I have a m675 right hand crank. Can I pair this with that crank?
Yes this should be functionally okay.

Can I use this to replace a Shimano FC3550 left arm crank?
25 Feb 2018
Can’t seem to find the specific part I need so wondered if this’d do the job? If not any recommendations for just the left arm?

Or possible full crank set upgrades that would fit if I replace the lot?
Hi there,

Please call our sales team to special order the suitable replacement left crank arm for the FC3550 chainset.

Will This Fit Onto The Shim Tiagra As A Replacement?
29 Oct 2014
I've been told to use a shorter crank arm on my left. I haven't been able to find a straight replacement in Tiagra, will this work?
how do you work out the length? is it total length or between centre points for the pedals and BB?

We do stock the left hand cranks for the Tiagra, they are SJSC part number 32039. In theory this Deore left hand crank arm would fit anyway but it would be a different shape to your current Tiagra one. The length is measured from the centre of the bottom bracket axle to the centre of the pedal axle.
