It was indeed cheaper to buy a new brake than the hose, bleed kit, fluid and new brake pads. Crazy eh.
It’s a medium, and at 5’10 it suits me. It’s longer than the 45650b and the reach is about 4mm more. It feels more stable and doesn’t feel any heavier than the 45650b did.
It’s very quiet and with a lower bb feels a lot more planted when cornering. Climbs a lot better seated as there is more traction. In summary I love it so far.
