Aluminium Metal Insert (Adaptor) so that the same bearing can be used on the non-drive side for SRAM BB.
Note, this is where a 22mm SRAM axle chainset on the non drive side is present. Normally a 24mm bearing is used on drive side and a 22mm bearing with an extension is used on the non-drive side. If for instance you want to upgrade non-drive side bearing to stainless, ceramic or angular contact bearing, this inset can be used. Also handy if the 22mm bearing unavailable.
