After returning from a 50 miler today, I parked up and checked the bike over. It appears that I can now squeeze the rear brake lever about an inch before I get any resistance at all (from the cable).
I've had the bike about three months, and the rear lever always rattled, but I thought it was due to them being a fairly basic set. Now it's rattling a lot more. I guess there might be something to tighten or adjust, but I've no idea where I might start looking.
Anyone have any idea?
