Are you becoming such an XC beast that your friends all seem to have to wash their hair on riding day? It's time to deck out your 29er with some race-ready gear to take some weight off and increase your output even more...and wheels are the best place to start. The WTB Stryker TCS Cross Country Mountain Bike Rear Wheel has exactly what you're looking for. It's tubeless compatible (TCS) with rim tape and valve pre-installed--just a little sealant and you'll be rolling. An I-beam design provides amazing torsion strength meaning the Stryker can handle all kinds of abuse while still weighing in at 750 grams...that's light...like road wheel light.

4D rim drilling provides a perfect interface between the rim and spoke and eliminates the need for eyelets
Rim tape and valve are pre-installed; sealant is required to run tubeless
