WWYD -- Shifters

What Would You Do?

My fiancee has this old Centurion Sports bike that she's having more darn fun riding. It's been
modified to be more comfortable for her, a small woman with narrow shoulders and short arms. Kind of
like a little T Rex in that regard.

With flat bars and short-reach levers, riding and braking are working for her. But the old downtube
friction shifing is awkward and clunky. There's not a lot of room on the bars for any shifters I
can think of.

But I bet the folks on this forum will have some Mite-E-Fine ideas about how to make some
improvements.

Please see http://www.jmscrapbook.com/2003/CenturionBB.html

for a photo and a description of the various relevant bits on the bike.

Thanks!

You could do shimano RF+ or gripshift. RF+ pods would require no modification to the current setup
and would work with the current drivetrain. Gripshift would require cutting the grips a bit to fit.
Not that difficult to do and should not be too pricy either.

Watch those comments or she'll be your x-fiancee.

Why not use Shimano Rapid-Fire shifters/levers? That's what I put on my wife's road bike when she
insisted on upright bars. The rear will shift perfectly as long as you match the number of gears.
The front will not be perfect, but you can set the center position first, then use the limit stops
on the derailleur to adjust the other two. The mountain-bike front shifters pull more per click than
road ones, but it works OK this way for her. With her weird front shifter maybe the situation will
be even better.

I'd go thumbshifters. Shouldn't be too hard finding some NOS XT or Suntour
XC-Pro thumbies. Will the RF or Gripshift index properly with that 5 spd?

I didn't notice the bit about the 5-speed. But if she has 130mm rear spacing, you can put in a
cassette road hub, and give her 9-speed in the bargain for not very much money, if you can re-build
her wheel.

That might be enough to make up for the t-rex crack.

Can anyone suggest a source for XT or Suntour XC-Pro thumbshifters? I thought Harris Cyclery might
have them, but struck out.

May be. I got mine for $40 at a swap meet.

Close enough. Road rear standard now is 130. That will work fine.

Personally I don't like twist grips. Rapid Fire are much better.

The price is not too high. That then brings me to converting her

These days, I would go to 9. Price difference is minimal.

Unless she reads this newsgroup.
