Boom! Yes, on my wife's hardtail we run a 26t Wolf Tooth granny mount narrow wide and a Blackspire granny guard. Looks clean; she's very happy with the gear range. They move the chainline outboard from a standard granny so you still need spacers to make the chainline sweet, but the quality of the ring is excellent.
Very surprised with the number of 104/64 cranks out there that more companies don't offer 26t and 28t granny mount n/w rings.
Race Face is doing this with a 24t ring and small bash
