FACTOR 21(27.5) / Carbon Trail Wheels

The tubeless-ready carbon hoops are 33mm deep, and use Novatec's proprietary bead lock technology and Matrisilk structural reinforcement to hold true their 23mm internal-width rim. During our testing we bashed these things into sharp rocks regularly, and have yet to discover any signs of weakness. Rim stiffness is better than most other wheels on the market, and we felt confident laying our test bike over, knowing the wheels would roll where we pointed them.
