DT Swiss EX1700 Spline Rear Wheel Parts

DT’s aluminium Enduro wheelset – made for the toughest Enduro tracks in the world.

DT Swiss has taken all their aluminium wheel know-how and put it in the high performing package. The EX 1700 Spline wheels are based on their solid and reliable 350 36t ratchet hubs combined with the super-strong EX 511 aluminium rims. The rim profile is designed to withstand the hardest use of Enduro racing while still keeping the weight low for long and demanding uphills. Laced to double-butted competition straight-pull spokes, the EX 1700 SPLINE wheels are built to take a beating.

350 Hub:

Sharing the DNA of the famous 240 hubs, the DT Swiss 350 is equipped with DT’s famous Ratchet System. What makes the Ratchet System hubs truly unique is the fact that all teeth of the two ratchets engage simultaneously and create a large contact surface to transmit huge torque. The fact that the whole front face engages, creates much smaller point loads. The result is the legendary reliability of the Ratchet System.

Thanks to the no-tool concept, the hub is very easy to maintain and the freehub body can be converted without the use of any tools.

For the new 1700 SPLINE, the 350 was upgraded by a 36T Ratchet SL system (SL stands for super lightweight, achieved by machined-out ratchets). It reduces the engagement angle to 10 degrees, which DT believe to be the sweet spot in terms of reliability, weight and power transmission.

EX 511 Rim:

The EX 511 is one of the toughest rims out there, not just because of the welded joint, but also because of the specially developed rim profile. The rim is designed for modern Enduro mountain biking. Additionally, although it wasn’t developed for this purpose, some of the fastest downhill racers use it for racing. All this to say: the EX 511 is strong, really strong! With its 30-mm inner width, it’s wider than its sibling, the famous EX 471.

DT Competition Spokes:

The competition spoke is one of the most versatile spokes in the DT Swiss spoke range. DT Competition gets its special strength from a specific cold forging process. This process, developed and patented by DT Swiss, is used to double-butt the diameter of the spokes. Oscillating hammers rotate around the wire.

As a result, the spoke material is densified and its diameter is reduced. This cold forging process hardens the material while ensuring that it retains its good ductility. The result is a spoke with a slim butted section for low weight and a strong head and thread for durability. This leads to extremely high durability and furthermore, thanks to the thinner middle section, it is lighter than a spoke with a constant diameter of 2.0 mm.

Hand Built:

Reliable components are not enough to create a reliable wheel – the final step is decisive.

The way a wheel is built is what turns quality components into a quality wheel.

Like all wheels developed by DT Swiss, the 1700 Spline is assembled by hand. With the highest precision and the smallest possible tolerance, which until now would never be reached by a conventional wheel building machine, hundreds of wheels are assembled every week in Switzerland, Poland, Asia, and in America – by hand.
