Karate Monkey Computer

[bschardt]

None of the odometer computers that I presently own work on my new Karate Monkey fork; the distance between the spokes and fork arms is too great for the sensors to reach, even after adding layers of thick, homemade shims. Ergo, the computer can get no data from the wheel.

What have other KM owners done to remedy this problem? Is there a computer that comes stock ready to overcome this gap? Ideas from anyone else would be appreciated as well... thanks.

How far down the fork leg are you mounting the computer? If you mount so the magnet is down close to the hub, there shouldn't be a problem.

I am using a Planet bike 9.0 The sensor is mounted about 2" above the axle. It works fine and is accurate.

I'm mounting it at the point where the fork is closest to the spokes, ie, right above the hub.

In case it makes any difference, I am running Salsa Delgado rims on Surly 1x1 disc hubs.

If you want I can post a pic tomorrow, Lemme know

Looks like I got it all figured out, folks. Thanks for your replies...

Another question... the computer only has settings for 700c, 650c and 26" and smaller wheels... how accurate is the 700c setting for 29ers?

The 700c setting is going to be at least 5% off from a real 29" tire. It would even be a couple percent off from a cyclocross tire, which makes me wonder ... are you really sure it doesn't let you specify the actual wheel circumference in mm or cm? I didn't know there were any computers that didn't let you do that!

Unfortunately, yes. It is an older computer, a CatEye Mity 3.

Approximation should be fine... all I really use the odometer for on MTBs is when I'm following instructions to a trail head, i.e. "about 4 miles from the turnoff..."

Thanks for the info...

All Cateyes, including the Mity 3, can be set to at least a 1cm accuracy. Do a roll out to get the circumference and input that into your computer. If you need help you can download the manual from Cateye's site.
