Spinergy GXX Carbon 2021 model comes with an improved hub design - a beefier "44" hub with bigger internals, featuring 108 points of engagement. The improved design enables you to generate more torque and power transfer for your performance. Wheels have been upgraded to 44mm ratchet rings offering compatibility with Shimano Micro Spline 12-speed and Campagnolo Ekar 13-speed groupset. The all new "44" hub has a slip-fit system so you can easily swap out end caps to accommodate 15mm, 12mm or QR axles.

Spinergy GXX Carbon rear bike wheels offer a lot of functional and performance features sought by gravel, off-road, extreme off-road, cyclo-cross and mixed terrain riders. Heavy duty wheels are built to withstand the effects of hits and falls on uneven roads and dirt tracks. Extreme riders will appreciate the lateral stiffness and improved cornering stability.

The main highlight of Spinergy GXX wheels is the unique, patented PBO fiber used in spokes. GXX also features proprietary foam core carbon rim, which is stronger and stiffer while keeping out water and dirt. Each spoke is made of 30,000 strands of Polyphenylene Bensobisoxazole fiber, offering 3 times strength at the half the weight of traditional stainless steel spokes.

Spinergy wheels are a great choice for CX riders and racers. Innovative PBO construction has the benefits of lower rotational weight and fast-moving wheels, that is quite exciting for racers.

Adventure riders can count on the confidence and comfort offered by the excellent vibration dampening benefit of PBO, which is a huge benefit compared to traditional wheels with stainless steel spokes. This helps riders have better traction and control on different trail conditions.

GXX wheels are tubeless ready. The lightweight wheel with 24 spokes and 24 mm internal width, is compatible with 40mm or wider tires up to 54 mm.
