This will be unecessary advice & cautionary tale to most, but I got caught out on a ride yesterday when the cleat of my clipless pedal came loose. Needless to say I felt daft, and was very lucky to find the bolt and washer again on the road!
Luckily I found some other kind cyclists who were able to offer a multi tool with allen key to fix things. Cheers my friends
I will be checking tightness more regularly in the future, and am off to by a multi tool....
