    Campagnolo 8 speed Rear Mech with 10 speed cassette

    I expect you'd have shifting issues with that combination, 10sp shifter n'all. (Although I've never tried it with Campag.) I've just built a Corsa Extra. New type Campag freehub (same as you will have), new 9sp rings, 9sp cassette and chain working with the old mechs, shifters and cranks...

    Merckx Corsa Extra internal cable routing

    Thanks all, I got some stepped ferrules. For 5mm brake cable outer stepped down to 3.7mm outer diameter to fit into the frame. It was a little loose so I wrapped some heatshrink sleeving and some electrical tape to make the ferrules fit snug. Anyway bike built now and rear brake working...

    Merckx Corsa Extra internal cable routing

    Thanks Jamie, I think my Corsa Extra frame is slightly different, the recessed cable hole is not more than 2.5mm diameter. I guess your frame has a larger hole to enable you to feed the Shimano sleeving all the way through? Wish mine was the same! Had another go with last night with more...

    Merckx Corsa Extra internal cable routing

    I've invested in a beautiful new Campagnolo cable set but the rear brake cable has too much friction through the internal cable route in the top tube so the calliper's not releasing. Only the inner cable passes through the very small cable route hole. I've tried cleaning out the channel with...

    Merckx - Campagnolo 8sp

    Thanks again, showing my newbness! I have a Chorus double crankset from 1991 so I've learned that it will have the pre-ISO Campagnolo taper which is a bit like JIS (but not quite) . :roll: Would a new Centaur 111mm BB fit? because it states on the Centaur spec: "Also fits 1993 and...

    Merckx - Campagnolo 8sp

    Just been through this analysis myself. The 8sp shift sprocket to sprocket is 5mm. 9sp sprockets are 1.75mm thick so you need 3.25mm spacers to make a 9sp sprocket correct for 8sp. But you'll also need 1.25mm of packing spacers behind the cassette to make up the length on the hub body (38mm)...

    Merckx - Campagnolo 8sp

    Sorry to say, I'm faced with a grinding 18% outside my door. Nevertheless I'm just hoping that it will shift and run nicely with this Franken-Cassette thing I'm planning to do!

    Merckx - Campagnolo 8sp

    Thanks for the tips hamster/monty, much appreciated. So is it reasonable to get factory Ambrosio Evolution wheels with Campag hub and a stock Veloce 9sp 13-28 cassette. Lose the 28t sprocket for 13-25 (I live in the hills) and make it fit using the correct spacers? Would a Chorus short/long...

    Merckx - Campagnolo 8sp

    Rightly or wrongly! I decided to seek retro Campag Chorus 8sp parts for my Merckx Corsa Extra frame rebuilding from scratch. In order to get up and riding quickly, I was hoping to get new wheels but then learned the Campag 8 cassettes don't fit on newer Campag hubs. I'm attracted to the...
