grip shifters on end of drop bars.

Hey so I have these drop bar ends which I have attached grip shifters onto like a bar end shifter.

Anyway what iv noticed about the drop ends is that when coming up from the drops It is a bit uncomfortable.

Would mtb grip shifters fit on the end of a normal drop bar or is the diamater still a bit too wide.

Currently in using a specialised sirrus "road" bike.

I have tekro v brake drop levers and have thrown my grip shifters on the end of origin8 drop ends.

I have sawn the bar down to the correct size but still think I prefer the traditional curve as apposed to the ergonomic.

Grip shifters are designed to fit on bars that are 22.2mm OD; most drop bars are 25.4mm or 26mm OD - thus they will not fit.

The easiest solution is bar end shifters, which are available in both friction and index. For example:
https://www.amazon.com/MicroShift-Do...ifters+9+speed

There are solutions keeping the grip shifters, but they are heavier, more complicated and require custom fabrication.

The marginal "GMC" 'Denali' used a grip shifter pair right near the stem... bars come apart in the Center, I Guess,

High end there are some from German Bike Builders that let a R'off grip shifter sit on the bar near the stem. similar, a drop bar that is split and 7/8 to fit the shifter.


HubBub designed an extension to go in the end of drop bars. like a bar end shifter , same expanding clamp hardware.. added on tube is 7/8"

Another option from UK SJS Cycles is a T mount like a threadless stem, the T is 7/8" tubing. it takes 27mm of steerer spacers. under your stem.

& Consider Gevenalle - retroshift.. Brake levers , with a front mounted shift lever, Indexed or Friction ; V or Cantilever Brake Models.

22.2 is the lever, grip area dimension of flat bars, 25.4 or 26mm is the diameter of the clamp area. Most road bars have a diameter of 23.8mm (15/16") outside the clamping area.

Some of the really old, cheap, (and super heavy) steel drop bars are smaller in diameter and could possibly fit a set of grip shifters.

Really though, pretty much any other shifting setup will probably be better. I think I'd prefer friction stem shifters over grip shifters on the end of a drop bar.

Bar-end shifters are the obvious solution. Downtube shifters can work, but it depends on your frame.

At one time when Grip Shift was first starting out it was focused on the Tri market and only made drop bar end located twist shifters. IIRC the cable path was friendly with drop bars.


But current twist shifters are designed around flat bars so the 22.2 clamping fit, not the 23.XXX of most drop bars without any mods or adaptors.


Has the OP looked at/considered common bar end levers? Andy

See sample of early Grip Shift below. They did work but gearing selection back then was pretty much Shimano or SunTour 6- or 7-speed and you had to buy the right GS setup depending on which you had, with double front or triple front, so maybe not compatible with what's on your bike now. Lots of GS SKUs to cover all the options.

+1. Barend shifters would be the way to go.
