Brand New DT Swiss 350 QR Rear hub in black, with a DT Swiss 240s Sticker. Centrelock (but can be made 6 bolt with an adaptor), 28 hole so ideal for a nice carbon wheel build and at 273g on my scales it's only a few grams heavier than a DT 240.
DT 350 hubs have the same star ratchet and thus buletproof reliability of the DT 240/180/190 and use all the same axles and endcaps so it is very versatile.
I was unwittingly sold this via ebay as a bit of a pup and as I've just sold a DT 350 to buy a DT 240 hub my search goes on. For all intents and purposes it looks like a DT 240. Still yours for a pretty price though.
RRP is around £180, looking for £90
