    Compeititon spokes will give an overall strong build that will last and last. So if your trails are always rough, your bike is packed down, you point-and-shoot rather than pick your line, or you're closer to the weight limits right now, we suggest going this route.


    Revolution spokes are incredibly strong for their weight class -- there's a reason we've stuck with DT Swiss for so many years. This build is intended for the best of both worlds, a light weight, wide carbon wheel set that handles the rough stuff. So build with these spokes if you're chasing friends, KOM/QOM/TOM's or podiums. Performance without compromise. Our suggestion is a total combined weight limit of 200lbs for this build.


    We require brass nipples on builds meant for New York for warranty purposes.
