This is a super fantastic tool for Roaduno riders or anybody with nutted axles. The ratchet fits perfectly underneath our hooded dropout making it super easy to loosen and tighten axle nuts. You can use a regular wrench too, but it takes longer. 

It's a little long for a tool roll, but you can magnet it to your frame with two rare earth magnets.
