I just took delivery of a new gravel bike frame from a smaller manufacturer. I had ordered a frame that had 100x12 front spacing and 142x12 rear spacing.
The thru axles were included in with the frame. Upon measuring the frame, the fork measurement measured from inside the dropouts is 110mm and 155mm in the rear from the inside there as well.

I'm kinda confused about thru axles as this is my first foray into these, is this normal?

Thanks
