Is there still a plan for another run of these?
I'll be making up a group buy post for second round soon.
In the meantime, here's my first draft of a fitment template:
I think its accurate within a couple millimeters, though might still need some adjustment. As mentioned in the template itself, the dashed line includes the additional 3mm offset from the caliper, though it’s obviously only as good as the CAD model of the caliper I built from measurements
Tested it on my snow wheels which are tight to the corner at the base of the spokes where I expect. Haven't had a chance to pull the Dekagrams off and test it against those, which should be the real test, as they should just brush the 3mm line all up the spokes.
I recommend printing it on cardstock, or gluing or tracing the pattern to cardboard to make it easier to handle.
