ROCKY KOM 29C BERD 29er / ROCKY Boost SP carbon MTB wheelset 1.150g

ROCKY KOM 29C carbon rims represent the evolution of our range and take advantage of the latest production technologies and the finest materials.
The 29mm 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.
The new paintless finish, adds no weight and makes the surface much more scratch resistant.

Rims: ROCKY KOM 29C 29er, inner width 29mm, 300g.
Hubs: ROCKY Boost SP: 144g + 217g.
Spokes: Berd Polylight
Nipples: Pillar DSN ergal.

Maximum bike system weight: 110kg (rider, bike, clothing and backpack / bags)

Wheelset weight: 1.150g. (Berd Polylight spokes).

The sales kit includes:
- ROCKY KOM 29C / ROCKY SP Boost MTB wheelset.
- 2 Berd Polylight spokes.
- 2 spare DSN nipples.
- Tubeless tape installed.
- Barbieri Carbonaria valves installed.

Description

Rim features:
ROCKY KOM 29C 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 29mm 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.

Spoke features:
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.
Made in USA

Every wheelset is supplied with 2 spare spokes/nipples

Nipples: DSN ergal
Not supplied with quick releases

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.
