HED has pushed themselves back into the premium wheel world with their slippery fast Vanquish series rims and wheels. The full carbon rim designs are disc brake only and tubeless ready with a hook design that allows you to opt for clincher tires if desired. The proprietary Vanquish RC Pro rims are made by hand in Minnesota, U.S.A. and undergo an unprecedented level of quality control. The RC4 Pro rim shape itself is all-new, with an impressive 30mm max external width combined with a 21mm internal width. This results in superb aerodynamic performance with 23-28mm tires, with drag numbers that dip below -300g, with serious stability and a great ride quality. Ideally, this is an attacking wheelset for days when the climbs are as crucial as the descents. In fact, the RC4 tests fastest with a 25mm tire, which feels perfect for the overall 40mm depth and the 30mm width of this Vanquish RC4 Pro Front Wheel when grip and control need to augment speed and efficiency.

The Vanquish RC Pro's 110 GSM carbon fiber rim construction makes it lighter, stronger and faster than the competition. The width, shaping and tubeless construction has a hybrid spoked-carbon design, creating a stiff and efficient wheel for optimal handling and control. The rim is the crucial component of the Vanquish RC4 Pro Front Wheel, and it rolls fast and true on the HED 515 Center Lock Disc Front Hub, with it's oversized alloy axle, smooth sealed bearings, and stout flanges. The flanges are built for speed and carry 24 j-bend spokes, while the rim design allows them to run 2x/2x in high tension. This optimal with the lightly bladed stainless steel Sapim CX-Ray spokes, which are also lightweight and offer superb ride quality. With a 12/100mm thru-axle configuration, the overall hub and wheel assembly offer great stiffness and efficiency throughout.

At 669 grams bare, this low mid-section aero wheel is more than competitive in that respect, and again, it tests impressively fast without compromising control in the wind, or stability while accelerating or cornering in extreme situations. You can match it with the Vanquish RC4 Pro Rear Wheel, or even opt for the 61mm deep Vanquish RC6 Pro Rear if you prefer that type of combination for a rolling triathlon or long, fast, flat and rolling road race.
