Quadratec Car Rack Accessories Editorial Review

The Quadratec Top Tube Y-Frame Bike Rack Adapter Extension Bar is a great accessory for transporting bikes on a bike carrier, especially for step-through or fat tire bikes that don't have a normal horizontal bar. The tube is fully adjustable and doesn't scratch the bike. The rack has hooks that slide down onto the cross bar to lock the bike in. While it allows to secure the bike adequately, it does not come with the option to lock the bar to the exact length needed to bridge that seat post to neck distance.
