10 speed rear dropout spacing(4 posts)

10 speed rear dropout spacingACH

What is the rear dropout spread for Campy 10 sp.? Is it the same as 8/9 sp.? I haven't bought a new bike since 88 so I'm clueless on this. Thanks.

Dropout spacings come in 3 different distances:
120 mm (old, old 5-speed and ultra-6's)
126 mm (most 6-speed, and all 7-speed. Common from early 80's to early 90's)
130 mm (all 8,9, and 10 cog rears).
additionally, there is 135 mm (common MTB), and some tandems with even greater spacing.
Not all 7 speeds had 126....Brian B.

Some early 90's seven speeds had 130 mm spacing. I had a Bridgestone RB-2 with that set up, and have heard of a bunch of others, though I can't name 'em right now.

Measure your dropout space, if you have 126mm and your frame is steel, you should be OK. I have Campy 10spd chorus on my frame, and it's 126mm, no problems whatsoever.
