Syntace may revolutionize the cross-country/all-mountain wheel with its super-wide W-Series rims and wheelsets. The German component maker's brain-trust has developed a lightweight aluminum rim profile that challenges the status quo with four widths, beginning at a paltry, 25-millimeters and ending with a whopping, 40-millimeter-wide rim. In this review, we put the flame to Syntace's 35-millimeter-wide W35 MX wheelset, which could be a trail rider's dream come true, as it promises the precise cornering and stability of downhill wheels at a weight which is competitive with many elite cross-country/trailbike hoops.
Why Wider Rims?
Syntace claims that substantially wider rims better support the tire and help the carcass to maintain its shape while cornering, braking and accelerating. The wider rim is also credited for preventing the tire from collapsing or burping air, in the case of tubeless tires, as high volume tires often do when mounted on conventional-width rims. This news should come as no surprise to downhillers and free riders who have long been enjoying the stability and precise cornering which results from the added support of 35 to 40-millimeter-wide rims. Why that news did not reach the ears of cross-country wheel designers until now is not known, but you can bet that Syntace's W-Series wheels have caught their attention.
