If you have bladed spokes (or possibly in any event actually), no matter HOW MANY times you have interupted your ride to try to get you computer working properly as a result of apparent sensor/wheel magnet hassles, DO NOT be tempted to jussst reeeeach down and knock the sensor a little to save stopping YET AGAIN, otherwise, if you suddenly hit a lump in the road, you may learn that bladed spoke + carbon fork = very effective thumb shearer.

3 1/2 hours in A+E is a really bad way to end an otherwise excellent day's ride.

Not smart I know, but easily done when you just don't want to stop AGAIN, and you have done it a dozen times before with no problems. Still, now I know why they are called bladed spokes...

Also, don't try (or try only if you are sure your health insurance is paid up):

*"Brushing" your rear tire with your foot.

*Looking 180 degrees behind you while on aerbars on a curvy road

*Riding without glasses with lots of bugs flying around

*Removing your shirt while on rollers

*Making a u-turn with a flat front tire

I can't get the image out of my head of falling off the rollers with your shirt up over your head and your arms still trapped inside the shirt! Too funny!

I went out to meet a club mate for crit practice in an empty parking lot. He got there early and was already into it. I rode up behind him and called out just as he reached down to brush some debris from his front tire. He looked back to see me & instead of skimming his tire, jammed his thumb between the back of the fork crown & the tire. By the time he got it out, the tire had sanded a groove into his thumb nearly down to the bone. Strangely, it never really bled, but was sort of cauterized. Hurt like heck, though.

The November issue of Cycling Plus Magazine (Page 58) has a blurb about a new magnet from Sigma, which "will fit virtually any steel spoke round or bladed". I didn't see anything about it at the Sigma Web Site, but you might check with your LBS. Worth a shot (or at least a finger!)

I have a feeling that I might make that a priority after yesterday's events - my thumb is bleading through the dressing onto the keyboard as I type...

don't stick your finger in the wheel whilst moving!!!

Would work for you, jelly legs...muncher

At the speed you were going yesterday,

1) you would have had time to pull it out before the next spoke crept round; and

2) aow would you have known if your speedo was working or not anyway?

(I'm getting the most our of your bonk day, it's a guinea a minute)

It's raining in San Francisco today - can't ride, not much to do...

I have the same problem with the sensor on my bladed spokes. Do you have any fixes? I was thinking of putting something in there to take up some room or possibly some glue. What do you think?

Just Saturday during a huge, fast pack ride here, some complete idiot in the middle of the about 100 person pack starts looking back and fooling with his rear brakes. Needles to say, he had about 20 guys behind him immediately yelling at him. Talk about the parting of the Red Sea right behind him!

Funny thing was, the one I have (sigma sport) has been working fine - I just "jammed" it on to the spoke at an angle (it has a sort of "sleeve" you slide the magnet into, trapping the spoke in between), and moved the fork sensor to it as needed. Yesterday however, the computer was playing up, and I thought that it might be the magnet position - so I moved it and it worked for a while, the stopped again, then ditto till I had the thumb v spoke contest which ended the day's riding. Could even just have been the battery - who knows, it'd been fine till then.

The sigma has a rubber band type fixing on the fork sensor, so you can position it pretty much anyway you like at an angle with a bit of fiddling, as opposed to the ones on a plastic clip bracket. That means I didn't have a problem really.

Interms of fixing to the spoke, I would be tempted to just use a little tape if you can get the sensor near enough, or some epoxy glue if you need the sleeve/magnet holder to make it stand out from the spoke - depends on your sensor mount design.

That or the device on the post above - not seen those. Must be 1000' of Special K owners with them out there somewhere...
Trek makes a magnet to fit rolf bladed spokes ....cyclinseth

It secures very firmly, but it doesn't look like it would fit a wider blade such as the ksyrium type.
Cateye makes one to fit the Rolf's, too (nm)dsc
