DUKE ROAD RUNNER 30

The Road Runner 30 rim is a multi-purpose road rim. It will particularly appeal to amateur cyclists who appreciate fine material with its satin black finish, plus as well as a performance design, the Road Runner 30 is rigid, stiff and durable. Available either in a disc braking or standard rim braking version. Tubeless ready or classic clincher & inner tube set up.

DUKE Original Profile

In 2 words, Duke Technology. DUKE is proprietor of the manufacturing tools and processes for its alloy rims and of the moulds for its carbon models. More.

Wide inner rim

A wider profile rim increases the sensation of comfort, for the rider, compared to a similar width tyre mounted on a narrow “standard” rim because of the increased air volume in the tyre. More.

Tubeless Ready

Our Tubeless compatible rims (UST, Tubeless Ready and Notubes), only require some Duke rim tape and a Tubeless-ready valve. They can also be used in a classic clincher set up (tyre & inner tube).More.

Asymmetric (Offset) profile

By offsetting, we can increase the wheel’s lateral strength and its stability without adding weight. Rim drillings are off-centre to improve bracing angles for a stronger, more rigid wheel. More.

- Alloy rim for for Tubeless or standard clincher and inner tube. Designed for a multipurpose use on any road types.
- Available rim profiles: 30mm
- Asymmetric profile: with the appearance of disc brakes and the increase in the number of cassette speeds, the drive side flange is getting “pushed” more and more to the interior of the wheel. This normally causes a reduced lateral stiffness due to the slacker bracing angles that result in slower response and greater susceptibility to the impact of crosswinds. At DUKE, to overcome this phenomenon we have come up with an asymmetric (2mm offset) rear wheel design that gives improved bracing angles compared to symmetric wheels and enables us to obtain better balance between the drive and non-drive side spoke tensions for improved stiffness and durability over the long-term.
- Extra wide 19,5 mm inner rim width. Increases tyre volume improve speed, comfort and grip, especially in the corners.
