The Pro 1 & L1 Front Wheel Holder combo package helps you to carry all road types of bike or mountain-bike, and placing the front wheel next to the rear wheel on top of your car. The package comes with a Pro 1 double layer deck, 1 fork mount size 9-15x100mm fork mount and quick release(or you can choose 1 different fork mount from our chart, no additional fee to swapping the 9-15x100mm fork mount out to the fork mount you request), and the L1 front wheel holder, with a metal front wheel carrier and 1 Velcro rear wheel holder.
If you choose the 9-15x100mm fork mount, when you transport a 15x110mm thru axle mountain-bike, please remove the 9mm plugs from the fork mount, and the 9-15x100mm fork mount becomes a 15x100mm thru axle fork. You can order a Green 15x10mm Boost Spacer from the accessory page, to add to the 15x100mm fork mount, to boost it to 15x110mm size.
To transport a 12x100mm or a 15x110mm thru axle front wheel on the L1, please use TreeFrog 9x100mm quick release to secure the front wheel to the L1 metal front wheel carrier.
