As unforgiving as Flandrien, these barriers will teach you how to really commit to the barrier without taking up half of your garage.
Simply stake into the ground and throw in a 2x4 and you have Belgium in your backyard. Add additional tent style stakes for extra stability. The five height options will allow you to progress up to the UCI legal 16" barrier height on your own schedule. No need to ask Carpenter Uncle Bob to build a set for your local CX race because these are also sturdy enough to be used on the course.
A must have for true Cyclocross training!
PS. It also has a bottle opener......
