Description
The EOS AR is our most advanced, performance-bred wheel to date. With an all-new carbon lay-up designed specifically to maximize the ride quality and weight savings of this model, this model truly has it all and can do it all.
These no-limits all-road speed machines combine a light, stiff, aero, 25mm wide rim profile with ceramic bearings and stealthy, armor-coated hubs in one unbeatable package. Faster than most road-specific wheels on the pavement, yet built to withstand the rigors of gravel, our mini-hooked rims confidently take a 28mm road to 50mm gravel tire. Top of the line Enduro XD-15 ceramic bearings increase speed, efficiency, and longevity so you can ride faster, harder in any condition. The EOS AR is the pinnacle of all-road race performance.
The EOS AR is disc brake only and features our T2 High Engagement drive system and tubeless-easy rim technology.
All Rolf Prima wheels are hand built in Eugene, OR.
"The Rolf Prima EOS AR is amazing. Sure, I've ridden loads of wheels. But this wheelset is arguably the best all-rounder I've ridden to date. Don't let the low spoke count fool you - these wheels are tough, durable and fast."
