Putting skate board wheels on crash bars is nothing new  and we are not trying to re-invent the wheel here. We are just offering an easier and stronger way to do it.  This adapter allows you to add the skate wheels to any crash bar with 1/2 bolt holes in seconds.  Low profile design keeps it from your crash bars from getting too wide and utilize a 1/2-13 grade 8 bolt for maximum strength. The full sleeve design allows you torque them down to the correct spec all while supporting the bolt for maximum strength. These DO NOT spin and there are NOT  bearings in the wheels. They are solid mounted. spinning wheels is already a thing and not what we are trying to offer. 

SOLD IN PAIRS WITH BOLTS WHEELS ARE NOT INCLUDED
