ROCKY KOM 25A 29er / DT Swiss 350 SP aluminium MTB wheelset from 1.390g

The ROCKY KOM 25A rims are produced using an aerospace aluminum alloy 20% more resistant and more rigid than the best aluminum alloy used for rims.
This allows to obtain lighter rims, with superior mechanical characteristics.

Description

The ROCKY KOM 25A rims close the performance gap between a carbon and an aluminum, with a low weight that's competitive with most carbon rims with these dimensions.
Our aluminum alloy is produced and drawn in Germany and wisely worked in Italy, where the rim is created by a straight bar, then subjected to the Shot Peening process which reduces the surface tensions of the material due to the processing, improving fatigue resistance and durability, and finally anodized and laser etched.

Rim features:
ROCKY KOM 25A 29er
The Climber XC is built for cross country.
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, not included in the sales kit.
Matt black anodized aluminium 6000 T6
Aeronautic Surface Treatment (AST) eliminates surface tensions of the material, increasing the resistance.
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.
Hookles design
Suggested tubeless tape width: 26/27mm
Max pressure: 3.0 Bar
Tubeless ready
Height: 18mm
Width: 28mm
Internal width: 25mm
Number of spokes: 28

Hubs features:
DT SWISS 350 SP (Straight Pull)
Difficult internal structure and sophisitcated milling-jobs on the outside structure were necessary to finalize these hubs. The hub-body is oversized and at the same time very light. The spoke holes are drilled with 3D angles in order to give the spokes a direction for 3.5 X lacing. We offer various conversion-kits to make the hubs compatible to fit to all major standards.
The hub body is made from forged 7075 T6 material - just a few manufacturers forge the hubshells with this material in order to get the maximum strengh out of the hubshell.
All other hub parts, such as the axles, the freewheel body and the sidecaps are made from 7075 T6 material as well.
The front and the rear axle have a diameter of 17mm at the bearing seats. Weight reductions were realized by removing axle material on the outside structure where it is not needed.
Another feature of our hubs are the anodized axles, which prevent from oxidation and corrosion.
The freewheelbody has 3 pawls, the gear-ring has 24 teeth. This configuration ensures a hub drive system which lasts. 24 engagements is a reliable choice which will still work after a certain usage, even the teeth and the gear-ring show a little bit wear. Other manufacturers strive for excessive engagement points. Due to the micro structure of the gear-ring and pawls, these systems tend to wear out quite fast and fail to work even just a little bit of water gets into the hub.

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.
See "Terms and conditions of use". Advance payment is required on this product.
