shimano sora flightdeck

[Jon_H]

I was just wondering is it possible to retro-fit a shimano sora 7 speed
flightdeck levers to a 6 speed rear hub. the front shifter should work as it
is built for a double but will the rear work ok.

cheers

There's a good chance that it would work using the "alternate cable
routing" shown at: http://sheldonbrown.com/dura-ace.html#indexing

However, it would make more sense to just convert to 7-speed. The
expensive part of this conversion is the shifters, and you're already
going for those.

Assuming you've got an old-style thread-on freewheel rear hub, you can
easily replace the 6-speed freewheel with a 7 speed unit for $20 or so.

You will also need a new chain, but odds are you already need a new chain.

thanks for the advice but i am waiting for the bike to arrive still so can't
comment on the freewheel but more than likely a screw on, incidentally I
have a six speed freehub on my old falcon would this be as simple to convert
to 7 speed changing onlt the hub and chain.

Just think, someday you'll have a customer who doesn't understand the need
for all those cogs, and you'll be able to look at him as if he just doesn't
get it and say "But this one goes to 11!"
