    The cranks are designed to specifically for 68mm wide BMX bottom bracket shells and require no spacers. Spacers may be required if your frame has a bottom bracket shell that is less than 68mm wide.

    No. A chainring can only be installed on the inside of the spider.

    No. A loose pedal will damage the crank and can cause injury. Always ensure that your pedals are tightened correctly.
