15x100 Thru-Axle Fork Mount Block
A bolt-down fork mount for a 15 x 100 mm thru-axle bike: the 99 mm wide crossbar slips between the fork dropouts and a 15.3 mm teardrop bore takes the axle, so a van floor, truck bed or plywood work stand gets a real fork mount instead of a $50 machined adapter. Base is 104 x 52 x 6 mm with four M5 clearance holes on an 80 x 38 mm pattern; axle centre sits 40 mm above the deck, gusseted fore and aft against fore-aft tipping. Boost 15 x 110 forks add a 5 mm spacer per side.
