Total cable pull of Suntour Command shifters???

Folks,

Could anyone report here with the numbers for both left-hand and right-hand shifters?

Thanks,
IK

Have you actually acquired some? As far as I know, they pull whatever the relevant 6s or 7s Suntour downtube and bar end shifters of the same era did. If I recall correctly, not all positions were the same distance apart (uneven spacing on the freewheel), and Suntour shifters will only index perfectly with Suntour freewheels or cassettes. This might be false, though.

Either way, the pull will be weird.

Check these out, though, for a similar idea:

Kelly Take-Offs are another option.

I've likewise long wished somebody would produce Command Shifter-type things for modern Shimano-spaced indexing; they seem like such a great idea.

dave35,
I plan to acquire those if the total cable pull of either the LH or RH is at least 52 mm.
You seem to be providing solutions for a problem I do not have.
I am not interested in shifters in general, not in index shifting whatsoever. My question was very specific:

All I need is the total cable pull capability of the Suntour Command shifters, LH and RH.

I think we have some at work, I'll try to get you an answer next time I'm down there (probably Monday).

Hence, the question.

To clarify:
I am not asking about what is the span of RD movement or how many cogs could the RD get aligned with.
I am asking about the actual amount of cable pulled by the shifter when the wing ("thumb") lever is moved entirely throughout its full range - detent to detent.

Given the company died, went out of business, back in the 20th century, good luck.

Most of the parts we use for our vintage bikes are from dead companys.

Are you sure about the 52mm most RD's require about half that much cable pull the majority of Suntours stuff had a max cable pull of a little more the 30mm.

I have a set...if someone can tell me how to measure this, I'll do what I can.

Mine work decently with 7sp Shimano HG casette and rear d.

Aaron to measure the pull you'd put the shifter in one extreme position, make a mark with a sharpie on the wire...lets say for arguments sake at the point where the wire exits the RD housing loop, then move the shifter to the other extreme and make a mark where the wire is exiting the RD housing loop. Then measure the distance between the two.

@ the OP, if you remove the indexing on the RD shifter you can pull a freakin buttload of cable with these shifters. I can get damn near 360 degrees of rotation out of mine, not that you'd ever do that...but you could.

The absolute lock-to-lock cable travel for the 7sp models I have here: 58mm for the front, 53mm for the rear.

Note that the rear has significant indexing clicks even in "friction" mode.

Sorry for misreading your post. (I don't like it when people misread my posts, either.) I thought you meant the pull between indexing clicks.

It's possible to disable that, there was a thread in C&V not too long ago. Actually, I think it was Zaphod who started it.

I actually have a single rear command shifter, converted to friction, waiting for an appropriate bike to use it on.

mechBgon,
You are my hero!
Thanks man!

Now I need to buy a set. Any sellers?
I see them every now and then on ebay for a lot of dough....

To the other posters:
I never intended to shift RD with these. Need them for something else - and before y'all start screaming how "you can not do that", let me assure you - yes, I can. I happen to be quite handy, especially in bike-related affairs, having tinkered with bikes since the mid-60s.
I intend to modify 1 of these shifters, change (or add) its indexing, and control a 11-speed Alfine IGH. The original Alfine 11 shifter sucks, as it is bulky and located on the straight portion of my bullhorns, while my brake levers are on the horns, and that's where my shifter belongs as well. The ergonomics of the Command shifter is superb for my purposes.

I know that Versa makes 11-speed brifter, both pricy and inadequate for bullhorns. Jtek have not yet developed the 11-speed barend shifter - and since I'm not getting any younger, I can't wait forever for the market to offer a solution. I'd rather hack my own one.

Cheers!

its pretty easy once you get the little circlip off. Just yank out the tiny ball bearings, add a thin plastic washer, put it all back together and bob's yer uncle.

best of luck to the OP. love to see some pics of it once you've got it set up. Definitely interested to hear how the Alfine works out w/friction shifting.

Ditto -- looking forward to photos and the "how to".

The Versa drop bar shifter for Shimano Alfine 8 is pretty dang bad, and I'm wondering what to do when it finally bites the dust.
