Can anyone out there with a Quaife gearbox give feedback. There is one on e-bay and I have been considering placing a bid BUT am unsure what advantages it will bring. I have a B Rapide with 8:1 pistons, BT-H ignition and home-made cams that have more overlap than a Shadow but less than a Lightning (similar to 105 cams ?). At the moment I have a 48T rear sprocket to cope with the local hills but would like to fit a 46T and still have the "grunt" for the hills.
