Yes, there is a clutch lever. seems like a larger pulley wheel. The mech mounting bolt is screwed directly to the hangar(like SRAM mech). Is the cassette from shimano? judging from the ramp profile, it looks like a shimano, a 50T/49T and still 11s (might be a prototype). Chain has a quick link. With freeza rotor, finned pad is a dud. Caliper is a mono body, looks small but beefy.
