Computer Magnet for Ksyriums(11 posts)

Computer Magnet for KsyriumsEvan

Does anyone know of a magnet that will fit on the
larger spoke of the ksyrium, or can a normal magnet
be forced to fit?

for everytime I've posted an answer to this question ...

I use Sigma Sport wheel magnets on Ksyriums. The work with my wife's Flite Deck and well as my Sigma Sport computer. Carefully push it onto the spoke and through a rib in the middle, but not too hard or you'll break it. Then slip the metal sleeve over the magnet. I think these things are designed for bladed spokes. They work great and really stay put. They cost about $5.

Run a small drill bit through the slot to enlarge it slightly, then slip the sleeve over the like a charm (courtesy of Branford Bikes)

For single impulse computers, the Cat Eye fits the Ksyriums and if you use an Avocet computer, their ring for a 28/36 spoke front wheel works although you'll have to cut off the clips.

I got a CE at the lbs, which spans two spokes. It actually opens up & is fit across the spokes & then screwes down on the ends of the unit. I had one of these on my old bike & it always worked without problems, although it's not the cleanest look.

Funny that this continues to be an issue....doesn't seem too complicated?!

Strange coincidence--I opened this forum this morning intending to post a request for help finding a Mavic Ksyrium magnet. I've got an Ergobrain, and I'm getting inconsistent speed and distance readings, so I wanted to eliminate the magnet as an issue. I'm using what I think is a Cateye (plastic, fits where spokes cross), which seemed to work, but the original Campy magnet (which also may have been a Cateye?) is pretty big, and the replacement may not have sufficient force.

The LBS has had them on backorder for months, Colorado Cyclist is out of stock. I don't have the Mavic part number here.

So, if anyone has or knows where a Mavic K wheel magnet is for sale, I'd appreciate hearing about it. Thanks.

I have a Vetta RT-77, and the supplied magnet is a pretty big disk, attached to one spoke with a set screw. I was using Sigma magnets on another wheelset, mainly because it has bladed spokes, but at anything above maybe 5 mph, I'd get intermittent or no reading. Due to the design of the Sigma attachment, it's impossible to place the magnet closer to the sensor, at least on a bladed spoke, so my solution was to remove the rubber surrounding the magnet, and tape it onto the outside of a spoke. This narrows the magnet-sensor gap considerable, and doesn't look half-bad, either. On a Ksyrium, with their black spokes, it'd all but disappear.

I located a small rectangular magnet at the hardware store. I is the same width as the spoke and about 1/2 inche long.
A dab of silicone seal and some 3m electircal tape and it has all but vanished.
Try prying one of the small magnets out of the letters kids stick to the fridge!

Buy two magnets. Put them on opposite spokes. Read cyclometer. You'll be going TWICE as fast!!
