So the postman brought my new Ebay purchase today:

Campagnolo Super Record crankset

170mm Strada time trial crank, for single chainring. Made in 1981

47 tooth chainring (and a 53 I shall not use)

FAG Nadax sealed BB with short titanium axle. I’m not even sure my rear stays will allow an axle this narrow.

Suntour Superbe Pro pedals
So that’s a very nice bit of kit for starters, but there is more than meets the eye:

This crankset was used by Ken Bird – Tommy Simpson’s mechanic. He countersunk the chainring bolts so that they don’t spin. So you don’t need the Campag spanner on the back to change the ring – just an allen key.

And what is this? “SY” painted on the chainring in red nail varnish. That’s because the previous owner of this chainring was Sean Yates. How cool is that? He’s left it in very good condition. Thanks Sean!
