Left side insert for IRD Sliding Dropouts. Flat mount installs inboard of seatstay, not chainstay. 12mm thru-axle compatible. For 140mm rotor (add adapter to fit 160mm)
Allows older thru-axle compatible Soma Wolverines, Juice and Riff frames to use flat mount brakes.
(Note: Rohloff hubs are harder to set up with flat mount brakes. Stay with the IS dropout insert if running Rohloff.)
