Campag specialists out there......

I've just returned from a cycle jumble in Manchester ....bagging myself a couple of bargains......one of which is a 151 bcd 53 tooth chainwheel in good usable condition, but what is noticible is the little screw in pip [or whatever it's called] to prevent the chain falling down the inside of the crank!

Now I always thought this was a later addition to the 144 bcd chainwheels.....as in the early 144 bcd chainwheels didn't have the pip?

So the question is.....How come Campag introduced this feature on the 151 bcd chainset....only to drop it when they brought out the 144 bcd chainset.......but then reintroduced it a while later?

It does seem to me Campag where a bit inconsistant with certain features.......for example with the Record and Cobalto brakes.......unless I'm mistaken it seems the Cobalto had steel brake pad holders, wheras the Super Record [ or some of them] had alloy pad holders, and alloy adjusters..............

One final titbit.....recently there was some chat regarding the 'outside bearing rear Gran Sport hub' many remarked about the pitfalls of such a design.........I have such a hub, though have yet to ride the bike with it on, so can't report on it's function........you don't see that many...but today there was two for sale today at the jumble!

Right, time to have another glass of Tuscany wine and fondle my new found Campag!
