I'm sure it's not ideal for the long tubes as I'm sure they could bend pretty easy but it's the only suspension I for on this death machine so I'm gonna trust that it's gonna work. I imagine the realy long bikes kinda use the flex of the tubes for suspension. Some of them are just long tubes with no suspension at all. My first fast ped was a rigid and I realy never had any issues with it. It had the cheap ebr forks that realy did about nothing. The thing handled realy well. Felt more connected to the ground. I guess when you build a performance suspension you make it considerably stiffer so makes sense. Not saying this chopper is a performance machine but it's not gonna be slow by any means
