Pedals Campagnolo Super Record track pedals with Christophe toeclips.
Gears Huret rear derailleur with drilled cages.(Apparently these are slightly heavier than the undrilled version, because of the strengthening needed on the drilled cages) with Suntour Winner six-speed free wheel

Extra details Alf was one of the early English riders to start drilling and milling components to reduce weight, insist on super short-wheelbase frames, and 'man-sized' big chainrings, all of which Alan Shorter was happy to supply.  The finished bike, ready to ride was only 8.6 kg's.  Alan Shorter would have been proud.

Ever since I picked up this old set of drilled and chopped universal brake calipers I have wanted to put together a
replica of Alf's pink Shorter TT bike, so I was really pleased to find one here in New Zealand.
