Gripshift on a roadbike?

I built a Rohlof geared road bike where the shifters were
mounted on short mini aero bars, in this case, the profile
Jammer. The I.D. of all rotary shifters is .875" while road
bars are 1/16" larger or .937",so most bar end installations
involve a stub of .875 glued and riveted into road bars. Tom

Has anyone managed to fit Gripshifts to a road bike in a sensible way?

I guess the easiest place to put them would be on the ends of the bars
(drops), but I think it would be a lot safer and easier to change gears if
they were on the top of the bars, close to where the stem grips the bars.
Of course, then you need to figure out a way to get the gripshifts there,
considering the bend in the bars. Does anyone sell drop bars that can be
dismantled and put back together again so that it would be possible to put
Gripshifts on them? Any other ideas?

Another problem I can think of: where to route the brake cables. I guess
they'll have to leave the bars before they reach the gripshift, but I

worry

that they might get in the way when you're holding on the tops of the bars
(e.g. climbing).

Lastly, can someone who has used recent Gripshifts (like SRAM Attack
Halfpipe) tell me if the front derailleur shifter (left) can "trim" the
position of the front derailleur when you've clicked into a position? I
think this might be necessary on a road setup, to allow you to "cross

chain"

without rubbing on the front derailleur (assuming you do this).

Oh yes: why would I want to do this? I think that Gripshifts are a lot
simpler, cheaper and more durable then STi's. I also wouldn't be

surprised

Quoted message said:

if the Gripshift, normal brake lever combination would be pretty light

compared to STi's. There's also the advantage of the Gripshifts being
protected in a crash, assuming they're mounted near the stem.

Thanks for any information and ideas.

Bike Friday sells a variety of split handlebars and will
also split and shim your favorite handlebars for a
moderate fee.

I have a pair of the original gripshifts. Most people don't
remember that their first model was for road bikes (pre sti
days). They fit on the bar ends and the cable snakes up
under the tape to the stem and then dive down to the
downtube shifter bosses. They worked fine for what they
were. I find sti much more preferable. If your interested
in them let me know. They're seven speed. Haven't used them
for a while.

roadbars are 24mm, while the ends of mtb bars are 22.2mm You
would have to modify the ID of the gripshift considerably to
be able to fit them over a roadbar, or you have to resort to
a bar with a stepped middlesection. But you don't want the
splice to fail !

Do you know if the TTT "split-able" bars that they sell are
normally split-able, or have Bike Friday modified them to be
split-able. I'm wondering if I can order the same model of
bars from other web sites, or won't these be split-able?

Thanks,

Travers

Or you could find a pair of the original Grip Shifts which
were for raod bikes and mounted on the end of the bar like a
bar end shift lever. Phil Brown

I have GS on one road bike, but it also has flat bars (MTB
diameter). Check Sheldon Brown's site, he did, at one time,
describe splitting the non-rotating part so they could be
slid over the bend. Have you considered bar-ends?

It's not a Gripshift, but Paul makes a road version of
Thumbies (for use with bar end shifters) that will fit road
bars up by the stem. Bar end shifters, whether mounted at
the end of the bar or on some Thumbies, work really well.
The front one is not indexed as well.

Brown has some NOS drop bar grip shifts on his site-

sheldonbrown.comshifters.htmlOpen ↗

He also, if I remember properly, has a description of
cutting off an MTB bar end and mounting it on a quill stem,
then mounting a grip shifter on this.

try this knight-knight-Open ↗
toolworks.com/web_temp_pics/bike5.jpg it works really well
and the parts are cheap and reliable.

I think they are all modified by Bike Friday. Other sites
won't have them.

Me too.

We recently bought some new-in-package vintage road CX model
GripShifts. Various formats.
