Shimano drivetrain compatibility
No, that won't work! 8-speed and 11-speed systems use different chains. The 11-speed chain is narrower and doesn't fit the teeth of an 8-speed chainring.

Unless you get the 105 parts for very cheap, the usual advice here is not to perform this kind of upgrade. You'd probably find a whole new bike for the price of the items you'll need for a switch from Claris to 105.
