully CNC machined here in the USA and its quality and performance will match if not surpass the popular 5-bolt ring released nearly 10 years ago. With the increasing popularity of the Rhythm Pro cranks which are now available, the Crupi 4-bolt ring is the perfect match for these cranks along with any 4-bolt model crank. Here are the features of the new 4-bolt ring:

1. CNC machined in the USA for a perfectly flat and round gear!
2. 7000 series aluminum material which is more expensive but also much stronger!
3. Available sizes are 36t through 46t in black and machine finish
4. The unique machined cut-outs around the gear do not penetrate the gear and keep it solid in this area. This not only creates a unique look to the gear but reduces the weight while maintaining its strength and stiffness. With the power riders are laying down today, this strength is a must!
5. A 42t ring weighs just 96 grams!
