Synthesis XCT Carbon Boost Wheelset
Mountain bike technology has progressed rapidly over the past 5 years, but one place that could us some improvement is carbon fiber wheels, which can have a harsh ride quality that may not actually improve performance over their aluminum counterparts. Crank Brothers aims to change that with the Synthesis XCT Carbon Boost Wheelset. These new-age hoops are specifically tuned for XC racing, putting both stiffness and compliance together in a single wheelset by crafting one rear-specific wheel, with elevated stiffness for exceptional tracking, and the other front-specific, tuned for compliance, grip, handling, and a bit more vibration damping. These are each laced up with different spoke counts, landing with a stiff rear-wheel that doesn't compromise tracking in steep and loose corners, and a front wheel that holds its line, and soaks up harsh trail chatter.
To start to understand the Synthesis XCT Wheelset, we need to look at the differences between each rim. The front rim uses a wider profile, with an inner rim width of 26.5mm that supports wider tires and does a better job absorbing trail chatter, meanwhile amping up the traction to keep you locked into your line in loose corners. This rim is laced up with 28 spokes — 4 fewer than the rear wheel, allowing just a little more compliance to elevate vibration damping. In the back, Crank Bro's opt for a slightly narrower rim with 24.5mm internal width, laced up with a whopping 32 spokes for a stiffer feel that offers undeniable control, power, and tracking.
This version of Crank Brother's Synthesis Carbon Wheels finds itself laced up neatly to the Synthesis Standard hub. While we admit, it isn't quite as flashy or fancy as the Synthesis 11 on its counterpart, the Standard still offers quick 17-degree engagement, which is plenty to get you up and over punchy climbs, and it comes with a significant savings to your pocket book, so you won't have to spend all summer apologizing to your significant other for the dent you put in your savings.
