I think I am going to struggle to make this ride, am having to many issues with my bike just now..doing the lepra ride my rear tyre exploded, got a new armadillo tyre on Monday, went for a ride on Monday night everything was fine, then I planned on doing a 70 mile ride on Tuesday at about the 40 mile mark I could hear a noise coming from my tyre that sounded like my tyre was flat yet it wasn't, I got the girlfriend to pick me up, as I was putting the bike in the van I noticed that my rear tyre had a bubble on it, the bubble was on the ridge of the tyre the part that is always on contact with the road, the bubble was about 1cm wide and about 10cm long, I thought it was maybe the tyre was faulty so I took it back to the shop and they were happy to replace the tyre, so I get home and change the tyre, I puncture the tube when am changing the tyre lucky I had a few spare tubes, so I replace the tube, I inflate the tyre sit it against my bike and the bloody thing explodes, that's another new tyre wrecked... So far in the last couple of weeks I've went through 3 rear tyre and about 5 tubes.....this bike is costing me a fortune and on top of all that I've still got this horrible clicking noise when I put pressure in the pedals......if I can get everything fixed I will be there but only if my bike is perfect its to far to take a risk with a bike that isn't 100%
