29 "MTB carbon wheels
Ask Jaroslav Kulhav, and he will tell you: Every gram counts in the rally races. But with the XC tracks becoming more aggressive than ever, the simple fact of being an ultralight wheel is no longer enough. Now, the wheels must be as hard and light as they are light, with all the driving characteristics that XC veterans expect. Introducing the new Control SL 29 148 Boost.
When our riders asked us for the best cross country wheels, we knew they were really asking for some pretty specific features. They should be lightweight to be competitive in terms of inertia and weight, strong enough to support rocks and roots, and wide enough so that the tire profile was optimized for both traction and traction. for rolling resistance. It is not an easy task
To fulfill all these characteristics, we started by looking at our Traverse SL tire to see if we could extract the benefits of the wide tire while maintaining the weight in the previous SL Control or lower, the existing reference. Based on the width that we knew was ideal for the desired driving characteristics, we tuned the shape of the rim to optimize the rigidity, weight and running quality of the system: too high and the wheel it moves too fast, too shallow and the wheel is very flexible. Our engineers meticulously studied the developments of the rim shape to find the perfect balance and geometry, and after adjusting multiple iterations and itineraries, we end up with a rim of 25 thousand internal width that is approximately the same weight as the previous Control SL.
Being able to add material and width (3 mm to be exact), without a weight penalty makes a wheel stronger XC, but we are not happy with just an increase in strength. With our goal of being the fastest racing wheel game available, we take new and old tires, combine them with a Fast Trak size 2.0 tire set and perform rolling resistance tests to both 20 to 30 PSI. & iquest; The result? The new wider edge prob & oacute; more quickly to both pressures, which confirms our hypothesis on the whole that the width is not only stronger, but also faster.
Maintaining the Zero Bead Hook design, the new Control Wheel SL keeps all the most sought-after features that come with this design impact resistance, added, easy tire installation. no tube and better sealing of the tire on the rim. And with a lighter hoop, it is also rewarded with extremely low inertia, which translates into faster accelerations for the intense efforts required in XC careers. Centering on the wheels as a system, we kept with our light-weight basic design tenants and durability, as well as We make sure not to skimp on construction. Each wheel is hand made, and while it is a lost art, we know that a real person can achieve qualities that a machine simply can not. When you build your hands, you can find small discrepancies that would otherwise be lost in a machine, as well as We take the refined 2Bliss Ready tire and combine it with our CNC machined centers with DT Swiss Competition Race spokes. The inner parts of the hub have sealed bearings and internal DT Swiss 240 with a ratchet in star of 54 teeth in the rear, which allows a quick coupling.
Finally, with the 110/148 variant, you will receive & oacute; all the benefits that Boost Spacing offers. By increasing the width of the front and rear hub flanges and, in turn, increasing the clearance and rigidity of the frame and the fork, you get a faster, stronger and longer lasting system with a small footprint. weight penalty.
If you need a set of wheels less than 1400 grams, ready for the race, that has the handling and strength of a modern trail wheel, the Control SL 29 148 is the perfect choice.
