Stages or 4iiii on a Trek Speed Concept

Looking at either a Stages or a 4iiii dual sided power meter option for my Trek Speed Concept. Trying to see if anyone can speak from experience for the clearance for either Stages or 4iiii on an Ultegra 170mm crank setup on a current gen Trek Speed Concept.

i have a 4iiii left-only on 170mm cranks on my large SC.
originally had a custom placement of the pod to ensure clearance but when i had an issue with it they sent me a replacement standard model as they thought it would be fine despite theoretically not having clearance and i needed it urgently for a race - really good customer service and has been working well since, would recomend

Thanks for the data point. I have a medium size speed concept and wonder if that would change the figment. Are your cranks Ultegra?

I have a Stages on my SC, Ultegra 170mm crank arms and no clearance problems.

Excellent. Thanks!

X2, medium too

Now that is great to know. Same size as me.

Did either of you take your own Ultegra crank and send it to them or did you buy a new setup from them?

sorry only just saw this! i purchased from a shop no need to send away

I just bought the Stages PM crank arm that matched my crank. Super easy. No need to send in your crank or crank arm.
