26" rims for V Brake

Postby Chris S » Thu Jun 19, 2008 7:56 pm

I've just worn out my old front rim, the V brake crushed in half the wall yesterday. I'm now commuting on rear brakes only very tentative.

I've seen a DT Swiss XR 4.1 d wheel up for sale but the 'd' at the end i think indicates for disk use. They did make a rim barke model as well which from what i gather has a wear indicator. Perhaps this is the only difference as the weight is identical other than machined face which could self machine by my pads.
Does anyone know why they might not work on rim brakes rather than disks??

Disk-specific rims tend not to have vertical walls ie. they're curved - so no brake surface.
I don't know about the DT rims, but Mavic and Velocity disk-specific rims can't be used with V-brakes.

i found a site showing section detail of both types and they appear the same, photo of rim i've seen shows a flat face in anodised black. i'm assuming it should be OK.

No. I would not put any faith in a web image. Even a cross-section may not show the differences fully. Disc rims are normally lighter because they don't need a brake surface. They cut weight by making the walls thinner. Put a rim brake on the walls and you'll wear them out a lot quicker than you wore out the first one :(
