If you’ve been within the biking universe for some time, Rolf Prima. The Oregon-based wheel firm sponsored the notorious US Postal Service Team in 1999. Their distinctive paired-spoke design wheels had been a mainstay with the enduring crimson, white, and blue Trek 5500, leaving informal biking followers questioning, “How does that even work?” That sentiment hits once more with the 16-spoke Rolf Prima EOS AR wheels.
Fast-forward many (many) years and Rolf Prima continues to be cranking out high quality wheels. They nonetheless make use of the eye-catching paired spoke and craft a number of the extra distinctive wheels on the market.
Rolf Prima EOS AR
The latest addition to the Rolf Prima line is the all-new EOS AR (all-road), which the Rolf crew calls its most superior efficiency base wheel so far.
Only 16 Spokes
How? Like their present ARES AR providing (reviewed right here), the brand new wheels function a 25mm extensive, 40mm deep carbon rim profile and hooked rim design. Rolf added an all-new carbon layup and diminished the spoke rely to 16 spokes entrance and rear.
Why scale back the spoke rely a lot? Rolf Prima says putting the spokes collectively makes an inherently extra aerodynamic wheel. Plus, the equalized spoke-pull creates snappy acceleration. With the EOS AR’s distinctive form and rim energy, Rolf might scale back the spoke rely additional, providing a 16/16 disc brake wheel for the primary time within the firm’s 25-year historical past.
Cerakoted Hub Shells and Ceramic Bearings
The wheels roll on ENDURO XD-15 ceramic and stealth-curated hub shells for elevated longevity and placing aesthetics. The full wheelset weighs solely 1385 grams.
What’s the Weight Limit? Despite the low spoken rely, Rolf attaches no weight restrict to the EOS AR. The engineering crew confidently speaks in regards to the energy and sturdiness of the wheelset. Rolf Prima says the wheel has a extra supple trip high quality whereas sustaining snappy acceleration and exact steering. We have some coming for overview, so save your feedback.
“After releasing this wheel’s predecessor, the Ares AR, we realized that the extensive, deep rim provided energy and stiffness past some other street rim we’d designed. So, we might change the layup to cut back weight with out adversely impacting sturdiness. Because of this rim’s particular design and layup, we might scale back spokes with out including undesirable flex.”
