Hi, Ive got a Bianchi Via Nirone 7 2011. The front brake, snapped while I was out today, it sheared the bolt that connects the calipers. I have been to Evans - 'Run by cyclists for cyclists' I do not agree with that. They assured me they were selling me a FRONT RALEIGH BRAKE but they couldnt fit it. I took it to Harry Halls and was advised it was a rear brake, now looking at the the Raleigh rear and 105 front I cant spot any difference? Is there any?
