This is the XPX donor I bought to build up the 857 frame, I took it for a 10 miler today just to check it all worked after replacing the elastomers with coils before stripping it down and besides a dodgy pedal it's brilliant.
Just too big :cry: hence the low seat post.
Got my Hammerhead rear disc adapter through today and after all the mucking about with other types have to say its THE solution for anyone who wants to fit discs.
If you're looking for one then give Mike at www.racing-green.com a shout as he can supply for x55 x56 x57 series.
