For those who’ve been within the biking universe for some time, you understand Rolf Prima. The Oregon-based wheel firm sponsored the notorious US Postal Service Group in 1999. Their distinctive paired-spoke design wheels have been a mainstay with the long-lasting purple, 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.
Quick-forward many (many) years and Rolf Prima remains to be cranking out high quality wheels. They nonetheless make use of the eye-catching paired spoke and craft a few of the extra distinctive wheels in the marketplace.
Rolf Prima EOS AR
The latest addition to the Rolf Prima line is the all-new EOS AR (all-road), which the Rolf workforce calls its most superior efficiency base wheel so far.
Solely 16 Spokes
How? Like their present ARES AR providing (reviewed right here), the brand new wheels function a 25mm large, 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 cut back the spoke rely a lot? Rolf Prima says inserting 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 power, Rolf might cut 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 whole wheelset weighs solely 1385 grams.
What’s the Weight Restrict? Regardless of the low spoken rely, Rolf attaches no weight restrict to the EOS AR. The engineering workforce confidently speaks concerning the power and sturdiness of the wheelset. Rolf Prima says the wheel has a extra supple experience high quality whereas sustaining snappy acceleration and exact steering. We now have some coming for overview, so save your feedback.
“After releasing this wheel’s predecessor, the Ares AR, we realized that the large, deep rim supplied power and stiffness past some other highway rim we’d designed. So, we might change the layup to scale back weight with out adversely impacting sturdiness. Due to this rim’s particular design and layup, we might cut back spokes with out including undesirable flex.”
