I'm looking for an upgrade to my crankset and I would also like to replace bottom bracket. My current setup is Shimano M522 (3 x 10) which I would like to replace with SLX M677 (2 x 10) and current bottom bracket is First R30. Are there any compatible bottom brackets from Shimano that can fit in my bike frame (73 mm wide) and which will be compatible with SLX M677 crankset? Shimano recommends BB-MT800-PA as compatible press fit bottom bracket but according to specifications it is available in 89.5 - 93 mm.
I'm confused about options and alternatives - please help.
