This is the new upgraded crank system as fitted to the 2019 Nimbus Performer Giraffes. The cranks have had a total redesign, they are now made from super strong 6061 aluminium with a tough anodized finish. The crank comes with a steel bash guard to protect the sprocket from drops and keep your trousers away from the chain.
The cranks are supplied with the latest sealed cartridge bearing bottom bracket (spindle). This should improve the pedaling action of the unicycle not only by being a smoother bearings but also places the chain in direct line with the sprockets at the wheel end of the chain so ensuring sweet ride at all times.
