Ha! I am the friendly windermere bike mechanic..!
Cheers for the heads up on the forum - have since spent a lot of time looking about, and have discovered that another of my old bikes seems to be rare - a yellow and blue raleigh 'team' mtb. I'd not realised it was special! Am in the process of tracking down all the bits, currently one set of cantis short, but many boxes left to go through.. The bane and boon of a barn to store stuff in..
