The time has come. Now.

The starting shot has been the wide Syntace W-Series alloy rims. Back then as well as today the unrivaled combination of lightweight and durability. Syntace wanted to transfer two decades of experience in the manufacture of carbon parts on rims aswell, but without disadvantages in robustness and price. That was finally successful.


The V-shape design is coming directly from the initial founder of outward-bound and massively enhanced rim flanges on mountain bike wheels. The shape has been tested and approved in uncounted series of experience and now features grip grooves to generate ultimate tire interlinking. It is 25 % stiffer and boasts with the performance of of a rim that actually is 2 mm wider looking at the tire width and the adhesion on the ground.

Lightweight carbon fiber to make you faster!

Energy saving carbon fiber rims did always come with compromises in the past. They have been expensive and either not particularly durable or not particularly lightweight, if they were at all.

Thanks to tireless designing, special tool con­structions and a new carbon fiber layup, we succeeded in combining the advantages of the material. The Syntace C-Series carbon fiber rim stands more impact than any Aluminum competitor we know of and remains – despite the inner width of 33 mm – extra­ordinarily lightweight (435 g for the 27.5” rim). The unbeatable price is the result of the ­all-new high-class Syntace 
production procedure.

Wide widths and low weights save energy.

Narrow rims and heavy tires were common in the past. It has become possible, however, to combine wide rims with lightweight tires. It is just that wide rims have always been heavy or they have not been particularly durable, a vicious circle that carbon fiber stopped. The wider the rim and the bigger the rim diameter, the more the advantages of the material carbon fiber come into play in the Syntace C-Series wheelset. On top of this, the inertia of the rim/tire combination is noticeably lower.
