This might not be the ideal place to post, so apologies in advance!

My touring (light touring!) bike doesn't have quick release wheels and I wondered what tools people carry for quick removal of wheels? In the past I've carried an adjustable wrench/spanner but this isn't great for the bike. I've also carried around a handful or proper spanners but the weight starts being prohibitive.

Any cool tools or tips? Or should I just change the axles for QR??
