I don't think that's right. R-dubb designed these for his own bike which had an extended monolever swingarm - 100mm longer than stock, not sure on the shock length. Also, they were originally designed for the leg-to-axle offset of WP 4354 USD forks I believe. It's all in his design thread (which I'm too lazy to go back and check myself right now)
