Rim features:
ROCKY KOM 31C 29er
The special layering of the T700 and T800 carbon fibre sheets gives ROCKYROAD rims a high lateral stiffness, while ensuring a high shock and vibration dampening capacity, combined with extremely low weights.
The asymmetric design allows to remarkably reduce the spoke tension difference between the two sides of the wheel, with a big advantage of lateral stiffness and stability.
The special inner profile makes the rim easily tubeless convertible using specific valves and tape.
The 31mm wide inner width fits perfectly with 2.3/2.4" tires.
The 21mm profile improves the absorption of vibrations in the vertical direction, but does not lose lateral stiffness, an important feature for obtaining lightning-fast accelerations and perfect lines.
ROCKY KOM rims are paintless. They come out of the mold as a finished product. Compared with the traditional process, there is no need to polish, so the original epoxy resin layer is retained on the surface, so they have a very strong scratch resistance.
Paintless process doesn't need any post-production like painting, water sanding, etc. So it's even more environmental friendly than traditionally made rims. No wastewater emission during the whole process.
ROCKY KOM rims must pass the stringent tests EN 14766 and ED 14781. These tests have been designed to ensure the strength and durability of individual parts as well as of the bicycle as a whole, demanding high quality throughout and consideration of safety aspects from the design stage onwards.
ROCKY KOM rims are intended for XC / Marathon use.

Our wheels are built by hand in house by highly specialized personnel.
The Bikeonline staff uses the best professional tools on the market into each step of the wheelbuilding process. The P&K Lie truing stand is one example, it allows us to check perfect truing through precise decimal comparators (0.1 millimeters accuracy).
We build most of the tools we use, to fit the level of our builds, which require a high accuracy.
The use of different tensiometers as Park Tool, Pillar and DT Swiss allows us to reach the correct tensions of every spokes.
Each wheel is pre-stressed by hand to ensure that nothing has been settling during the early stages of use and that the spoke tension remains constant for a long time even under very high loads.
This product is to be considered produced on request / on order, due to the high customization needed. It is therefore not possible to use the right of withdrawal or the cancellation of an order already confirmed.
