Black anodised non deep section rims, where to get them?

Quite a large choice of disc 29er rims which are still light (as intended for XC). Afew mentioned above.

They do look bulkier than road rims though but good if you plan to run a wider tyre or fancy something a bit burlier.

Need to be careful about the internal width (bead width) though. The 700C VXC are thin 29er rims really, but have a inner width of around 21mm so should be good to go for road tyres.

But yeah, alot of XC 29 rims would work.
