Zeus Pista 1970/80's - "Poor mans Campagnolo" + "Lava Lo-Pro"

I haven't got that far yet, but will look through some catalogues and see if I can find any info on the threading as its late and should go to bed. But I read somewhere it should be italian or french?
Yeah, think it might be French. the cranks on mine have been re tapped to take the usual 9/16 threaded pedals, but if youve already got your hands on Zeus pedals then youve nothing to worry about.

The crankarm bolts look to be a special size compared to a few others, but haven't got round to fitting either.
Yeah, i think so. What happens is that once you inset them, there's not enough space between the edges of the head of the bolt and the surrounding hole in the crank arm to get a normal socket wrench in there.
Zeus used to have theyre own tool for doing this apparently. A few of the more decent bike shops here in Spain have home made tools for this very purpose; basically a socket thats been pared down to fit into that tiny gap. Alternatively you can just switch it for the correct sized Allen bolt, but since youve got the bolts already (and even the bolts alone go for a few quid these days!), maybe your next project will be DIY tool making.... good luck!

How many holes do your hubs have? Let me know if you ever decide to sell the wheels off might be interested.
Will have to check the no of holes. Will let you know if i flog them, as Im considering it, but the threads on the rear hub arent in great nick..
