No price is listed on the Dust Riders website but a google indicated they were about $250US
•Weight: 4.3kg
•Dimensions: 49 X 21 X 5 CM
They can also be used as a bead breaker, or as a center stand to removing tyres
I can see somebody coming up with a home built version before long. If needed, it would be a godsend.
