We're all well familiar with the rim encircling WTB's tubeless Ci24 TCS DT Swiss 240s 650b Wheelset. WTB describes its preferred terrain as "menacing," and rightfully so—the things have lumbered through damn near every big-hit Mecca around the world. But this wheelset isn't built for those hits, though its intended terrain is as menacing, just not in the same way. These wheels are tailored for road+, 650b bikes, so instead of lumbering over big hits, they're built for spinning up gravel passes beneath a fully loaded bikepacking rig. They're not for carrying you to finish lines; they're for carrying you to the next camp site.
Despite their different application, these rims are built just like they're enduro counterpart. They werre two years in the making, and those two years were filled with countless tests and tweaks to create a rim that's strong in all the right places. WTB utilizes its 4D Drilling technology, which angles the spokes for even alignment of the nipple and hub flange to eliminate unnecessary lateral stress. This serves to increase the wheels' longevity and ability to handle bikepacking loads. Additionally, the Ci24's ample 24mm internal rim width provides a solid platform of support for plush traction and pneumatic cushion on ungraded gravel roads.
These rims incorporate WTB's Tubeless Compatible System (TCS) profile and pair with TCS or UST tires for easy, reliable seating and excellent flat protection. Preventing flats while you're two days into the backcountry is a decidedly good thing. The rims are also compatible with tubes if your sealant can't fill the puncture hole.
The rims are laced to DT Swiss' venerable 240s hubs, whose star ratchet design has become an oft-copied staple across the industry for a good reason. And that reason extends beyond the freehub's signature hum. It's a reliable, low-maintenance design that doesn't need to be babysat in order to guarantee its fast engagement and durability.
