This needs huge clarification.
The post is probably not best for this section but thats a minor point.
Ribble are still taking out huge colour double section adverts in Cycling +. so I presume still actively trading?
Unless someone knows different?
Are you telling us that your bike has now a major frame fault that requires probable replacement and you are unable to gain redress with Ribble?
YOu need to persist in contacting Ribble in first instance.
It doesnt matter whether it is their retail or mail order department .. it is the same company??
The frame is cracked NOT due to accidental damage I presume but just to acceptable wear and tear?
Sorry, but as this is a not insignificant supplier of bikes in the UK.. lots of people with Ribble kit.. I personally might have been tempted to purchase at one time...
I think it is now your responsibility to get this matter in the open and kept up to date, as you have aired your grievance on a public forum, otherwise I think this thread should be deleted.
