In other news all the parts I needed arrived to convert my 10 speed Mk3 Touring to 11 speed, whilst retaining the high speed 9t cog. More to come unless anyone has posted about this before. Have 2 cassettes a 36-9 which is super wide range and a 32-9 which is the same range as the 10speed touring but with an extra close ratio.
Is anyone interested in the story once it's built?
