I have a 10-spd Record crankset and BB that I'm planning to put on a new bike (Rivendell

was told by a local bike mechanic that it wouldn't work, and that I'd need a narrower chain, and
10-speed specific front and rear derraileurs, or else (and then he went on to mention chain
slippage, etc.). Anyone have any thoughts on this? I'm only going to use downtube friction
shifters - not indexed.

You should be fine. Use a chain that matches your cogs, that is, if you're using 10-speed cogs,
get a 10 speed chain; 9 speed cogs, 9 chain, etc. Mixing and matching with dt friction shifters
shouldn't be a problem. For years, before I decided to "upgrade" to Campy Ergo levers/Campy rear
der, I used a mix of simplex retro friction dt shifters, old Campy C-Record ft & rear der
(pre-index; originally designed for 6/7 speed), shimano 9 cassette/hub, Campy Record 9 crank/old
Edco competition bb and shimano 9 chain. Shifting was smooth, fast with no problems. Can't see
why 10 wouldn't work too. For more on mixin' and matchin', see Sheldon Brown's "shimagnolo"

Chain slippage my Aunt Matilda's mustache...the rings are the same width for 10s as for 8s...

Slap it on...We have used friction rears with 10s cranks many times...works fine.

Any 8 or 9sp chain will work fine. I'm interested in the reason that the mechanic gives for the
necessity of a 10 sp chain. The only thing I can think of is that the 10 sp chain costs more and the
profit is more.

Why? Even a cheap off-brand modern derailleur will far outperform anything made by Huret.

It's my understanding that with a 10-speed *cassette*, you need a 10-speed chain, but that's the
only place I've seen where the 10-speed chain is mandatory. (Somebody else here will probably know
of others.) It's quite likely that the tech in question simply doesn't have a good understanding of
the situation. Perhaps all he has read is the manufacturer's literature, and perhaps he's never
tried any crossbreeding. (Or, as some others posit, he may just be greedy; I'm not sure which is
worse.) (And, of course, he may be one of the people who seem unable to grasp the concept that it
might be possible to do something that's not in the instructions.) Chain rings that are designed for
a 10 speed system have been made for compatibility with the narrower chain...but a 9/8/7 chain will
still fit. (The difference, if the specs I've seen are correct, is 1/128th of an inch.) For what
you're doing, a 9/8/7 chain will work just fine, and I can't see why the friction shifters shouldn't
do the job as long as the cable pull length is adequate.

What about the other way around? I'd heard that a 10s rear setup had to have a 10s chain, but that
not all front cogs will work with the narrower links. I haven't had the opportunity to try it
myself, but presumably you've either done it or discovered why it won't go...

[Question is you want to use an older derailleur with new Campy 10s?

I do not see a problem. As long as the derailleur has an adjsting barrel and can swing all 10 gears. Chain is not an issue. Issue may be the pull of the derailleur but I have mixed many parts all my life with no problems. I never ride a full Campy bike.

One of my bikes has Campy 9s with Mavic Mektronik derailleur and Truvativ cranks with a new IRD 10s chain. It works all perfect.

I read your question wrong.

It seems a shop told you cannot use a new crankset on your bike? Total nonsense. Some people should never own a shop or even work on one. Sounds like the bigger shops in the USA. Total salesmen.

Of course you can use Campy 10s crankets. Only catch is you need anew Campy BB that is shorter in lenght then your current BB. That is all.

Your classic front changer will be just fine with a current Record crank

The reverse is a problem - classic cranks have insufficient space between the ring and arm for a big
fat modern front deraileur cage.

There is no reason you can't use a modern chain with your classic front changer but you can also use
a vintage chain if you have one - the rings work with either. You may experience more drag against
the outer ring when in your 39-12 with a fatter chain. I would imagine a wider chain would be used
with a not-ten rear format. Fewer rear cogs keep the chain angle down.

If the hub body length is the same on Campy 9/10 and Shimano 8/9/10, then the chain angle doesn't
always change as the gears increase.
