CURVE Dirt Hoops Carbon
Hoops for Dirt
Our 29" wheels have a reputation for taking riders on some grand adventures, from XC sprints to 5,000 km expeditions. With our Dirt Hoops, we've combined excellence from our previous off-road wheels with new technology to bring you wheels that outperform in the burgeoning worlds of dirt riding and racing.

Hubs: DT Swiss 350 28H/28H Spokes: Sapim CX-Ray Nipples: Sapim Polyax Secure Lock, Brass, 14 mm Standard builds use Straight Pull Centrelock hubs. Dynamo builds use J-Bend 6-bolt hubs. |
Moulded spoke hole technology allows us to reinforce the spoke hole and nipple bed area yet reduce the bulk of unnecessary material in between spoke holes. The result is a light rim, with no compromise on strength.
Chunky Hookless Bead
We’ve increased the impact strength of our hookless rims by widening the Dirt Hoops hookless bead with a chunky 5mm foundation.
Tubeless Ready
Tubeless tyres for bicycles have been one of the greatest improvements to overall ride quality and reliability. Setting your Dirt Hoops up tubeless will help reduce pinch flats and punctures, decrease rolling resistance and increase control.
DT Swiss hubs & Sapim CX-Ray spokes
Our favourite hub/spoke combination, the DT Swiss 350 Centre Lock Straight Pull hub and Sapim CX-Ray Aero Bladed spoke. It is a fine example of a balance between weight, reliability and performance when paired with Curve rims. This combination has proven itself time and again under the harshest conditions and treatment, we can throw at it.
What else?
Dirt Hoops wheelsets arrive tubeless-ready, with tubeless rim tape, valves and centre-lock rotor lockings. Simply install tubeless-ready tyres, sealant and inflate with a tubeless floor pump (In most cases a compressor is unnecessary). Then go ride!
FAQs
|
What tyres can I run? |
So many choices! A 25 mm internal rim typically works well within a range of tyre sizes from 28 mm - 50 mm. A 30mm internal rim typically works well within a range of tyre sizes from 50 mm and beyond. Some narrower tyres on wider rims will square off too much, and some wider tyres on narrower rims will fold and squirm due to lack of sidewall support. |
|
Which Rim Width Should I Pick? |
If you're after a Gravel wheel and don't see yourself running a tyre larger than 45 mm, go for the "Wide 35" version (25mm internal). If your riding is a bit more chunky gravel or XC and you're looking to run tyres 45 mm and beyond, we recommend to go for the "Wider 40" (30mm internal) version. |
|
Why brass nipples? |
Although brass nipples are slightly heavier than alloy nipples, they are far less likely to suffer corrosion and premature failure. They are durable, serviceable and ideal for extended usage |
|
Can I customise the build? |
Definitely. Dirt Hoops are available as a rim-only option. You can then configure your wheels any way you want. As long as your hubs of choice are 28h. |
|
Why only 28h? |
We believe 28h is ideal for most off-road applications. Through a custom build, you can obtain a competitive lightweight XC configuration up to super robust expedition strength wheels. |
|
What tyre pressure to run? |
We get this question a lot! Follow the guide on your tyre and have fun experimenting +/- a few PSIs for feel. The tyre should feel responsive, provide ample grip and be hard enough to not bottom out the tyre on the rim on rocky terrain. Lighter riders can afford to run slightly lower pressures, whereas heavier riders should err towards recommended pressures. Narrower (low volume) tyres will need to be run at higher pressures than higher volume tyres. That said, we do not recommend exceeding 35psi for any tyre that would be suitable for this rim. |
