Campagnolo record pista bb

I need bb for campagnolo record pista first gen cranks. English treaded, 120mm rear spacing. Find one bb, on axle is stamped 68-p-110, will it fit or sould i look for 68-p-120? And whats diference bitween 110 and 120 stamped axles? Seller told my that axle lenght of 110 is 109mm, and i know that 120 have 109mm axle too. So whats the diference?

I don't know but perhaps 110 represents the rear hub spacing / spacing of ends of frame that this axle will suit (in terms of the chainline it will give)... and one labelled 120 will suit a 120mm spacing.

This may well be utter bollocks as hubs have the threading for the cog on the shell, and that's not depedant on what spacing the hub is - i.e. a hub can be respaced.

Aha so that diagram shows the chainline on a 68-p-110 is 1.5 mm less than a 68-p-120.

110 represents the rear hub spacing and one labelled 120 will suit a 120mm spacing.

this

And that the axle is 105 not 109.

yah i understand that, i know that axle sould by 105mm..but lots of ebay sellers says that axle is 109mm even if its writen 120...thats why im confused :D

p.s. rive gauche thanx alot, better explanation that i cant expect :D

Umm 109 is BB axle length (well in your case, 105) - 120 refers to the SPACING OF THE HUB not the BB.

OK so the seller was talking rubbish, you knew you wanted 105. Presumably cos you're using a 110 hub.

Rive Gauche gets rep for finding that digram so quickly.

thank classiclightweights :)

i think i should like 'classic lightweight' on my epitaph ;)

Very Good!

120sp would mean 120mm rear dropouts suitable for pista or strada

some older pista frames had 110mm rear ends

Dredging up an old thread, but looking for some help finding cranks for my friend's Mercier. He has a Campy BB with 68-P-110 printed on the axle

Backstory:
My friend Nico's pink Mercier has French threaded bottom bracket which had a VO cartridge bottom bracket with French cups. The threads on this were mashed. We retapped the bottom bracket and Nico got a NOS Campagnolo French threaded BB. The description was 69-P-110 on the axle. He thought this meant it was 110mm long, in fact the above diagram shows that it is infact 105mm. I think it is JIS taper.

Anyone have information on what crankset we could use to set it up as a single speed. I believe the rear spacing is 126mm. I realise this probably won't result in perfect chainline, using a 120mm fixed wheel and spacers, but due to the cost and rarity of BB with french cups it would be good to know what we should be looking for.
