Shimano Altus FC-M311 Crankset (Black) (3 x 7/8 Speed) (Square Taper) (175mm) (48/38/28T)
Original triple crank was getting long in the tooth and starting to slip under load. Replaced with a similar crank, except that the arms were 75mm and the originals were 70mm. Thought I might notice the difference, but happily saw no difference while pedaling. In any case, the fit on my 2017 Trek FX.2 was perfect and easy to install.
