I got a spanking pristine set of the new Sun Ringlé Charger Pro wheels in the late winter, and I have put them through a beastly thrashing, and they are light, fast and amazingly tough. The Charger Pro is an All Mountain wheelset which is available in 26″ or 29″ sizes, featuring tubeless ready aluminum rims that come with swanky labeling that screams, “Go Fast”.
Sun Ringlé partnered with Stan’s No Tubes to license their patented BST (Bead Socket Technology), to give the Charger Pro rims proven tubeless compatibility. The BST system allows rims to have a wider inside dimension than other designs, offering a wide base for the tire. The design has shorter sidewalls, that help reduce pinch flats and rim denting from running low pressures.
The wheelset comes with Stan’s yellow tape installed, and valve stems and mini bottles of sealant in the box, so everything is ready to go. The rims are 28mm wide, and use Wheelsmith double butted spokes connected to direct pull hubs, using 24 holes on the 26″ version (alloy nipples) and 28 holes on the 29er (brass nipples). The kit also comes with 9mm, 15mm and 20mm adapters for the front hub, which is really unique, since most companies offer additional adapters only as an option. The rear hub comes with standard QR 135x9mm (as tested), but can be optionally ordered in 135x12mm or 142x12mm versions.
