Ok here are the specs on the screw for the fidanza wheel. (from tech support)

"IT IS A 1/4" 20 X 3/4 SET SCREW. IT CAN BE ADJUSTED
WITH A 1/8" ALLEN KEY. WHEN INSTALLING MEASURE THE
SENSOR FIRST WITH A VENIER CALIPER THEN MEASURE THE
DISTANCE FROM THE MOUNTING SURFACE TO SET SCREW. ALLOW
FOR.030 CLEARANCE. MAKE SURE THE SET SCREW GETS
LOCTITE ON IT."

So I have 3/4" to play with.... so I will get at her and let you know how it goes.
