Profile-Design TwentyFour 58/78 – MSRP $1899.98
Profile didn’t just copy what others were doing with their new wheel line. They used computational fluid dynamics software to create a proprietary rim shape and hub shell for aerodynamics and a carbon lay up Profile claims will make these wheels both fast and durable. A high-temperature resin that won’t melt under hard braking and a custom pad material combine to increase braking performance. The rim is 24.5mm wide and as the name implies the front is 58mm deep and rear is 78. These wheels are 10- and 11-speed compatible for Shimano, SRAM and Campagnolo. They come with skewers, brake pads, rim strips, extra spokes, a spoke tool, valve extenders, extra nipples and even tire levers.
As with the other wide rim carbon clinchers in this comparison, the Profile 24′s exhibit a ride quality that is noticeably better than the standard width. I rode them with a 25mm training tire and felt like I was on perfectly smooth roads no matter the true condition of the pavement. The 58mm and 78mm depths mean better aerodynamics, but also more area for side winds to catch. Lighter athletes or those that aren’t comfortable in windy conditions should consider a 58 for the rear. It’s hard to quantify if the proprietary rim shape is faster than others, but they certainly feel fast. These wheels feel better the faster you go, holding their speed well. Some of that sensation can be attributed to their 1,724g weight, which helps give these wheels a quick and snappy feel. Stopping power is fantastic with a strong initial bite and minimal fading. For under $2,000 you’d be hard pressed to find a better set of race day wheels. Profile-design.com
