Old Bike

When you undertake to investigate a bicycle for the first time, take an old one as a subject, and endeavor to put it in perfect running order.

Updates to the Huffeigh

Or, the trouble with buying leather saddles of largely unknown age and condition on eBay.

Be fairly warned. Towards the end of Sunday's Down Townies ride, my used Brooks B72 broke; tore apart right at the nose rivets. It wasn't dramatic or painful, and I knew exactly what happened right away. At least I was able to put a few dozen miles on it before it broke. And, fortunately enough, I had hinted strongly to my wife of my desire for a new Brooks B66 as a graduation present, and it happened to be ready on the afternoon this one broke. While picking up my new saddle at the shop, I also finally picked up a kickstand.

It's feeling good to get the Huffeigh outfitted as a daily rider. I had hoped, while I was investing many hours of work on it, that this bike would be a good ride, and I haven't been disappointed. Now that it's shaping up to be my main ride, I'm getting exciting about doing all of the finishing touches. I've also put on a salvaged rear rack and basket, figured out how to attach the chainguard without it rubbing, and together with the new saddle and kickstand, it becomes that much more useful and complete as a mode of transportation. Next, I'd really like to find a new retro-ish-looking headlamp and dynamo, and also get a pump for the frame.

How To Dismantle a Sturmey-Archer Grip Shifter

Labels: , , , , 0 comments
After another evening of work on Mauricio's 1969 Huffy/Raleigh Sportsman, I took the grip shifter home to try to figure it out. Turns out, it's pretty simple on the inside, but since I couldn't find any how-to guides on the interwebs about it, I thought I'd post one.

The whole works is basically held together by a little spring clip that fits just under the lip of the dial portion of the grip. I used a small screwdriver to pry the clip out of its channel. In the photo below, you see the clip after removal.

With that done, the housing for the shifter (at left above) just comes off (assuming you've already removed the screw that tightens the shifter to the handlebar), exposing the minimal inner workings of the mechanism. There are basically three parts: a small spring, a bearing, and the rotating mechanism to which the cable is attached.  The spring sits in a little hole, and the bearing on top of the spring. When the grip is turned, the bearing slides into one of three holes in the rotating mechanism, either tightening or loosening the shifter cable, and thus shifting the hub.

In the photo above, you can see the rotating mechanism at right with the red indicator arrow on it. Below, you can see the spring in its hole, with the bearing resting on top. 

That's about it. I haven't put the thing back together yet, but I'm guessing that making sure the cable and bearing stay in place while the spring clip is reattached is going to require at least one more hand than I currently have. I'll have to look into getting another one.

There's a fuzzy diagram here of the whole works, and if you combine it with the photos above, you can get a pretty good idea of how it all works. Apparently, though, this was not a very successful design and seems to have only been on 1960s bikes.
