Had enough of the utterly chronic Sachs rear unit, so after ALOT of research I have bought a Maxton RT10. Not fitted yet, hopefully that will be done tomorrow. It looks superb though, extremely well made. In the end there wasn't much choice, apart from Maxton, there was Nitron, Bitubo or Ohlins, that I could find. Nitron were a bit vague on whether they had the correct info for my bike, I couldn't get a quote out of Bitubo and Ohlins is just silly money. Maxton have a top rep in the UK for race success and really know what they are talking about. I'll be getting the cartridge fork conversion from them next year too.
