IDEA / OFF-ROAD STRENGTH AND LIGHTNESS

Your line
A new advantage

DOLOMITY carbon wheels use asymmetric rim geometry with a −3 mm offset. This adjusts spoke angles towards the hub and helps combine low weight with strength and durability.

Two internal widths, 26 and 31 mm, BOOST axles and two spoke types. Explore the construction, components and all four standard configurations.

IDEA DOLOMITY

The standard IDEA DOLOMITY range combines carbon rims, DT Swiss 350 BOOST hubs and DT Swiss COMPETITION RACE spokes. It focuses on strength, durability, build quality and reliable use with straightforward maintenance.

Lower weight helps acceleration. The final configuration balances quality, performance and price, while allowing individual components to be serviced later.

02 / CARBON RIMS

Asymmetry
for a stronger whole

Two rim widths, with internal dimensions of 26 or 31 mm, share a depth of 20 mm. The new carbon rim structure reduces weight while maintaining strength and durability.

The −3 mm asymmetric geometry optimises spoke angles relative to the hub. M31 and M36 rims are shared by DOLOMITY and DOLOMITY EVO.

IDEA DOLOMITY rims in IDENTITY BLACK design

IDENTITY BLACK

Understated and distinctively IDEA

The unified design combines matt black with a subtle IDEA logo. It complements the bike’s appearance and lets the construction speak for itself.

The graphics also serve as a trademark and are not intended to be removed. An additional marking is inside the rim profile, opposite the valve.

HOOKLESS / COMPATIBILITY

The right tyre
The right pressure

For DOLOMITY the specified tubeless tyre size is 29 × 2.25 and larger, in a hookless-compatible specification. Dimensions follow ETRTO – European Tyre and Rim Technical Organisation.

The geometry supports tubeless setups and conventional inner tubes. Both require a compatible tubeless tyre.

from 1,0 barLow pressure listed for off-road riding

Lower pressure helps the tyre tread find grip. Choose pressure for the terrain, load and specific tyre; the maximum pressure listed for DOLOMITY rims is 4.0 bar.
