I've just bought a pair of Mavic Crossmax from a member here, so the pair of wheels I was going to build myself is no longer required.
For sale then, is a pair of unused DT Swiss E540 rims.
These are a disc only enduro rim, anodised in black with silver chrome spoke eyelets. Not the lightest on the market, but light enough, with plenty of strength.
Specs are as follows;
Profile Width: 27.9mm
Rim Joint: Sleeve Joint
The cheapest I have found these rims online is at bike plus.co.uk, where they have them reduced from £54.99 each to £27.49 each (plus shipping). So, these are on offer to Retroride members for £45 for the pair inc. postage in the UK.
