Switch was developed to reduce the cost of replacement chainrings, increase compatibility with new offsets and make the process of changing out chainrings much simpler
Quick Change allows chainring replacement in less than a minute with only a 4mm allen key. Simply loosen the bolts 2 turns and unlock the ring by rotating it 20 degrees and then pull it off the crank. Reverse these steps to install a new chainring.
Regular chainline = 49mm
Boost chainline = 52mm
Super Boost chainline = 56.5mm
