So, I’m plodding round my final lap at SITS yesterday when I notice I’ve ripped the rear tyre and the tube is bulging out. 5 mins later it’s exploded with such a bang its cleared the woods of all bird life.
No worries I think, I’ll whip the tyre off and make a boot out of the cardboard box the spare tube is in. That will get me home.
Epic fail… DT Swiss QR has failed. I take it apart to discover it works on a ratchet system. One cog is metal, the other is plastic. The plastic has disintegrated so it just spins. I’m walking the 4.5 miles to the finish line… Thanks to all those who passed me and offered help BTW.
Doesn’t look like you can just buy a new plastic lever (don’t suppose anyone has one going spare?), you need to buy the axle set 🙁
Just done a google search and it appears this is quite a common fault. Apparently the damage is caused by overtightening. Well, given that the rear wheel fell out twice when I initially got them, yes I now make sure it’s nipped up.
An unhappy finish to an otherwise brilliant weekend. If you have DT Swiss QR’s, it might be worth undoing the allen key bolt and having a look at the plastic bit. If this had happenned in the Lakes, miles from civilisation I’d have been mighty p1ssed.
