Description

Rim features:
ROCKYROAD 39C DISC Hookless Tubeless Ready

UD carbon, matt finish with shiny decals
Height: 38mm
Width: 25mm
Internal width: 21mm
Weight: 350g

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.
Hookless: no bead hook on the internal sidewall, it allows to position the carbon fibres in a continuous manner, without interruptions that would jeopardize the strenght in a part of the rim that's one of the stressed. WARNING: Hookless rims require the use of Tubeless Ready tires only, with or without tubes. Refer to the instruction manual of the tire manufacturer to verify compatibility with hookless rims.
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 use.

Crash replacement policy: in case of accidental break of a ROCKY rim, not covered by warranty.

Hub features:
DT SWISS 240 EXP SP (Straight Pull) Center Lock
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.

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.
