Can someone explain to me why there are no 'old school'
thumb shifters available for a 9-speed cassette? I am
moving from my '89 Giant Iguana with it's Suntour thumbs
shifters (switched to friction) to a new road/hybrid bike
where I will have a straight bar. When I was on a tour last
weekend, I started to notice how everyone was clicking
through their gears while I was quietly and smoothly
shifting with my thumbs.
I really like my Suntour thumb shifters particularly
because:
a) They are smooth
b) They are quiet
c) They allow me to trim my front derailluer to adjust for
the crossover on my low inside rear to big outside front
and vice versa.
How do the new "raid fire" shifters adjust for crossover? It
sounded like there was a fair amount of grinding on the tour
as they downshifted and I wasn't sure if there was any way
to trim the front derailleur on the fly. Is there?
I have searched far and wide on the internet only to find
that you can get a few old Suntour 7-8 speed shifters (right
handed), but there doesn't seem to be any really good, new
solution for a 9-speed rear casette and a 3-speed front
chainring.
I did see the Shimano Tourney components which includes what
appears to be an old-school type shifter, but it's only
intended for 5, 6 and 7-speed drivetrains and isn't intended
for heavy duty use (it's for kids bikes).
The Deore LX has been recommended, but doesn't it click like
the rest of them?
I have seen a few random Sunrace MTB shifters on
bikeman.com, but I'm not so sure they would work with a 8 or
9-speed cassette (which is what I want). I saw a Suntour XC
Expert Thumbshifter for the right hand, but what would I use
for the left?
Does anyone have any suggestions (short of starting my own
business and manufacturing my own)? Is this a freakishly odd
thing I am looking for, or has the industry just left this
very simple item behind in favor of more complicated and
expensive shifters?
Thanks,
Warren
