Ive had to run my rear brake fairly loose this past year or so (maybe a little longer I cant remember) because I get wheel rub on the brakes during hard efforts. Its not generally an issue most of the year but now its wet and dirty I need more braking power.
Ive checked its not the wheel itself as Ive got another wheelset and both are true and well maintained, as are the brake calipers and pads and cables.
Ive checked there are no cracks in the frame (Focus Cayo carbon) and the QR is done up tight.
Before resigning myself to the probability its just frame flex and I cant do anything about it, is there anything else I should check?
