Grip Shift Compatability

on a *seven* speed hub? Or should I just settlte for the SRT-600? Does
anyone have Grip Shift that really *doesn't* like them?

I've put a 7 speed wheel on a Gripshift-equipped 8 speed bike. If
adjusted perfectly, it will work OK for a little while until the chain
gets a little dirty. The problem is that the spacing for 8sp is .1mm
narrower than for 7sp. Between just two cogs this is not a problem,
but over the whole 8 speeds the error builds up to almost millimeter,
enough to cause hesitant shifts. Typically, you might be able to get
smooth shifts at one end of the cassette but not the other. If you're
going to continue to use 7 speeds, get the shifters that were made for
it. They *are* different. There is nothing wrong with 600 series
Gripshifts, or 500 series either, they are not inferior.

works beautifully. There is an extra click with no change in gear.

The SRT-800 will not be compatible with 7-speed. The SRT-600 will work and is not really
"settling" since the mechanisms are identical.

Here, you get into that shady area between what SHOULD work and what DOES work. Technically,
Shimano 7-speed and 8-speed have different cog spacing. This makes 8-speed shifters incompatible
with 7-speed cassettes and vice versa. However, you can sometimes get it to work anyway. This
is also true with mixing Sachs, SunTour, Campy, Shimano, GripShift, etc. Even though the
manufacturers tell you that many specific combinations are not compatible, many work just fine.
However, many don't.
My rule of thumb is to experiment with what you already own. If you can get a SRT-800 shifter
that you already have lying around to work on your 7-speed cassette, then great. However, I
would not suggest going out to purchase a set of SRT-800 shifters hoping that they will work.
They may not, and then you just wasted a lot of money. Save yourself the potential aggravation
and buy the SRT-600s.

YOu know my buddy just recently got the XRAYs for his 7 speed STX drivetrain.
There's a "ghost shift" at the end but i noticed that the shifting isn't very accurate.
This is due to the spacing between the cogs. I think there's like half a milimeter
difference or something like. It may not sound like much but it will be a large hassle
after awhile. If you're like me, the shifting must be very perfect. I wouldn't bother.
Besides, if there's nothing wrong with yer STI system, why change?? The STI is
more ergonomic and faster.
