Bought a Carrera Vengeance from the Trowbridge store only to find on the first ride that some vibration comes from the front wheel when the brake is applied. This has been looked at by the store staff already and the problem remains. Looks like this appears to be a common problem amongst their cycles looking at some other reviews. But this is not the main problem. The main problem is trying to buy a cycling helmet to fit an XL head. Do you think Halfords stock any? Of course not, obviously people only have head sizes up to 61cm, or maybe people with larger head sizes shouldn't be cycling at all. To be fair, this is a common problem in my area with none of my local shops selling cycling helmets in the 61cm+ twilight zone. Could be a good selling point for the company perhaps?
