I thought I’d try here too. I volunteer at a small local bike park. We’re currently planning our “expert” jump line. The top ramp already exists on our intermediate line, 4 feet tall with an 8 foot radius, 9 foot gaps. These work well on 20″ and 26″. Didn’t try it yet on anything larger. If anything, I think I’d prefer them to be a tad steeper on my 26″. How do the other two look? Mainly the bottom. I think it’ll work, my building partner thinks it’ll be too steep.
