It's no secret that wider rims and tires contribute to more grip and traction. Not only do you get a larger footprint, it also allows you to run lower pressures for more cushion and a more comfortable ride. When it comes to wide rims, usually it comes with a weight penalty, or rims are made so thin in an effort to save grams, that they aren't very stiff or dent at the sight of a rock garden. That changes when you add carbon rims to the mix and with brands like e*thirteen and its crew of hardcore riders and engineers testing carbon wheelsets in the most demanding terrain, you can have your cake and eat it too. So if you're looking for a plus wheel upgrade or need to pick out some hoops for that new plus build, have a look at the 27. 5 Plus TRS Race Carbon Boost Wheel and get ready to add an injection of rock crawling trail traction that can only come from a stiff, wide carbon rim shod with a girthy, low pressure tire. Additionally, the Race Carbon Plus wheels boast large hub flanges and short spokes to further boost stiffness and contribute to sure tracking. The front and rear hubs are constructed from lightweight carbon fiber and feature machined aluminum flanges for zero windup under accelerations and braking and an impressive amount of lateral stiffness. These wheels feature an impressive build and don't flinch when subjected to the most technical terrain under aggressive riders and have been refined through a healthy dose of feedback from World Cup DH legend ron Gwin. The TRS Race Carbon Plus is at home between the tape as well as on all-day rides where you're only concern is finding another water source. Like all e*thirteen carbon wheels, this one is backed with its lifetime warranty. Inside the Boost width hubs are angular contact bearings that spin freely, hold up well against the elements, and are better able to cope with lateral forces than standard cartridge bearings, thus lasting longer.
