However, as Robin was getting a Hardey Spicer shaft for his Box, I thought I'd have one for Chummy as well. They came, with the necessary modifications, from David Cochrane and both fitted without any snags whatsoever. I'm not sure that I can tell any significant improvement in the smoothness of running - but at least the chances of a 2-hour wrestle at the side of the road have been eliminated. At 20-years of age, it would not have mattered, I'd have stuck with the original part (it was all I could afford in any case) but now I take a more pragmatic view.
