Not just Campagnolo but rather all hubs: Five are 120, six 126 with standard FW. With 'suntour ultra' freewheels 120 is six With non-suntour-ultra freewheels, six is 126mm. With all freewheels, seven is 126 mm 5 / ultra-6 120mm ~ 23 mm of freewheel space (5.3 * 4 + 1.85) 6 / 7 126mm ~ 30 mm of freewheel space (5.0 * 5 + 1.85) 8-speed 126+ ~ 31.5 mm of freewheel space (4.8 * 6 + 2.00) (sachs made 8-speed freewheels - but axle failures were very common) A great source for understanding freewheel and cassette spacing is Sheldon Brown's "sprocket spacing" tables : http://www.sheldonbrown.com/k7.html Perhaps the most important things to remember is that cog widths didn't change noticeably (~1.8 - 2.0mm) from 5-speed to 10-speed (EXCEPT for shimano 10-speed, 1.6mm) - the spacers have simply been getting thinner and the sides of chains have been getting flatter, so that more cogs can be squeezed into the same amount of space. - Don Gillies San Diego, CA |
