Sharing the same design principles as the TR32 but in a wider format for more aggressive XC or “downcountry” riding, NOBL TR35’s are front and rear specific with 3.0mm hookless lips on the rear rims and 2.5mm hookless lips on the front. This creates a more balanced feel between wheels and works great for 2.3”-2.6” tires. Think “downcountry”, modern aggressive XC, trail riding. TR35’s are 28h specific, come in 29” only, and have a sloped and slightly oversized bead seat for a reliable tubeless fit. Built into the mold, is a flat area at the valve for improved seating of the valve collar.
How is it made?
Using a thinner carbon fiber material allowed us to introduce lighter and stiffer T-800 fabric strategically in key areas of the rim. We are able to tune the layup more effectively by using more layers of a thinner pre-preg. A Pre-preg is a fancy word for carbon fiber that has been pre-impregnated with a resin system. The rest of the rim uses Toray’s T-700, with a Unidirectional interior plus a tiny amount of glass fiber around the holes to prevent tear out. We use a 3k twill fabric on the center channel and a smooth finish UD on the exterior to eliminate the need for wet sanding. With this method, the outer layer of resin on the rim is preserved and there is no need to re-heat the rims because no sanding and spraying are necessary.
Stronger Spoke Holes
Spoke holes are offset at the nipple bed in order to create more even spoke tension. We drill our spoke holes at angles to prevent stress risers in the rim or at the spoke/nipple interface and a special bit is used to prevent tear-out. We vary the speed as the bit wears, and monitor the temperature at the holes to prevent scorching. These fine details will lengthen rim lifespan and create stronger spoke holes than other manufacturing methods.
Warranty
As with our other Sinewave rims, they carry a lifetime warranty to the original purchaser. If you break it while riding the rims’ intended use, you will get a replacement rim free of charge. If you missed the notice, we’ve also allowed our 5 year warranty on our Legacy series of rims to be upgraded to a lifetime warranty for a nominal fee at checkout.
