Three Speed tob tube shifter cables??
Hi all,
Hi Sheldon :=)) I have tried to get n touch with Paul from Cycles of Yesteryear, but haven't managed to touch base so far. My BSA (should that be BitSA?) is comming on, i've got the hubs and the headset moving smoothly, the main items left are the brakes, chain and the gear shift. I would really like to use the existing gearshift which is located on the top tube. I've lost the nice shiny cover which had BSA stamped into it unfortunately (anyone got a spare?? :=)), but the gubbins all seem to be there. The 3 speed hub is a BSA and the little dangle chain thingy coming out of it has a course (ooh err missus!) thread. I do have a little brass thread converter thingie which converts to a fine (metric??) thread which is almost but not exactly unlike the internal thread on the SA (or SA look alike) widget which would then clamp onto the cable - Phew! What I would like is a cable which would go from the top tube shifter down to the dangly chain thingy in as few moves as possible. Still with me?? When I got the bike, it had a cable with an adjuster which fitted the thread converter thingy properly, but didn't have any kind of nipple on the other end. This too has now been lost :=(( There is a plate with a hole in in the shifter for the cable to attach to and this has some solder on it, so I suspect someone tried to solder the end of the cable in there and it failed. Does anyone know..... What kind of nipple or other arrangement would be usual in this shifter?? Where such a cable might be obtainable (UK Pref) today? Thanks for listening. |

I've lost the nice shiny cover which had BSA stamped into it unfortunately (anyone got a spare?? :=)), but the gubbins all seem to be there. That's called a "quadrant" shifter.

What I would like is a cable which would go from the top tube shifter down to the dangly chain thingy in as few moves as possible. This is easier than you might expect. The standard Sturmey-Archer replacement cables currently available work just fine for this application. The fitting at the shifter is the same as used by the handlebar-mounted trigger. You just throw away the housing and cut the cable shorter. These cables come with a bolt-on "anchorage" that has the female threaded fitting to connect to the indicator spindle chain. You can see pictures at: http://harriscyclery.com/sturmey-archer-parts.html If you are in the U.K., it would be silly to order something like this from the U.S. but I would expect any decent bike shop over there to have a Sturmey-Archer cable. If you have trouble, try St John Street Cycles, Bridgewater, Somerset...I'm sure they'll have 'em.

You can see pictures at: http://harriscyclery.com/sturmey-archer-parts.html Thanks for that Sheldon, but I have one of those already and can't see any way to attach it to the gubbins in the Quadrant Shifter. It may be that the BSA ones were different than the SA, or maybe someone has done some serious buggering about with this one. I suppose at a pinch, I really ought to be able to drill a couple of holes in the plate so that the cable goes through but the nipple doesn't. I have been trying to contact Cycles of Yesteryear in to get some bits, I'll try the Co you mentioned too. Perhaps you might consider having a "Where to buy this stuff if you are in England" page on your site with Links to some of the specialist shops over here. (Perhaps they'd do a link exchange). I found your site with no bother (and it's great!), but had real trouble finding suppliers for stuff over here. I am now finding them, but sadly too late for the tyres (bought some from Halfords which are the right size, but the tread pattern is more like what I used to have on the 700cs on my 80's tourer). Cheers Zikki. |
