What are my exact consumer rights here? About eight weeks ago, I bought a Giant Defy disc brake bike from a big bike shop. Initially, I assumed it would be great and was very enthusiastic about it but things have changed quite a lot since then. I've had it in the shop (54 miles from home incidentally) three times since purchase. Firstly, the head thing was leaking brake fluid so that needed rectifying. Then I took it in last week due to a combination of it not shifting from the big to the little ring and an 8-week tinkle. I assumed it would be done the same day but no, it was a day later, necessitating yet another 108 mile round trip to collect it. But now all would be well, wouldn't it? Well, no actually The very day after the mechanics had re-set it, I took it on a hilly ride in the Yorkshire Dales. It wouldn't shift back from the small ring to the large one whatever I did and I'm no novice at cycling so I know how to rectify this sort of thing but this was to no avail. This bike has a 13/32 cassette on the back so that was going to help me on the climb over Fleet Moss...except it wouldn't go near anything over 27! At the steepest point, I tried to drop it into the 30 or the 32 but it wouldn't go even with the shifter pushed as far over as it would go. So I called the shop explaining my predicament to be asked to bring it back in - I took it in yesterday, another 108 miles and was asked to collect it today or tomorrow - another 108 mile round trip! I was informed 'you sometimes get this with Ultegra' like it's only to be expected! The manager also informs me he'll take it up a hill but he'll have to go a long way to find anything that could test it like Fleet Moss so I can't see any way he'll replicate the necessity for a 34/32 combination under the stresses needed. I mean, you don't pay £2,000 for this aggravation do you?
