progressing upwards till you get a 5/8” hole to slide over the hex on the axle. If the
spat does not have a predrilled hole for the 3mm bolt/washer, then once you have
the 5/8” hole you can further align your spat then drill a 1/8”/3mm hole and install
the blind nut on the tire side and the bolt/washer and tighten using BTL. Now slide
one wheel collar onto the axle but do not tighten, now slide the tire on the axle.
