I have in the past worked out where the VPP is for other reasons, this pic shows how.Nice to get into your thoughts and various travails of getting the tension right. I did wonder, since some eccentricity woudl I assume help with the smaller loop…
With a head full of virus…and brain working like a clunker…I indeed had thoughts of ‘how do you find the pivot point in a virtual pivot context?’ - I should immediately have realised that on single pivots, and with helpfully higher pivots away from inference with chainrings, the pivot point is er…stunningly obvious.…apologies
….and the forward facing caliper mounting….well……reason one is to stop interference with mudguard stays. Which is sensible…since it can involve a hell of a lot of spacers and long bolts on SKS mudguards, when the caliper is in the conventional rear-and-left position on forks. Reason two {from Cotic) is that ‘it does not produce a wheel ejection force’ - which does make sense in terms of dynamics … but which of course they obviated on the Mk2 by having closed 10mm bolt thru dropouts...
I've never heard of a wheel coming out of a fork due to the braking force, but I do know that brake mounts are put behind the thing they're attached to (mainly on the frame) to add strength in the direction the brake caliper is being forced (which is why frames also have braces between the seat and chain stays), so with the caliper mounted at the front of the fork, all that's holding the caliper there is the two 5mm bits of metal around the bolts.
