Quality components for a stellar ride.

Wilderness Trail Bikes, or WTB, was founded in Marin County, California in 1982 and through its tenure has gained a wealth of knowledge when it comes to crafting reliable and high-performance components for off-road bikes. Rims are just one area of its expertise and WTB has recently upped their game providing carbon options including these Ci24 rims. This rim has been put to the test on some of the most torturous trails and in this configuration, it's paired with the super-smooth rolling Onyx hubs. The WTB Ci24 TCS Onyx 29IN Boost Wheelset is here to improve your ride with instant engaging hubs and strong, lightweight rims.

The Ci24 rims took two full years of development before they were ready for prime time. Some key features learned during this development giving this rim strength and ready to slay the trail are molded spoke holes and 4D Drilling technology. This angles the spokes for better alignment of the nipple, spoke, and hub flange to eliminate unnecessary loads and provides more even spoke tension. You'll experience a wheelset that is more responsive and stays truer over the roughest trails. The Ci24's 24mm internal rim width pairs well with wider cross-country and trail tires in the 2.1 - 2.4in range and can handle a beating so don't worry about babying them through the baby heads.

These rims utilize WTB's Tubeless Compatible System (TCS) technology and are specially designed for TCS or UST tires for easy tubeless setup and excellent flat protection. We're pretty certain they'll work with any other tubeless-ready tires on the market as well. If you happen to slice a sidewall while out on the trail, you can boot it and install a tube and go about your ride.

The Ci24s are laced to a set of Onyx centerlock boost hubs. The hubs are hand-made in Minnesota and boast ceramic hybrid bearings and Onyx's patented sprag clutch mechanism for instant engagement under power and instant disengagement while coasting. As a bonus, the hubs feature quiet operation so you can take in the scenery and enjoy shredding the singletrack in silent bliss.

What is the weight of this wheelsets?

Hello Valerie,

This wheelset comes in at 1970g without tape or valve stems. Onyx hubs are portly but most people find the true instant engagement and dead silent operation to be work the trade off. If you have any other questions or need anything else, please do not hesitate to contact us.
