Archer Components Electronic Shifting Conversion
« on: January 26, 2021, 03:18:00 pm »
I stumbled across this gadget recently and it struck me that eliminating the long cable runs on a tandem would be an ideal application for this piece of kit.

https://archercomponents.com/products/d1x-trail

Although it is advertised as suitable primarily for  x 1 drivetrains, I queried this with the manufacturer and they confirmed there would be no issue using it with a 'conventional' 3 x 9 setup.  The only thing I think it is missing is a gear position indicator.  On a solo bike, it's easy to just glance down to check the current gear, but this is not quite so simple on a tandem.

It is not a cheap upgrade, but nonetheless I'm tempted to have a go with this on my Orbit tandem.   Do any other forum members have any experience of using this gadget?

The reviews I've read on the internet seem to be quite favourable, but 'real world' feedback is always helpful.

What does the panel think?

 I'm not sure that I understand how the thing works. Does it pull a specified length of steel cable when you push on a button? Can you actually specify what the correct length is, for dealing with various kinds of derailleurs?

definitely needs to improves on this point if you want to ride PBP or LEL with this device, unless of course if you are very fast!

Also a thread over there. https://yacf.co.uk/forum/index.php?topic=118199.0

Seems it can be configured for whatever number of gears and shift distance you like. And tweak the position for each gear. So should work with just about any sort of gears (except Rohloff).

You can buy a spare set of batteries. Or it can recharged from USB, so you could plug in a powerbank, or maybe dynamo for longer rides.

Looks like you fine tune each shift individually during set-up via the app. So you could use a 10 speed mech and set it to cope with an 11 speed cassette.

Another use for it could be if you had a frame with no derailleur cable stop.

You can buy a spare set of batteries.

The battery door is secured by a self-tapping screw with a 1.5mm hex. Ain't touching that outdoors.

Are the long cable runs on a tandem really a problem? We have a 3x10 Tiagra gear set up and it works well. I was getting some shifting problems as the cold weather and gritting came on (we commute on it in all weathers) but since cleaning and lightly greasing the final cable run to the rear mech shifting has remained precise.

You answered your own question! Long cables are not a problem, as long as everything is kept spotlessly clean and properly lubricated, but real life sometimes has a different say, especially during multi-days rides  :)

My experience with our tandem but also with solos over more than 40 years of maintaining the family fleet and running a bike repair business is that the most vulnerable part of the rear derailleur system is the last run of cable to the rear mech. The Archer system doesn't eliminate this.  :-[
Of course there are other things that can go wrong, especially if cables are allowed to deteriorate and fray, but that should be dealt with easily enough by replacing the cable (I always carry a spare cables on the tandem although I've never needed to change one on the road). However I' sure the Archer system will present its own set of potential problems but how fixable they might be at the road side is another matter.  :)

I agree with a lot of the points made above and would accept that the Archer system is in some ways a solution looking for a problem.  A well maintained conventional system (and mine is) works well.

That said, I do like gadgets and could yet be tempted - we'll see!   :thumbsup:

Looks like the sort of interesting gadget for the curious that would have got my attention ten years ago.  Wonder if they might consider a Rohloff version ...

Bosch make an electronic shift for Rohloff, but won't sell it as an OEM product, only using it on their own ebikes.

I have a Rohloff on my Moulton tandem conversion, using the external shift so it is readily attached/detached when splitting the bike for transport. An electronic shift would be particularly good for the solo configuration, as I  have to put a loop in the cables at the back to take up the excess length, and the friction then becomes significant. There was an Australian e-shift made a few years ago, but it looked rather crudely made and disappeared from the market.

I suggested to ARCC (makers of our e-assist system) that they consider making one, and I know they had a Bosch system in the workshop.

Hmmm.  I know a man who might just be interested in such a quirky project.  He certainly has all of the necessary skills. 

Might have to chat about it with him.
