The Shimano SM-BH90-SBLS brake line has a longer banjo (Ice-Technology) and a short bolt. It is only compatible with the Saint M820 and XT M8020 4-piston brakes. The connection on the transmitter side is straight, the connection on the receiver side is made via the banjo. The stiffness of SM-BH90-SBLS is particularly high. Like all Shimano brake lines, it can be shortened without any problems.
