Q: I have 99 Record 9 speed
ergo sifters, 99 Record Rear der. and the c9 Campy chain. I've purchased
a set of Mavic wheels which has the shimano style freehub. My bike shop
tells me I can use the dura-ace cogset with no problem because the
spacing for 9 speed campy and 9 speed shimano is so close. I've tried
this setup and it works but not very smoothly. Can you suggest the best
setup for me? should I use the mavic cogset? Older style shimano cogset
with spacer kit? What do all the pros use when they put Mavic wheels on
thier campy equipped bikes? HELP!!!
C-O: The spacing doesn't work all of the time between the
two. I know that Mavic has their own cogset that will probably work for
both. I would check into trying those.
Q: I have 97 Record 9spd
Ergolevers. The brake lever is badly scratched on one and I want
to replace them both. Can I fit the newer carbon brake levers to
the 97 Ergopower body? If yes, what is needed for the job?
C-O: Sorry to say that the 97 Ergopower body style is
completely different from the newer type. They will not fit.
Q: I am currently trying to
convert my GT Ti rd bike to Campy. The stock Ultegra (can I use that
word here?)is not cutting it. I wish I could just plop down the cash
& buy a new groupo, but I just bought a new Mtn bike & the wife
says NO. I have replaced the 9spd STI levers w/ Veloce & the rear
der. as well. Ive been told by several shops & more than one rep.
that this should work, it doesnt! I cant seem to get it to shift
properly. It shifts from the 12 to the 13 ok, then it skips the next
one, by the time I'm in the 23, there is one more click in the lever (it
doesnt shift into the spokes though). I borrowed a Chorus wheel from a
friend & tried that & it shifted perfectly. I really can't
afford a new hub & cassette right now & everyone says that the
two are completely compatible this year. Can you help? I would
appreciate it, I've already e mailed Campy & the mail was returned,
undeliverable.
C-O: The 9 speed Shimano and Campagnolo are close enough
that is works some times 100%, not always ( as you know ). The
Ergopower do have tighter tolerances so that might have something to do
with it. First thing to check is that the spacing of your cogset is
even. Since the Chorus hub worked it makes me think of that. What chain
are you using. If it's a newer chain and the spacing is off on the cogs
this will magnify the problem also. You can order spacer kits for
cogsets to make Shimano compatible with Campagnolo so that may be an
option for you.
Q: What
tools do I need to overhaul my 9 speed chorus rear hub . Is it easy to
do yourself or its best to leave it to the LBS . Is there an instruction
manual regarding this?
C-O: To overhaul the hub you will need a 2mm allen, 17mm box
wrench and cone wrenches. Loosen the 2mm allen on the drive side
locknut. Remove the drive side locknut with the 17mm wrench. The freehub
body will slide off ( watch the pawls and springs, they might fall out
too ), At this point you have an old type traditional hub. Hold the hub
in an axle vice on the drive side. Use the cone wrenched to remove the
lockouts on the non drive. When this is done the entire axle will slide
out the right side of the hub. Remove the seals on both sides making
sure not to damage them. Be careful not to lose any of the bearings.
Clean everything. When re-assembling use a good lithium based grease (
that's what I like ), the right side ( drive ) takes 10 7/32"
balls and the left ( non-drive ) takes the 9 1/4" ones.
Reinstall the seals. When installing the axle and adjusting it,
everything is done from the left side. Adjust the hub so there is no
play at the axle. Don't get it to tight or you will damage the cones and
cups. Re-install the free hub body. You will need to use something to
hold the pawls down, like a piece of string. When you install the
freehub body it will slide on the axle. Install the split washer then
the flat washer and then the locknut. DO NOT OVER TIGHTEN THE LOCKNUT,
all you need to do is snug this nut. Re-tighten the 2mm allen. That's
it.
Q: I
have a creak in the bottom bracket area of a 1999 Record gruppo. I've
tightened chainring bolts and now I have removed the BB and will
reinstall and tighten. I know I need to use anti-sieze , any suggestions
on product ?
C-O: The first thing I would check would be if the bottom
bracket has been faced and tapped. If not have it done. Second I usually
use Teflon tape on the threads. This is a dry lube and it also locks the
bottom bracket into place. Make sure the bottom bracket cups are torqued
to 51ft lbs. Tighten the crankfixing bolts to 28 ft lbs.
Q: Last
spring I purchased a new bike with a 9 speed Campy Chorus gruppo.
What special tools will I need to routine
maintenance on this bike?
C-O: There are not many special tools required to work on
Campagnolo components. Really the only one id the bottom
bracket/cassette lockring tool. Everything else uses standard tools.
Q: How often should I lube
my Vento hubs?
C-O: You will need to service the hubs from time to time.
The Vento hubs are a regular ball bearing type of hub so they will
require maintenance. It depends on the conditions you are in but most of
the time you can do the overhaul once a year, more if you are in the wet
a lot.
