ROCKYROAD 25C DISC Clincher Tubeless Ready
UD carbon, matt finish with shiny decals
Hooked design rim, allows the use of tubeless ready tires or standard clincher tires with tubes
Internal width: 19mm
The special layering of the 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.
Asymmetric design: ensures a significant increase of stability and lateral stiffness of the wheel thanks to a more balanced spoke tension between the two sides of the wheel
Tubeless ready: tubeless convertible with specific tape and valves
ROCKYROAD 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.
ROCKYROAD rims are intended for Road
Crash replacement policy: in case of accidental break of a ROCKY rim, not covered by warranty.

BERD POLYLIGHT SPOKES
Berd spokes are made from an advanced polymer called ultra high molecular weight polyethylene (UHMWPE) that has 12 times the strength-to-weight ratio of steel and floats on water. Berd spokes have an improved fatigue life compared to steel and are impervious to the elements.
Berd spokes use 14 gauge threads to connect to standard nipples the same way metal spokes do. Opposite the threads is a loop, which is pulled through the hub hole and secured with a rod. Berd spokes feature a 1.8mm diameter in the mid-span and are 2.5 grams per spoke.
Advantages of BERD PolyLight spokes:
- the weight of 2.5g allows to save almost 70/80 grams compared to the Alpina HyperLite spokes, that are the lightest steel spokes available on the market
- 12 times the strength-to-weight ratio of steel
- Berd spokes also damp vibrations much more effectively than steel spokes. This results in a more comfortable, smoother, ride. Berd spokes provide 200% better vibration damping than metal spokes.
The UCI, which regulates professional cycling, has specifically approved Berd spokes, so you can race Berd spokes from local crits to the Tour de France.

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.
