Quoted message said:I have one of the first generation Stumpjumpers. I am trying to bring
it up to date. I've been away from biking for years and am trying to
get back into it, so I have some questions about equipment.
1. The original thumb shifters are toast, so I'd like to go to the
newer click shifters. Will these work with the original derailleurs,
or do I have to upgrade those as well?
2. Can I mount V-brakes in place of the original straddle cable
brakes? The bike now has a bull-moose integrated stem and bars; I'd
like to upgrade this as well, so do I need some additional hardware
(cable hangers, etc.) when I do this?
3. Is there sufficient dropout spacing to go to a 7-speed rear
cluster, or do I just ignore the number 7 position?
4. I have a Schwinn (my wife's, she can no longer ride) with SRAM bar
end shifters. Could I just swap these (and the derailleurs) straight
over?
If this isn't the right group for these questions, could someone point
me to the correct one?
Much thanks for any help!
Bob
Just another nice basic flake.

International Pipe-raising Day, Feb. 20th
Hi Bob,
Welcome back. An old stumpjumper should be a decent ride for what you
want to do. I'm no expert, but I ride and tinker a bit so I'll offer
a little input, and a recommendation.
1) By "click" shifters do you mean indexed shifting? If so, is that
implying that you had thumb shifters that were friction? I've never
seen or heard of such a thing, not to say it doesn't exist. Anyway,
assuming the derailers are indexed, newer indexed thumb shifters
should work just fine. If you meant grip shift, the answer stays the
same, but I should mention that thumb shifters are still extremely
common and from what I see more popular than grip shifters. That
said, I love my grip shift.
2) I assume by "straddle cable" you mean cantilever. If I'm correct,
you'll need new levers or some sort of gizmo intended to alter the
cable pull to make canti levers work with V brakes. I'd just get a
cheap set of V brake levers. You may run into other issues as well,
I'm not sure.
3) Assuming the bike is a 6 speed now, a 7 speed freewheel should fit
though you may need a washer. See http://sheldonbrown.com/harris/freewheels.html
4) Bar-end, as in road bike? I'll let someone else handle this one, I
don't know.
5) While this group is just fine, rec.bicycles.tech would likely be a
better bet. There is way more traffic, it's based on stuff like this,
and you'll likely get all the info you need and more in the fraction
of the time it'll take to get anywhere here.
So, what's international pipe raising day?
