Mixing cogs from Campy Cassettes

[Kendall]

While I have numerous cogs from a few different Campy cassettes, I have not
been able to mix and match to get different combos with any success. The
hybrid cassettes I've tried for my 20" wheel travel bike friday shift like
****. I know there is a Campy system and cog ramping etc. and I see the
reference markings etc on the cogs but it looks like Campy has made it
impossible to put something other than what they offer together for a custom
cassette. Any tricks or secrets?

TIA,

Kendall

With my limited experience, it's best to keep the smaller cogs with
the ramps lined up properly. Then it takes some trial and error. I
wanted to make a 12/26 x 10 sp. I had a 12/25 and thought that I just
needed to take the 23-26 off a 13/26. It turned out what worked best
was taking the 19-21 and 23-26 off the 13/26.

The mixing works better if you use a Shimano HG x 9sp chain.

I customize my Veloce 9-speed cassettes with two or three Marchisio* cogs
at the large end. Shifting is not as good as with standard cassettes but
I wouldn't call it "****". I'm grateful to have exactly the gears I want.

What ratios are you trying to achieve?

I took the 28 from a nine speed 13-28, and put it on a 13-26, in place
of the 26. Worked a treat. It gave me a reasonable range of gears for
the day, with a bail-out gear for getting up Mt Buffalo at the end of
the day. I didn't have any significant problems with shifting.

Regards,

Suzy

It works fine with 9sp cassettes. On 10 sp cassettes, the largest cog
has to sit down a bit over the freehub. A 29 would have to come off a
Veloce 29.
