One more time (sorry). Ksyrium computer magnet suggestions?bill

I can't figure out how to get into the archives, either. I know that this topic has been done and done, and I ignored them all because I thought one of the more freguently posted solutions (sigma magnet, squished on) was working. I've started to notice though, that my speedometer drops out intermittently (you know, 20 mph, 9 mph (oops), 20 mph), and I'm beginning to believe that the sigma magnet, while a simple and elegant solution, just isn't strong enough to work with my computer (Specialized P-Brain).

A cateye magnet might work better. It does need slightly "opened up" but is a fairly nice solution.

doesn't seem right. Do they come in different sizes? I can't get the blade in the one side with the screw, and the other side, without the screw, is too loose.

The Cateye magnets are designed for conventional spokes, but with a little, uh, gentle persuasion, they'll work on the K-spokes. All that magnet has to do is stay snug without tweaking the spokes, and in the same position relative to the sensor. Use a bit of electrical tape to snug up the non-screw side. There's no problem taking a blade to the magnet mount and carving it up a bit to make it fit better. I've ordered two or three at a time through the LBS so there's room for a slip-up. They are cheap. I've used Cateye magnets for several different computers on several different wheels.

One of the boys at the shop suggests cutting any sort of soft type magnet to the width of the spoke blade and using something like RTV/silicone to adhere it to the blade. I'd tape the magnet on to the spoke for a ride or two just to see if it works with your computer.

just to jam the thing on with the spoke smack dab in the middle -- right under the magnet. Not terribly elegant, but it seems to work fine.

That's exactly what I did. I have some sapim x-ray bladed spokes on the front wheel in a radial pattern so I just took the standard cateye mount and put the flat blade right behind the magnet and screwed the set screw in tight. The bladed spoke keeps it from rotating around the spoke.

An alternative was to try my old Specialized spoke which is basically a round eye with a screw in the back, made to screw onto one spoke no matter what the pattern, the slot for the blade was too small to fit but I imagine with a fine sander, you could probably widen it a bit to fit.

Just go and buy one of the ones made by Mavic for the K's. They are not that expensive. Just go to a bike shop that has one in stock. I made the mistake of having one ordered in the freight cost more than the !##$en magnet
