non-conventional shifter locations?

in my last project i was again confronted with the decision of where to place the shifter. The placement should suit the riding style so downtube is out of the question.

I'm using a Sturmey Archer SRF-3 hub and proprietary shifter. The Philippe Porteur bars have a diameter of 23,8 and i'm pretty sure there are no clamps for this size. I don't want to splurge on VO / Paul mounts either. In the past I've placed the shifter on the stem shaft which has worked well and would suit the upright riding position of this bike. I would have done it again, only I had wired everything up before thinking about it *doh* and didn't want to take everything apart again.

Anyhow, I got a little funky and modified and old Huret clamp to accept the modern shifter and it shifter on the top tube, just like older Motobecanes used to have.

This got me thinking of other non-conventional locations one could place the shifter... on the bike frame of course SA makes a seatpost mount for 27,2. I wonder how awkward that is to use. I was thinking maybe the seat tube below the top tube could also work.

I'm curious to see what other people have come up with!

I don't have any suggestions for you but am intrigued by your mounting on the top tube. Would you mind posting some up close photos of your shifter & mount on top tube? Thanks.

I've heard tale of a shifter mounted under the saddle...

I also relocated my downtube shifters to the toptube with and origin8 adapter, then used a v-brake noodle as guides, wait... let me snap a photo to illustrate.

That was actually the standard position at one time.

I am thinking of moving the DT shifters on my Motobecane to the top tube when I install a swept back townie bar. Nice to see others doing it.

René Herse used seat tube mounted shifters on his démontable frames, to avoid cable problems when separating the frame:

Another sturmey shifter on the top tube. I don't like the shifter; I think I may see if I can get an old-style trigger shifter to work.

removed some XT trigger shifters back to my Chorus setup on the Bruce Gordon, still routing down the downtube and added the noodles facilitate the cable position, shifters are close to the flats on the trekking bars, haven't taken it out for a long ride yet

Top tube shifters sort of remind me of this.

At one time, top tube location wasn't unconventional, as seen in the placement of quadrant shifters.



I've always been intrigued by the seat tube placement of Herse demontable shifters. Anyone have real world experience using these or something similar?

This was the original position of the shifter on my 1958 Motobecane Randonneur. 4 speed, in all of it's glory!

those SA quadrant shifters are sweet! However, I worry about their reliability indexing on a newer hub. Probably me just being paranoid. I'm thinking of moving the shifter to the seattube , along the lines of Herse. Anything he did is worth copying in my opinion.

I also had this idea originally and bought the trigger shifter. the quality is much lower IMHO.

I see you used the curved mount for the your shifter. what kind of clamp/band did you use?

On my Fothergill I have a hybrid drivetrain. I shift the hub with a conventional SA trigger on the handlebar and shift the derailleur with a homebrew quadrant shifter on the top tube.


The old Sturmey Archer quadrant shifters are fun, and charming in their simplicity, but the ones I've used have been unreliable. I'm not sure whether that's because of the condition (they haven't been made in 75 years, and they tend to show their age) or the design. Probably both. I believe the pull is the same as for a modern hub but even so I can't recommend one. The new shifters are the best I've ever seen (I use one on the bar end).

I also think the quadrant shifters look quaint and charming and vintage-ish hip, and all that. In the back of my mind, though, I always worried just a tiny bit about coming down off the saddle and forgetting that thing was sticking straight up off the top tube.

Yeah, you don't want to spend too much time thinking about that. In practice, I haven't found it to be a problem at all. When you stand over the bike, you stand much farther back; you'd have no reason to stand so far forward.

Raleigh mini-velos have the shifters on the head tube (I believe I've seen this on minis from other manufacturers as well.)
