Reserve 30|XC SL DT180 29" Wheelset Light, Fast, World Cup Proven XC racers and hard-charging trail riders who have been waiting for a wider-profile carbon race wheel now have their answer. The 30|XC SL pairs SL-grade carbon rims with Vonoa carbon spokes and DT Swiss 180 hubs - the lightest, stiffest combination Reserve builds for XC. The SL rims shed 30 grams per rim over the standard 30|XC through a special carbon layup with a greater proportion of high-modulus fiber, and the 30mm internal width adds real tire sidewall support that the older 28mm XC standard simply cannot match. Asymmetric rim construction improves spoke bracing angles and equalizes tension between drive and non-drive sides, which translates directly into a stiffer, more responsive feel when you're out of the saddle on a hard climb. A 28-spoke build gives this wheel enough structure for the increasingly technical descents that World Cup XC now demands, without piling on weight you'd feel on every punchy ascent. Reserve backs it with a lifetime warranty and no rider weight limit. Features SL carbon rims with 30mm internal width save 30g per rim versus standard 30|XC through high-modulus fiber layup while maintaining identical strength Vonoa carbon spokes 30% lighter than steel spokes, reduce spoke wind-up for faster acceleration and a stiffer, more planted feel DT Swiss 180 hubs lightweight benchmark hubs with global serviceability and broad driver body compatibility28-spoke count with asymmetric rim design improves spoke bracing angles, equalizes drive and non-drive tension, and adds descending confidence over 24-spoke XC builds SPECIFICATIONSWheel Size29"Rim Material Carbon (SL high-modulus layup)Inner Width30mm Spoke Drilling28Valve Type Presta Tubeless Yes Tire Type Clincher, Tubeless Brake Compatibility Centerlock Front Axle15mm x 110mm Rear Axle12mm x 148mm Intended Use XC | Reserve Wheels | Reserve 30 | Xc Sl Dt180 29" Wheelset Set, 15Mm Boost, Centerlock, Xd And Ms
