Not got dirty yet mate, my lady hasn't ridden a bike off road before so I'm taking it easy with her so as not to put her off! It really is in fantastic condition though, it looks new and has full XT now too.
I did mention retrobike mate yes! The guy that helped me was really sound and we got onto the topic of old mtb's while chatting away. He didn't know about the site but said he was after a retro Roberts d.o.g.s. b.o.l.o.x. so he might well be joining up in the near future!
Thanks again matey my lady is really happy with it!
