With two different rim heights, hook rims, and Ratchet EXP freehub, the carbon cyclocross wheelset enters the next generation - paving the way for clincher tires in cyclocross.31.03.23 08:46 4322023-03-31T08:46:00+02:00

Until now, the DT Swiss CRC 1400 Spline introduced in 2018 with CX World Championship gold and silver, featuring 24 mm rim height, have been considered the wheelset for all challenges off the roads - where dirt makes the teeth grit.
Thanks to the fundamental revision, the now suitable for clincher carbon rollers are supposed to cope with the roughest conditions and excel in the most adverse CX circumstances. The accompanying claim skillfully plays with the German word for cyclocross and reads:

Jump into the mud - with the new CRC 1400 Spline

Two Heights, Two Worlds

Tubular tires are as common in cyclocross as they are cumbersome in (initial) handling. We have only recently dealt more closely with the advantages and disadvantages of different constructions as well as the reasons for their popularity in CX here.
For fans of glued tires, the popular CRC 1100 Spline 38T will continue to be available. Those who want something more exclusive can look forward to alternative types of tires in the future. But let's take it one step at a time.

First and foremost, the new CRCs are a whole or even very whole lot taller. For the first time, DT Swiss is offering two rim heights in its Cross Road range: 35 or 45 mm, aiming to cater to two different riding styles or specific requirements.

CRC 1400 Spline 35 - fast and light. The agile competition model is designed to ensure efficient progress in muddy and technical sections.
CRC 1400 Spline 45 - aerodynamic and robust. More suited for longer cross events, the taller version aims to outmaneuver drag as well as withstand all obstacles.

Both variants are carved from the same wood, namely: carbon, and there should be no differences in technology.

The two-time Swiss CX champion Alessandra Keller about the new CRC: "Despite the muddy conditions at the National Championship, I had full confidence in my wheels. They felt really fast, and since I could ride them with very low air pressure, I had good grip and riding comfort, so I could save energy for the battle against my competitors."

With Hooks and Ratchet EXP

In contrast to its predecessor, the new CRC 1400 Spline wheels feature hooks at the rim flange. Although more complex in development and production, DT Swiss has opted for this design for safety reasons (keyword Burping) and choice (more compatible types, sizes, systems of tires).
Fundamentally, the wind tunnel-optimized rims are tubeless-ready and have a rim width of 22 mm, the same as before.

For the new CRC generation, DT Swiss is switching from hookless TSS rims to Crotchet tubeless TC.

New in the DT Swiss Cross Road Range: the lightweight Ratchet EXP freehub system.

In terms of freewheel technology, the Ratchet 36 SL system is upgraded to the lighter Ratchet EXP with also 36 teeth. Because the tooth disk and threaded ring are combined and only one guided spring (instead of two in the classic) is used, the interlocking is particularly precise. In addition, the integrated design allows for a higher bearing spacing, which, according to DT Swiss, increases axle stiffness by 15%.
Other advantages of the system: longer service intervals and tool-free handling. Moreover, the hub body has been revised. Slimmer and stiffer, it is expected to positively affect aerodynamics and durability.

The set weight of the noble mud-splatterers built with 240 hubs and 24 Aerolite or Aerocomp Straightpull spokes each is according to the manufacturer 1,424 g for the 35-mm version. The taller variant weighs twelve sugar cubes more (1,475 g). Both the competition and long-distance models are limited to a maximum system weight of 120 kg.
The prices, regardless of the rim height, are 860.90 euros for the front wheel and 1,188.90 euros for the rear wheel - totaling €2,049.80.
