DT Swiss GRC 1100 DICUT 30 Rear Wheel - 28" | Carbon | Centerlock - 12x142mm - Micro Spline + Shimano HG

GRAVEL!

No cars, untouched nature & endless roads. What used to be the terrain of mountain bikers now also fascinates road cyclists. DT Swiss Gravel wheels offer the perfect blend of comfort, durability & off-road performance. Made for countless off-road adventures.

GRC 1100 DICUT

Leave nothing to chance and prepare meticulously. With the GRC 1100 DICUT you are perfectly equipped, whether you are hunting for victory on gravel roads with the 50 mm rim or testing your limits on an extreme off-road adventure with the 30 mm rim. The current gravel wheels are manufactured in a state-of-the-art production process. The result? Lightweight carbon rims straight from the mold that require no further processing or painting. They are not only a real eye-catcher, but also save valuable grams in addition to their special aero optimization. The rims are equipped with the best components: the lightweight 180 DICUT hub with ceramic bearings and DT Aerolite II spokes, which ensure good acceleration and low rolling resistance.

Legendary reliability | The wheels in the GRC series are designed to provide gravel riders with components they can rely on 100% when riding off-road. Thanks to manual work, not only is precise manufacturing quality achieved, but the well-known, brand-typical reliability is also ensured.

Ratchet Freewheel system | The special feature of the patented freewheel system is that all the teeth of the two toothed pulleys always mesh simultaneously. In contrast to pawl freewheel hubs, where the meshing surface is comparatively small, the loads are distributed evenly over a large contact surface due to the inclusion of the entire end faces. The result is a significantly lower point load and therefore much greater reliability.

Pro Lock Technology | The DT Pro Lock spoke nipples prevent the spoke-nipple connection from loosening on its own. A patented two-component adhesive is injected into the nipple thread, which enables the construction of extremely durable wheels. As soon as the nipples are screwed in, the adhesive is activated and then hardens completely. Repeated re-centering is possible without any problems, although the adhesive strength decreases slightly with each re-centering.

Properties of the DT Swiss EXP freehub body

The new freewheels with EXP spur gearing: lighter, stiffer, more precise and easier to maintain. The strengths of the Ratchet freehub have been further improved by the new EXP technology.

DT Swiss EXP technology:

Easy maintenance

...thanks to a small change to the end caps.

An integrated notch and the newly developed shape of the end caps simplify disassembly considerably, making maintenance much easier.

Replacing the freewheel

Now also simpler thanks to the simplified disassembly. The tool-free concept allows conversion to a different drivetrain standard within seconds. All DT Swiss hubs with ratchet system can be converted.

Less weight

Reliability is not the only thing that has been improved. The fusion of ratchet and threaded ring reduces the number of small parts in the system, which is a significant advantage. The previous ratchet system required two springs to function correctly as the internal ratchet was not attached to the hub shell. The fusion of the ratchet and the threaded ring in the Ratchet EXP hub not only increases durability, but also reduces the total number of components as only one spring is used, resulting in a reduction in the weight of the freehub system.

Less wear and tear

A single cylindrical spring ensures faster full engagement and therefore increases reliability. Previous systems required two conical springs to ensure the correct angle between the two pawls. The fixed connection between the inner ratchet and the hub shell of the EXP ratchet ensures that the inner ratchet is always aligned at the correct angle. This allows the use of a single cylindrical spring, resulting in faster full engagement and therefore increased reliability.

Superior reliability

The full engagement of the ratchets creates a large contact area and therefore low surface pressure, resulting in high reliability. What makes the ratchet system hubs superior is the fact that all the teeth on each of the ratchets engage simultaneously every time. With ratchet hubs, the engagement surface is rather small. With the ratchet system, the entire face engages, resulting in much lower point loads. The result is the legendary reliability of the ratchet system hubs.

Increased bearing life

By integrating the bearing into the threaded ring, the bearing spacing can be maximized. The increased distance supports the axle further, resulting in less axle deflection and thus protecting the bearings and increasing their service life. The bearing distance is limited by the size of the freewheel system. With the previous system, the bearing had to be placed on the drive side next to the threaded ring, which meant that the distance could not be increased. By integrating the bearing on the drive side into the threaded ring, the bearing distance is increased, resulting in a 15% improvement in axle stiffness.
