Buying new thru axle road wheels - What do I need to know? I got a crazy good deal on a 2018 Cannonade Synapse - So much so I didn't pay attention to it having huge wheels/tires (21c rims and 30mm tires) until I got home. So now I want to swap out the wheels so I can run smaller tires.

Iv'e never dealt with a thru axle before - What do I need to know when buying wheels?

The axle has a lot of numbers on it
Rear: 17 L4 QR51X-12-160-P1.0-16.5
Front: 17 L1 RQ51M-12-125-p1.5-10

Other than knowing it is a 12mm axle, do I need to pay any attention to anything else? Didn't know if there was a width measurement or anything I needed to deal with.

Would I just use the axles that came on the bike with different wheels, or will I need to buy new axles?
When getting the same 142x12 and 100x12 standard wheels I advise to take note of the following:


If your frame requires special dishing or not. Synapse probably doesn't.
Outer rim width. With wider rims, the rim clearance might become an issue. Not your case, though.
Rotor fitting standard, 6 bolt or centerlock.
Freehub body, 10-speed or 11-speed HG, Campagnolo or whatever comes out next (SRAM XDR, Shimano Micro Spline).
