Carrera bike purchase ! Had bike built my them - ten months passed and fairly trouble free until this month when strange squeaking was coming from crank , called Halfords and booked in - day off work and went to local store and they said it had two light buckles in both wheels , rear wheel bearing and poss bearings in crank ! Said I had to re-book for a repair and take bike with me and bring back again! All this was classed as wear and tear . Had gears adjusted and today the chain dropped behind rear cassette.was rudely treated on online chat and cut off after 35 mins on phone .
