I have emailed Boardman so will see what they say. As I'm the second owner I know they have no liability to me. If the seller returns my email I might see if he will help me out. But I suppose it is bad luck, just not what I expected from a bicycle a few years old, little ridden, excellent condition. This is the 'best' bicycle I've ever bought so I wasn't expecting structural failure. I bought this based on so many reviews raving about the quality of the Boardman bicycles so it is a pity to have this experience.
If Boardman don't do anything then I will have to buy forks. Thank you
@Afnug for the information about the crown race. Frankly if they need replacing I'll get a bike shop to do it for me if there is anything technical or time consuming as I am so busy at the moment and don't want to make a mistake or order the wrong thing.
On the good side, at least it happened now before our year away and was in a flat garden at slow speed rather than a fast descent with a trailer behind!
