I have a gravel bike with Advent 1X9 speed and it works great and I like the shifting design (the levers) very well. Much better than Shimano and on par with Sram for my liking.

The only thing I would like is if they were compatible with Sram/Shimano 8 and 9 speed MTB and cassettes like other Microshift offerings. Not a big deal, but it would be nice.
