2018 Cannondale Synapse - distance between rear dropouts

[weisan]

I am currently working on a 2018 Cannondale Synapse.

When I put on the rear wheel, it seems like there's a noticeable gap between the dropout and the axle, wondering what's up with that. My caliper measures 143+mm between the dropouts, is that normal?

Google AI says, "The rear axle spacing for the 2018 Cannondale Synapse is 12x142 mm (thru-axle)."

Thank you merckx pal.

As it turns out, the issue lies with getting the proper Thru Axle lever "authorized" by Cannondale.

143mm is still within acceptable range.
