The Black Crow Carbon Dirt Jump rim. Our favourite rims.

32mm external, UST ready

With its 32mm external width, UST design (no rim tape ever) and beefy layup the rims have additional layers to add strength where its needed so you can ride with confidence in your equipment.

We thoroughly tested multiple layups and target rim weights over many months to arrive at the current design.

Each rim is supplied with black brass nipples already pre-installed and ready to lace.  We recommend brass over aluminium nipples for the durability and at barely 20g weight difference per wheel its a no brainier for wheel reliability and longevity.

With every purchase we supply a free magnet and steel nipple insert tool to install any nipples you like through the valve hole (14mm max nipple length).

Lifetime warranty with no BS

The Dirt Jump Black Crow Carbon rim has a lifetime free replacement warranty for the original owner and a transferable crash replacement warranty to consecutive owners if you decide to sell them.

24 hour warranty turn-around

If you manage to crack a rim, no worries, no BS, no confusing process just get in touch, pay the postage for a replacement rim, and it’ll be immediately sent straight out from Australian stock.  No long lead times!

We prioritise any warranty work and make it the most important job in the shop. We aim to have all warranties dealt with within 24 hours because we know how frustrating it is not to ride your bike.

After sale support

Our commitment to you doesn’t end once we’ve got your money. If you have any questions maintaining or servicing your wheels we’re here to help.
