Split 30 cranks combine the stiffness and reliability of a 30mm-diameter spindle with the versatility to fit on a wide variety of bottom bracket shells. One spindle half is integrated into the left crankarm and one into the right arm; a bolt connects them together in the center so that ramped crenellations on the end of each spindle half tightly engage each other and a spacer in between to obtain proper total length.

Congratulations on your new bike. We hope you get many years of riding on this bike. Your Zinn, Clydesdale, or Tui bike has been assembled with care by one of our seasoned professional bike mechanics and checked off by our team. We ensure all components are installed properly, shifting is tuned, brakes are bedded in, and brake calipers are centered and adjusted. We warranty the assembly of your bike for 3-months from the date of delivery. If you find any issues with the assembly of the bike, please submit a service request form here and we will determine if the issue is due to a mistake in assembly or due to normal riding. If you live on the Colorado Front Range or are in the area, you can bring your bike to our shop for service any time. Be aware that bikes encounter a great deal of vibration during shipping which can cause cables, bolts, and threaded components to loosen. It's important to check the tightness of everything on the bike before the first ride, and it's normal for shifting to need minor adjustments when the bike arrives.
