I bought a CatEye Strada wireless computer (new slim design), but it requires a maximum of 5 mm between the sensor and magnet which I think is pretty standard. The Big Dummy has about 50 mm between the nearest spoke and fork -- ain't gonna work.
I'm looking for simple functions with preferably a wireless unit.
I did a search and didn't find anything on the forum.
Thanks.
What is your wheel set up? that is almost 2 inches from spoke to fork. A buddy of mine has the Planet Bike wired 9.0 on his BD and no problem at all. There is a wireless version of it as well. It has to be mounted close to the dropouts, where the spokes are closer to the fork.

put something behind the sensor. shims or whatever. I had this issue on my pugsley.
CatEye used to make an extra strong magnet for this purpose, but I don't see it on their current web site. Vetta makes a magnet that sticks out further from the spoke. Big, ugly thing and it's supposed to be for bladed spokes, but I've found it works just fine with round ones too.
What about mounting it down near the hub?
I use a Filzer wireless computer and have no issues with the sensor and magnet being close enough on my Big Dummy. When you attach the sensor just rotate it around the fork blade until you get the desired distance from the magnet. The closer you are to the bottom of the fork blade the smaller the gap will be to start with.

Agreed with Vik. Just rotate that sucker.
I'm using one of the new Niterider Rebel computers, the 3.0 wireless version. Works great on my Dummy.

Thanks for all the replies and suggestions.
The instructions say to mount it as high as possible on the fork -- but that sounds like a non-issue as even the bottom of the BD fork will be within the max range from sensor to computer (though I did mount a wireless low on a previous mountain bike fork and it sketched out). Sounds like low on the BD fork will be fine.
I didn't want to bust open the package, use the zip ties, mount the thing, have it not work, then try to return it. Don't want to abuse the liberal REI return policy.
