O Ring Supplier

[mondobongo]

Does anyone know where I can get a replacement O Ring for my Sigma Wireless Speed Sensor? Looked online but smallest order I could find was 17! from a supplier don't want to pay £12 for a new sensor just to get O ring.
Zip ties will not work as a cheap fix.

Mondo, what size do you need? I've got the o rings from my Aldi comp (the dog chewed the actual computer, so they're surplus to requirements). I believe the bikemate computer was a rebadged sigma, so they might fit...

they should do, when i got new forks the lbs used zip ties to secure my sigma sensor.

the bikemate stuff does seem compatible with sigma, but i don't know if the o rings are the same. worth a try though.

You mean the bit that holds it to the leg of the fork mondo? A plumber's merchant or diy place should have something near enough...

You could also try a motorspares shop. Take the original if you can

Could you not use an elastic band?

Check out your local Yellow Pages for bearing suppliers or engineering supplies. My local man is happy to supply one off O-rings and bearings for that matter.

This is probably the best answer.

I've found packs of 50 (up to £5),
sizeable kits of assorted sizes (£10),
or DIY splicing kits with lengths of cord and some glue
(£24)

Mondo, if you're not sorted already, PM me, I've not measure the O rings I have, but they're nears as dammit the right size by the looks of things.

Monzo,

If you give me the cross-sectional diameter, I'll probably be able to make you one. Won't be for a few weeks though as I'm not at work for a while.

PM me if you're interested.

Ta,
AM.
