Hi Rick -

This is all true, I realised my maths was up the spout after I'd written that...

Certainly lowering the gearing causes the speedo to over read even further, although for anyone interested, once you fit an 18 inch rear wheel, I'd say the stock gearing would be pretty much bang-on - I am running 15/46 with the 18 inch rim and it only over-reads by a couple of miles per hour now...

Of course the 18 inch rim also has had the effect of gearing it higher, so i will be needing that 48T rear sprocket after all, just to get it back to somewhere near normal!
