    Campy 8 sp gearing Options - how low can you go and stay campy?

    What's the lowest gearing I can get with campy ergo 8 speed? Can the rear mech handle a 28t? Can I even find a 8 speed cassette in 28t that works with campy indexing?

    I'm running 53/39 in the front. I'd like to run a 28 tooth cog in the rear but it looks like I might be stuck with 26. I have not purchased a rear derailleur yet but I wanted to stick with campy.
    Mmmm, bicycles.

    I know Miche makes a 13-28 cassette for campy 8 speed. I don't know any campy 8 speed derailleurs will work with 28t cog. My guess is, it will probably work.

    +1, I think abarth is correct.

    The chain tension should pull it down far enough to clear.
    The only problem I see is on the small ring, 28t cog, with possible coziness of the upper pulley and cog.
    I still think it will work. I'll check my Chorus and guesstimate.

    The 97 Bianchi Trofeo came with Miche cassettes, and I think the double had a 26t low gear.
    I wouldn't be surprised if it goes 28t (Avanti).

    I have a Racing-T rear that looks like it can handle 28 easily.

    Bump. I'm interested too. I'd like to get my hands on some Ergopower stuff to try out this new fangled integrated shifter/brake lever mess.

    looks like the Miche campy splined 8sp 28t cassette is the way to go. I can only find one place that has it though, and it's in the UK. Anyone have any more local leads on where to get these?

    You don't say what type of RD you would consider, but if you are willing to go modern, you can get a medium or long cage modern 10 speed RD and it will index with 8 speed, or a 7 speed freewheel, for that matter. I do this with a long cage and a 34T on my wife's bike, and a medium cage on a 28T on one of my bikes. A 7 speed freewheel opens a lot more possibilities.

    Yes, I use 9 speed chain, but 8 speed works on my wife's bike. I don't know whether this affects an 8 speed crank, as my cranks are ten speed also.

    explain this please. How will a 10 sp mech index with my 8 speed stuff? Will it just have two extra clicks that dont do anything assuming I set the limit screws for my 8 speed cassette? This is an option I'd consider as I didnt realize this would work....

    There are no clicks on a rear derailleur. It's just a matter of the throw, and it has plenty.

    I use 8 Speed Ergo's so I can keep my stock wheels with a 7 Speed freewheel. I use a ten speed derailleur for two reasons: 1) It's brand new so I don't have to worry about banged up or a glitchy RD, and 2) it's easy to find a long cage derailleur, unlike with old Campy stuff.

    I've used Veloce and Chorus RD. The Chorus is a little more picky about the chain, as OFG mentions.

    It doesn't look vintage, but RD's hang out in space, waiting fro the bike to fall or lean against something. I hate crappy shifting, so I won't waste my time with used derailleurs. I want something I _know_ is perfect.

    oh right, the clicks are in the shifter. I didnt completely think that through.

    So you're saying an 8 speed ergo will index correctly on top of a 7 spd freewheel? Now in that case there would be an extra click yes? I'd need to run a different wheel since I can't put a 7 sp freewheel on my campy 8 sp hub though, right?

    Correct me if I'm wrong, but starting with the "next generation" 9 speed stuff (rounded ergo lever hoods + screened on '9 Speed' label) the actuation ratio was changed. So, 8 speed ergos might not mesh perfectly with a 10 speed RD. My guess is it might work well for a while, but as things wear, you might begin to experience shifting trouble? Maybe I'm completely wrong, because I know things that aren't supposed to work often do.

    But yes, 8 speed spacing on a Campy cassette is identical to Shimano 7 speed spacing, so you can use a Shimano compatible 7 speed cassette with 8 speed ergos. You just have to live with a ghost click. And 7 speed cassettes can be fitted on modern 8/9/10 Shimano freewheels with a spacer.

    i have heard that before but forgot about it. That's great! I already have a suitable shimano 7 sp wheelset, so I just need to get a 28t large 7 sp cassette and a new campy medium cage mech and I'm set. Awesome!
    The ghost click doesnt bother me.

    Really, all a medium cage does is take up extra chain slack on a setup where there is a small (granny) front ring. People have reported successfully using Nuovo Record RD's on 28T cogs, so you're 8sp short cage RD might work. You're not running a granny ring on the front, so you're unlikely to need that much slack pickup.

    But if you do decide to go with a medium cage, this guy at Serotta forums has an 8 speed Campy Racing T RD offered in a package deal with some shifters. Maybe you can beg the buyer to sell it to you.

    Right, I know what the longer cage does. I dont own an 8 sp short cage rd, or you can bet i'd be trying that.

    I can confirm this, having running one on a 28T cassette.

    With all this discussion about Miche cassettes, can anyone vouch for the reliability and shifting compatibility of these cassettes over a decent length of time with Campy drivetrains, 8-speed or 9-speed?
