Extend Your Ride

These posts make great enhancements to endurance road bikes by reducing the chatter transmitted from the surface to the rider and can be tuned to rider weight through a simple elastomer change. #5 elastomer comes pre-installed, other weight elastomers sold separately

Reed Mann

Design Engineer
Name: Reed Mann
Position: Design Engineer
Year started: 2022
Best part of being a part of the Cane Creek family:  It’s very refreshing to work for a small, tight-knit company where we all share the same passions and to develop new products that make cycling better for everyone.
What you’ll find me doing on the weekends: Obviously riding bikes, but also wrenching on bikes or cars, exploring the mountains, and watching F1 races.
How I got here (at Cane Creek): Feeling pretty unfulfilled with a corporate engineering job, I happened to see that Cane Creek was hiring. I jumped at the opportunity to get my hands dirty working on the latest bike tech and was fortunate enough to be offered the position.
