New!! This simple disk bolts to the Kris Holm Spirit cranks - you slip the axle bolt onto the Rollo Disk and then tighten the axle bolt into the crank.

It turns the Spirit cranks into superb flatland cranks by enabling a huge increase in stability for crankrolls, without any need to produce specialized flatland cranks.

Several riders in Europe and the U.S. have been testing it over the last few months with great success and they have all noted a big increase in their consistency for tricks.
