Is the Shimano BB-ES300 compatible with Octalink v1 and v2 cranksets?

The BB-ES300 typically uses Octalink v1 spline geometry. Octalink v2 cranksets have deeper splines and will not fully seat on a v1 spindle. Check your crankset box or spindle for the version designation before ordering.

Can I use this BB on a road bike with a 68mm shell?

The BB-ES300 variants listed here have a 73mm shell width designed for MTB and trekking frames. For a road bike with a 68mm shell, a different spindle length variant is required — consult Shimano's compatibility chart for the correct BB-ES300 specification for your application.
