Mavic Speed Release isn't backwards compatible with standard thru-axles, so definitely don't spend that $150. It won't work on your bike if your bike doesn't already have it. Ditto the RATS system, or any of the other "quick release" thru axle variants. If you've got thru-axles that screw in to threads in the fork/dropouts, you're stuck with thru axles that screw in. Fastest/most convenient thing IMO is to carry a tiny ratcheting bit holder with the correct size head in it, and use that to screw the axle in/out.
