BLACK+GRAY Wheel Chocks
Recently, we built a simple 7' x 3.5' wooden flat-bed trailer to haul our "new" FZR400 race bike to Willow Springs Raceway. While we were trying to determine how to fabricate a wheel chock that would not only function but also look presentable found the PC-6 wheel Chock. We snatched the $46.95 up, and other racers have begun asking where we got it.
The PC-6 wheel chock is made from 3/16"thick thermoformed ABS, a high-impact thermoplastic. It has a
"box-like" construction and will take serious abuse before breaking.
With the highest point of the chock 8" tall it is impossible for the bike to roll over the chock. The 6"-wide wheel channel is also impossible to miss, even when you're exhausted and loading the bike solo. Overall dimensions are 12" wide and 22 1/2" long at the mounting flange. A smaller version, the PC-4, is available with a 4"-wide wheel channel for dirt or vintage bikes with smaller front tires.
Unlike the common tubular steel chocks that have a diagonal brace that endangers your delicate and expensive brake rotors, the PC-6 is shaped specifically so that it cannot touch your rotors. An additional feature the Black and Gray chock has over its competition is an entrance "bump." This bump does not hinder the entrance of the wheel, but does help to steady the machine while you're securing it to the trailer solo. Plus, ABS cannot rust as metal chocks will.
Mounting the wheel chock on the flat surface of the trailer was simple. We clamped it in place and drilled 10 of the 12 "drill points" provided and bolted it down, The instructions recommended "a minimum of six fasteners, not less than 1/4" in diameter."
Black and Gray also sells a quick-disconnect kit that consists of four shallow aluminum plates with 1/4-turn fasteners .... The plates are permanently mounted in the truck bed so the bed can be kept clear until the chock is needed.
The PC-6 wheel chock works well and is very sturdy. We would not hesitate using it on a heavy street bike or even a
