henry james crown measurement

Anyone have a henry james fork crown at hand? What's the measurement from thecrown race shelf to the top of the brake hole on the front?

Thanks!

More importantly... is there a lot of variation on this? If I keep fork length constant, but switch what crown I'm using, is it likely that I'll have to get different reach brakes?

VRB- Too many numbers... I had to actually measure to refresh my correct memory. 1cm. Same as on the back side...

Most road crowns are within a few mms of this. But if you're pushing the last bit of pad adjustment for big tires and fenders you better do the math yourself. Andy.

Makes sense! I'll double check it before going ahead!
That one cm was from crown to the center or to the top?

Ok, bought myself one and got the official dimensions from Mr. James.

Andy is spot on with 10mm from the shelf to the center of the brake hole. It's 45mm clearance for tires, and you can get an extra 3 by trimming the tangs. It's also 10mm to the bottom.
