Yup. I don’t really know what, if anything, I did. While riding yesterday, I had to slow down quickly and also may have bumped a curb lightly at the time. Later I noticed that the uni wouldn’t downshift, so I hopped off and tried it by hand. But then today, I tested it and was unable to downshift under any conditions, either riding or otherwise.
Help! I don’t want to have to send it back. This is a 2nd gen hub, and I want to use it at NAUCC. Thanks.
It might be that the shift lever has got messed up a bit. It’s maybe worth taking off the shift buttons and looking at what’s going on under there. If it doesn’t look like there’s anything bent, maybe taking off and putting back on the shift buttons might fix it, if they’ve just got a little bit bashed?
I’ve never done it, but I think you need to use the two little tools that came with it to take off the buttons, I think you hold the button still with the flat thing, and unscrew the tiny allen key in the middle.
You’re exactly right. In fact, I told Florian that I wouldn’t send it back till after NAUCC – unless it fails me completely before then. I’ll be riding to work today; round-trip it’s 9 miles. If it holds up for now, I’ll just have to get used to riding in high gear.
I have a feeling that I can repair it with some button-jiggering. I don’t think that I’ve damaged the shift buttons, but perhaps one of them got wonky anyway.
To clarify, the buttons can move in on both sides as they normally do when we shift, but when I put it into low gear, nothing happens.
The recumbent bike shop here in State COllege has schlumf geared hubs on some of their cycles, Florian even stopped by the shop once, I gather from talking to the store owner. Is there a recumbent specialty shop in NYC that would have such things and the technical know how to help you?
There must be some local recumbent bike specialists. Thanks for the suggestion. I’ll look into it. There are now three local gunis, so it might be good to have someone around here who can service our special hubs.
I took it out to try it today, and it didn’t work – at first. Then I just pushed the wheel around and spun it around and lo and behold, it works. But it didn’t work the next time. But then on my way to work today, I tried to downshift and was happy to discover that it worked.
When it fails, what happens is that the button goes in but the hub stays in high gear. My hunch is that I can ride it in high gear safely as long as the hub is set to high gear.
