I upgraded my Rockhopper Expert with a 11 Reba XX from a Dart 3. So far awsome fork. One problem I keep having is that my front wheel keeps coming loss. It doesn't matter if I crank it tight or just snug it. (9mm QR). I went to lbs and got another on and it did the same thing. I just ordered a DT Swiss 9mm thru( Steel & composite) to try and stiffen it up but most importantly not lossen up. Any other Ideas. Never had this problem with my dart front wheel, wheel is put on and off daily. I would like to resolve this before my 203 brakes come in so I don't end up messing them up.
