Bike minutiae:

Bike minutiae:

* The back light sometimes goes off when cycling. I infer the batteries jar momentarily loose when going over a bump, and the "on" state is lost. They feel a bit loose. Is there an obvious fix? I tried taping the batteries in place and it made no difference.

(I sort of want some electrically conducting putty to go between the battery and the contact :))

* Last month, the front gear cable snapped off from the handlebars. The bike man from university cycles fixed everything (thank you!). This week, the rear gear cable snapped. I'll take it back and get it fixed too, but any suggestions as to why?

Is anything likely to cause both to fail? Did something snag the chain? I might have changed gear up from the highest gear on one of them, but I don't think I did on both of them. Did someone sabotage my bike, but sabotage the gears instead of the breaks? Do the cables just last a very specific number of months??

What sort of tape did you use? Regular tape isn't always very good at holding heavy things in place very accurately. Try blu-tack?

Good question, thanks.

stuff paper in the batteries?

my gear cable last year broke a year to the day that I'd replaced it (though it had been going for a couple of years before the previous one broke). it then took me most of a year to get the gears working again, due to being excessively lazy.

Hm, maybe it's a seasonal issue...? :)

Scrunched-up tin foil can approximate to electrically conducting putty, I think.

Hm, I'd be scared the crinkliness would make a bad connection, but I can certainly try, thanks.

Carefully-folded tin foil was what I always used to use, during my student days when I got through many bike lights. I'm not sure what I was doing different then, unless it was that I was using lights that took C-size batteries, and thus I used to use rechargeables, which I think might change size slightly as you continue to use them?

Anyway, I tried little bits of paper/card behind the contact (as in, between the inside of the battery's plastic case and the little metal contact that the battery has to touch - in order to push the contact further away from the case), and had some success therewith, but folded tin foil is what I preferred.

Oh, thank you. Then that sounds very convincing, I must certainly try this.
