No, I understood that you were joking. I just couldn't let it go anyway.

This is classic & vintage? Makes me feel old..
Anyway, this Campagnolo trick is one I've used successfully consistently on many drivetrains, including one I was riding yesterday:
Works perfectly every time. The Campy 10-speed shifters (best ever) pull on average 2.8mm of cable per 'click'. The old Campagnolo derailleurs have an actuation ration of 1.43:1. This is lower than the newer Campy actuation ratio of 1.50:1.
2.8 x 1.43 = 3.95mm, which matches Shimano 10-speed cog spacing. Campagnolo 10-speed cog spacing is 4.15mm - on average.
I know - there are small spacing differences across the Campagnolo cassette, and the shifter cable pull. But this hacks provides perfect shifting on every cog every time.

- 10 speed Ergopower shifters (any)
- Older Campagnolo rear derailleur (1991-2000 vintage)
- Shimano 10-speed cassette (cheaper and more easily accessible).

The 2015 and after have an A on the shifter body. The 2015 derailleurs have that weird criss/cross outer parallelogram shape.

Super info. I have been messing with Campagnolo spacers on Shimano hubs, but then you lose 1 cog/speed. Full potential would be if a Racing T derailleur could be made to clear a 32 or even 34 cog, introducing the Campagnolo mullet drive train!! I suppose that won't happen, anybody tried this?

(You don't need the extra space on the first and last because the stop take care of things.)

Speaking of spacers, here's a trick for you. If you have an 11-speed Shimano hub and a 10-speed Ultegra cassette, you can replace the 10-speed spacers with 9-speed Shimano spacers and it will be very close to 10-speed Campy spacing -- close enough that the indexing works with 10-speed Campy shifters and derailleurs. You need an 11-speed hub because this makes the cassette too wide to fit on a 10-speed Shimano hub. You also need a spacer behind the cassette. I don't remember the size of that one. I experimented until I found one that worked out of a set sold for single-speed conversion.

Yes, and friction 5 through 10 as well. BTW I have a 9s Shimano mech with a SRAM 11-30 10s cassette and a set of Campy C-record era passive friction DT shifters, working very nicely on my Terraferma. TRL brake levers feel a lot like Campy Gen 2 and Gen 3 Ergopowers. But I also have a few pairs of unused (currently unemployed would be more accurate - lol) Ergopowers. It sounds like this new information may mean I can use the Ergopower 10 sp levers with 6700 wheels for a 10 sp system?

Yes. Just pair the 10 speed ergos with an 8-speed or old 9-speed rear derailleur and you should be set

With a minute or two free I went downstairs and looked at my derailleur and levers. I have a Racing Triple 9 speed of apparently the early variety (b screw but no h screw). The levers read "Carbon BB-System"on the body and "Chorus" on the lever. How do I tell what age my levers are?

Thanks. The entire drivetrain came from another bike, so hopefully the person who built it understood the ins and outs of this transitional period.
