Tree Frog 15x10mm Boost Spacer

The Boost Spacer is handy, if you have bikes with 15mm thru axle systems, with both 15x100mm and 15x110mm. There's no need to change the fork mount on your bike rack! Simply insert your skewer through your fork and 15mm fork mount, then when the bike already has some support from the fork mount, place the spacer in between end of the fork mount and the fork, then push the skewer through and fasten.
