My knees have been playing up quite a lot recently. I jumped off my bike earlier and landed on it funny. The pains stopped now but I couldn't carry on riding this evening

I don't know anyone from York besides Danny Garland that rides trials.
David Logan from Leeds used to have a Skye. I'll ask if he sold it to someone from York for you.
Just been to the skip with a load of cracked/snapped/useless parts (mainly Echo!) and a load of tyres. Felt good getting rid of it all!
Sorted my bikes out too ready for summer!
