Hi

I've just bought one of these from Wiggle, and I didn't notice it is
for 9 speed. I have an 8 speed sprocket - is there any reason this
wouldn't work for an 8 speed? It does say specifically 9 speed on the
box.

I don't want to fit it until I'm sure incase I have to return it...

Can you recommend alternatives if I have to exchange?

Many thanks

I think it will work without problems, I used long time a XTR front
derailleur labeled with "Mega 9" on a
8-speed drivetrain without problems on my MTB and on my touringbike a
Campagnolo Veloce front derailleur
also a 9-speed without problems with a 8-speed drivetrain, the SRAM
x-gen looks very good with the sturdy body,
so what use it ;-)

thanks for the reply

Do you know what the physical difference between a front mech for 8 / 9
speeds is - I don't want to fit it, try it and scuff it and find it's
not right!

do you think it's a marketing thing, i.e. they're trying to get
everyone to buy 9 speed?

Any front mech will work with four speed, or five speed, or six speed, or
seven speed, or eight speed rear ends. It doesn't bother the front mech
one whit what you have on the back. My winter bike has a 2005 ten speed
Campagnolo Record front mech and a 1992 Sachs Huret six-speed rear mech.
It works fine.

I use now on both bikes 9-speed drivetrain, when I compare a "real" 8
and 9-speed FD there no difference
between thedistance of inner and outer plate, but there's a difference
at the chains a 8 is 7.2mm and a 9 is 6.5mm that's
only 0.7mm difference and the jump from 8 to 9.speed is a normal
evolution and of course marketing, I could not find
a "big" difference in lifetime of sprockets and chain if there similar
quality

Is there no difference in the cage width to account for the difference
in chain width between, say, 10-speed and 7-speed chains?

....so I guess even if there is a difference in cage width, it doesn't
matter one bit!

Do you have to trim the chain more frequently? I thought that Campag made the
front mech cage narrower as chains got narrower?

Mind I know Shimano front mechs got wider when STI came in - not sure if
Campag ones did.

There isn't any physical difference and never was. Ten speed ones /may/
be a bit narrower across the cage, but as I say I use a 'ten speed'
front mech with a six speed rear, and it works extremely well.

Nobody's making quality 8 speed anything any more, and I suspect that
SRAM think anyone still using 8 speed will get an X.4.

There probably is, in fact, but, as you say, it doesn't matter.
