Thoughts about square taper vs Ultra-Torque? Looks like I have a choice between carbon Record 9/10 cranks w/ square taper, or carbon Chorus 9/10 w/ Ultra-Torque.
I'm slightly leaning toward the latter, since there aren't any sq taper cranks rolling around the Parallel Universe pro peloton in 2019. But if Ultra-Torque will make my C&V spirit disintegrate or require thousands of dollars in specialized tools . . .
