![]() Value-wise, these wheels are competitively priced against its rivals. Comparing a pair of 23mm tires on the Fulcrum Racing 4 C17 directly to a set of wheels shod with 27mm tires, the difference in rolling resistance was noticeable - with the total system weight still being close enough as to be unnoticeable. However, the narrow rim width does limit the rolling resistance performance of these wheels significantly compared to other wheels with wider rims that are optimised around chunkier tires. The braking was also brilliant, for rim brakes, and amongst the best I have used, giving greater confidence when descending. Even when setting brake clearance as tight as I dared there was no lateral flex or brake rub when cornering at speed to sprinting out of the saddle maximally. These wheels do fare very well when it comes to stiffness. The Fulcrum Racing 4 C17 is an aluminium rim-brake wheelset which combines a reasonable weight - at 1,727g - with a reasonably deep section 35mm rim for improved aerodynamics.

Thanks to the 24 spokes front and rear, along with the 32t ratchet freehub, the wheels were highly responsive - engaging and accelerating quickly without much in the way of delay or flex. Our measured weight, albeit with rim tape and tubeless valves, was substantially more at 1,571g - which is more than we’d expect.Įither way, on all but the steeper climbs (>12%), our tester found that the Prime Primavera 44 wheels performed excellently. The claimed weight is 1,378g - which is very competitive, especially for the price. ![]() As the name suggests, these come in at 44mm deep, but there are also 32, 56, and 85mm versions for different balances of aero vs lightness.įor many, the 44mm version will strike the best balance of weight and aerodynamics. The Prime Primavera 44 is a great all-rounder tubeless wheelset from Prime’s recently updated range.

Popping a set of Tangente Course G40 tires gravel tires on the rim the wheels really came into their own. In fact, on test, we were able to hit 85km/h and they didn't once so much as give a tiny flutter, even in some gusty wind conditions.Ī low rolling weight and a 66 point engagement hub also means these pick up fast and are capable of showing a clean pair of heels in any sprint. The smoother ride delivers an almost blood like connection with your bike, coupled with the broader rim profile, allows for impressively balanced and confidence inspiring on bike capabilities. The lower tire pressure requirement does deliver a softer ride feel - not to be confused with a slower one. The hookless set up does mean you are slightly limited on the tires which you can use, be we found the ride quality absolutely excellent, with these being one of the best you can currently buy - so we'd very happily accept that slightly narrower choice of tires for the benefits it brings. ![]() These are hookless rims with a 25mm internal width, so need to be run with rubber over 28mm and below 72psi. Zipp's current focus is on producing wheels designed to be run with wide, tubeless tires and at lower pressures. Only works with 28mm+ tires which are hookless compatible ![]()
