Product details


SYNTACE rim 28 "W21i aluminum | 24 holes

Based on the tried and tested aluminum rims of the W series for mountain bikes, Syntace developed the W21i rims for the growing bicycle category of gravel bikes and racing bikes with disc brakes. With an inner width of 21 millimeters, it offers 25 - 40 millimeter wide tires, even with very low air pressures, very good support. The special inner profile of the rim ensures easy tubeless assembly without a compressor. The hooks on the rim horns guarantee a secure fit of tubeless tires even in extreme situations. In contrast to cheaper rims, the rim joint of the W21i is welded. This design makes the rim stiffer and leads to better concentricity in the spoked wheel. With a weight of only 425 grams, the rotating masses remain very low, which has a positive effect on the acceleration.

The enlarged nipple seat diameter (spoke hole 5.1 mm) enables the nipples to be embedded at the correct angle and prevents the spokes from buckling when the number of spokes is small and the spoke length is short. The spherical contact area of the ABS lock nipple on the spoke hole guarantees perfect alignment with the spoke and a force-based structure is achieved on highly loaded wheels.

Stronger than the spoke
Much more crack-resistant spoke anchoring in the rim base thanks to the SmoothFit profile. Perfectly angled embedding of the nipples in the rim well. More durable than previous rim bases or mere washers, which add weight to the rim but do not reinforce the edge of the spoke hole.

This rim has 5.1 mm spoke holes and requires the ABS Lock FG2.3 spoke nipple developed by Syntace to build a wheel!

V shape
From the inventor of the heavily reinforced rim flanges on MTB rims, which are inclined outwards. Tread created in a long series of tests with retaining groove for the best possible tire fit. 25% higher stability as well as the tire width and traction of a 2 mm wider rim.

Syntace grants a 10-year guarantee on its items if they are installed and used in accordance with the installation instructions.
