Installation

If you purchase a Sigeyi AXO or AXO SL spider, installation requires that you remove your current crankset, replace your spider with the Sigeyi and reinstall your crankset. For certain cranks, a Sigeyi Lock Ring Tool is necessary to remove the spider. If you purchase a complete crankset, you simply remove your current crank and install the new one.
