The Rolf Prima EOS AR wheelset is a high-performance, all-road carbon wheel designed to excel on both paved roads and gravel terrains. Priced at $3,099, it features a 25mm wide, 40mm deep carbon rim profile with a hooked design, allowing compatibility with tire widths ranging from 28mm to 50mm. (rolfprima.com)
A notable aspect of the EOS AR is its reduced spoke count of 16 front and rear, achieved through Rolf Prima’s paired spoke technology. This design enhances aerodynamics and equalizes spoke tension, contributing to snappy acceleration and precise steering. Despite the low spoke count, the wheelset has no rider weight limit, reflecting its strength and durability. (bikerumor.com)
The wheelset is equipped with Enduro XD-15 ceramic bearings and stealth cerakoted hub shells, which improve longevity and provide a sleek aesthetic. The hubs are part of Rolf Prima’s XST 7.0 Centerlock system, featuring a T2 High Engagement drive system and a CNC machined 6al4v Titanium freehub body. (rolfprima.com)
