This is a bit of an odd one. I'm building a CX bike for which I have two wheelsets; a freehub/tubular set and a freewheel/clincher set. I will use a Shimano HG-50 8 speed cassette on the tubular set. I have an 12-24 8 speed Sachs freewheel, which I assumed would index perfectly with my planned setup, but having just seen
this I'm unsure.
It seems the Sachs 8 speed freewheels used Campagnognolo 8 speed spacing until 1998 when they began to use Shimano/SRAM 8 speed spacing. I'm not sure if I could tell the difference by looking or even measuring with a caliper. Maybe I can, but if there's an easy way to date these freewheels then that can only help. The freewheel I have does not have Shimano/SRAM ramped (Hyperglide) cogs, but rather the notched teeth.
Anyone know?
