Again, thanks for the input. The axle from an S4r looks like the one for these forks, I'll have to measure up again and check. The S2r calipers are the wrong ones as Darren69 mentioned, again the S4r calipers appear correct.
The mudguard is different as well as you say Darren, so I will have to source that along with a speedo drive, As Flip said I hope there are some cable driven ones around.
