Hey all, i managed to get a 203mm rear BB7 for my 24uk about 2 weeks ago, i fitted it and bedded it in using the hill/ water technique, and it works amazing. However, when ever i leave my bike in the garage overnight, by the morning it has no hold, no bike and just feels horrid. I can get it working again by putting water on the disk, and riding around for a bit, but i want it to work constantly like my front BB7 does. Has anyone got any suggestions/ ideas as to what is causing this? All help appreciated, Chris x
