The Stan's ZTR Race Gold 29er wheel comes in at a scant 626 grams and even lighter if you convert it to 15mm thru axle with the quick and easy Stan's 15mm adapters. This low weight was achieved by careful engineering of proprietary products. Add the rear Race Gold wheel for a pair that will come in at 1350-1375 grams. Yes it is light, but we have found them to be durable as well. They are quite possibly the best XC wheels ever constructed.
The Race Gold rim is carefully extruded to remove any excess material and uses Stan's tried and true Bead Socket Technology (BST) . BST offers a shorter sidewall with more tire bead support and improved air volume. This design also allows the weight of the rim to be reduced while the strength of the rim is improved. The weight of the Race Gold rim is an astonishing 320 grams.
The hubs are Stan's own ZTR variety. They feature sealed bearings, high flanges with weight reducing cut-outs and a 6 bolt disc mount. Stock hub is set for a 9mm quick release skewer, however you can convert it to 15mm thru-axle with Stan's 15mm end caps. The conversion takes about as long as it took you to read this sentence. The spokes are DT Swiss Revolutions in black anodized. They are custom drawn at 1.5mm-1.8mm for a weight savings measure. The wheel is laced in a 2x pattern.
If you are looking for the ultimate lightweight XC 29er wheel that is durable for real world use, you may consider the Race Gold. It comes pre-taped with Stan's Rim Tape and included a UST valve. Weight of the front wheel is 626 in the 9mm iteration and approx 20 grams less when converted to the ever-popular 15mm thru axle.
Please note: Stan's BST rims are not compatible with WTB TCS and some UST specific 29" tires.
