Campagnolo record pista bb

... Seller told my that axle lenght of 110 is 109mm, and i know that 120 have 109mm axle too. So whats the diference?

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

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.
