L/S 105 5800 (Stages) crank on a Tiagra 4600 crankset?

[nickAKA]

Ignoring the obvious weight & colour discrepancies, should this fit? Is it the same pinch bolt fitting/star pattern stud across the Shimano range?

Thank you kindly!

 

[DCLane]

Yes

 

[nickAKA]

Yes

Much obliged!

Check the crank arm lengths match (170/172.5/175mm etc).

On it like a car bonnet...

Probikekit said it wouldn't fit which was a bit weird. Possibly squeamish about the weight difference?

Sensible, but most people wouldn't notice the difference.
