Curve Alloy Dirt Hoops

These super wide alloy rims are ready for your next off-road Adventure. Whether you're shredding trails or rugged multi-day touring, Curve's Dirt Hoops Alloy wheels are built tough to party hard and ride harder.

Dirt Hoops but now ALLOY!

Shredding singletrack? Epic off-road continent crossing adventure? The dirt hoop alloy is a wheelset that fears nothing, and will happily take you to every corner of the globe, no matter how gnarly the terrain!

Takes all the pluses of the carbon dirt hoops and constructed them from alloy - that remains lightweight, affordable and dependable! Your glorious guide across all terrains.

Wide Alloy

With 30mm internal rim width, you can accomodate tires from 2.2" right through to 3.0" to suit a variety of off-road needs, and arm you with bags of confidence!

Tubeless Ready

Tubeless is now the standard on all Curve wheels, so your fresh new Dirt Hoops Alloy wheelset will arrive tubeless-ready. Equipped with tape and tubeless valves. Simply add your gnarly tyre of choice, throw in some sealant, and inflate. It should seat with minimal fuss and you're ready to hit the trails!

DT 350 hubs

DT Swiss 350s are the hub of choice for all Curve's wheelsets - chosen for their performance, durability and serviceability. Combine with the Sapim CX ray spokes, and you have a super strong wheelset, that doesn't compromise on weight either! Tried and tested by the Curve crew themselves under some of the harshest conditions!

Optional Dynamo Power

Adventure is in the blood of the Curve crew, so a dynamo option on this Alloy wheelset was a no brainer. Keep lights and devices charged whilst out in the wilderness for many days, it's a simple addition for the Curve crew to spec, so just let us know! They use the trusted SP Dynamo, which will never leave you powerless!

What Tyres Can I Run?

So many choices! A 30mm internal rim typically works well within a range of tyres from 2.2" - 3.0" 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 and varies from tyre model to model.

Why only 28h?

We believe 28H is ideal for most off-road applications, as we've seen from our real world testing from XC racing to off-road touring.

Can I Customise the Build?

Definitely. Dirt Hoops Alloy are available as rim only. You can then configure your wheels any way you want, as long as your hubs of choice are 28h. Get in touch to discuss your options.
