For those that love the 27. 5in rim size for all-mountain pursuits Race Face delivers rugged reliability with the Aeffect R 30 Boost Wheels. The terrain-loving rippers out of Vancouver British Columbia built the Aeffect R 30 to handle relentless punishment on the trail when you only see an obstacle as an opportunity to push the limit. Weighing in at 1920 grams for the set the Aeffect R 30 is designed to withstand heavy use and consistent chatter on the trail while also remaining balanced and nimble to accelerate and ease up at a moment's notice. Race Face uses the new Trace hubs with full cartridge bearings to extend the life and durability of the wheels and they also boast a competitive 9. 2-degree engagement using a durable three-pawl design. J-bend steel spokes are offset to provide stiffer support essentially elevating the wheel to workhorse status so you can stay confident no matter where the trial takes you.
