In order to give the 29er fork RS-1, which comes in an upside-down design, more stiffness and steering precision, the engineers have reached deep into their bag of tricks. The clamping of the front wheel hub uses a 15 millimetre thru-axle, which is surrounded by an aluminum tube called a "torque tube" and offers large, positive end stops at the transition to the dropout of the fork.

From Sram and new DT Swiss
This system-integrated front hub is currently emblazoned on the front wheels of the Sram Rise XX, Rise 60 and Roam 50 series. As already announced at the launch of the RS-1, DT Swiss is also launching new hubs for the "Predictive Steering" standard. Here are the details:

240s hubs
DT Swiss is adding a "Predictive Steering" model to the 240s hub series for individual wheel construction in straight pull design. This weighs around 178 grams, accommodates 28 spokes and has a 6-hole disc mount

And on top of that, system front wheels
The Biel-based parts specialist has added a front wheel variant for the new Rock Shox fork model to the XR 1501 Spline One competition wheel launched in 2013: naturally, this wheel called XR 1501 Spline One 29" Predictive Steering is 29 inches in size, has a rim width of 20 millimetres and weighs around 1540 grams as a wheelset including the rear wheel.

For all those who are looking for demanding all-mountain use or simply want a wheel that combines stiffness, low weight and price/performance, the XM 1501 Spline ONE 29" is the perfect choice for the new RS-1. Here, the rim width is 22.5 millimetres and the weight including the rear wheel is around 1700 grams.

Variable freewheel
The rear wheels matching the XR 1501 Spline ONE 29" and the XM 1501 Spline ONE 29" are available with both Shimano and Sram XD freewheels. According to DT Swiss, the products presented will be available from specialist retailers from summer 2014.
