I would love to see an isis conversion for 40mm bearing unis that use square taper to ISIS! This would allow the use of crank spacers to squeeze the bearings into the inside of the frame and not slide around that 1mm gap in the bearing holder. The crank spacers would make a bolt on bearing cap caliper mount work for a disk brake more consistently on frames intended for square taper. will these bearings only work in lollypop holders?
