    150-160mm crank arms

    Doing a bbshd bent trike build and would like to try out shorter crank arms. I've seen an attachment that has three spots to attach the crank arms but don't remember where I saw it, I've searched here and cpl other forums I frequent but have found nothing. I've also googled for this adjustment part & short crank arms but virtually all only have the left arm for sale. Any help steering me in the right direction would be appreciated.

    Google unicycle crankarms, there are lots of different sizes. I buy steel at $15 a pair for experimentation purposes and then replace them with alloy once I found a size I like. FWIW I worked my way down through 140mm and now run 125mm on my pair of FatBikes. The FS fatty will run 75mm cranks: more like rotary foot pegs really......
