TECHNOLOGY

SDM RIM TECH
To make strong, durable rims, we add extra layers of carbon to some of the most important parts of your wheelset.

SDM BRAKE TECH
We apply an extra layer of basalt fiber to every SDM Braking surface, which gives you noticeably better braking performance and extraordinary durability.

SDM HUB TECH
We’ve built an over-class hubset into our SDM designs. The BiteX Ceramic hubset is designed to have extra-strong wheel geometry, durability and smoothness…

SDM SPOKE
It might seem like an obvious fact for any road bike, but we’ve seen again and again that thicker spokes make for a stronger and more durable wheel.
