I have a 2002 Record 10 group with 53/39 and a 12-25 cassette. The current
chain is a Wipperman stainless with about 1000 miles. The cassettes
have less than 1000 miles on them. The chain measures within
tolerance. If and only if when I stand on the pedals I get a noise
from the three lowest (21-23-25) gears. It matters not which
chainring I'm in. I swap out the wheelsets and the noise remains.
This noise appeared suddenly about three weeks ago. There is no rub on the front der.
I have already greased the freehub and tightened the locknut securely
and after the wheel swap today I am unsure where to go from here. The
frame is a Serotta Legend Ti (titanium).
Thanks in advance.
