I’d buy one in a heartbeat.
The Bike Chain had one back in the day, went for a mince around and it felt like a riot.
Aside from stair-set cobble mincing, not a clue. Nice green in 1.0 and excellent kit in 2.0.
Edit: 1.0’s full of SRAM, 2.0’s full of Shimano. Your poison ,your peril but SLX wins for me.
