Its fair to say that I had to change the tube after this wee nail decided to come for a ride with me today… Picked up near the weir in Colinton Dell, below the Colinton Tunnel, for those who ride down there – watch out. (sorry for the shocking picture quality of the first two!)

kin ell! that's a proper man's nail.

whooosh, thats defo. a serious puncture you have there kit 😆

Good job you weren't running to work!

What tyres for industrial nails?

Tyre's a bit screwed anyway, but now has a bit of sandpaper reinforcement to keep the tube in!

are you sure someone wasn't trying to off you with a crossbow?
