Curve Dirt Hoops

INTRODUCING OUR STRONGEST OFF-ROAD CARBON WHEELS YET!

Choose your own adventure - MTB, Gravel, Off-Road Touring Adventures, Mega Expeditions, Bike Packing, Basket Packing, Beard Packing - Whatever spins your wheels our DIRT HOOPS will carry you through! 

Our 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 out-perform in the burgeoning worlds of dirt riding and racing


Mo-Spo Tech

Moulded spoke hole technology allows us to reinforce the spoke hole and nipple bed area yet reduce the bulk of unnecessary material inbetween 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

We continue to use 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 25mm internal rim typically works well within a range of tyres from 1.75" - 2.5" (44mm - 64mm) A 30mm internal rim typically works well within a range of tyres from 2.3" - 3" (58mm to 76mm) 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. This is more common at the extremes (eg a knobby 44mm on 25mm internal width)

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 rim only. 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 Weight Weenie-ish XC configurations up to super robust expedition strength wheels.

What Tyre Pressure to Run?

Wow... We get asked this so often and we don't even manufacture tyres. Follow the guide on your tyre and have fun experimenting +/- a few PSI's for feel.

What does "ERD" and "Spoke L. F&R NDS & DS" mean?

These secret codes are for the wheel illuminati. ERD stands for Effective Rim Diameter, measured at the spoke hole (external).
"Spoke L. F&R NDS & DS" is the "Length" of spoke for the "Front" and "Rear" "Non-Drive Side" and "Drive Side"
