I would just like to thank you guys for your patience and help, especially in the weather conditions.
Yeah, my bad on the chain, it's my much abused winter bike (third winter for it, it's been cleaned/lubed twice) and one too many clumsy changes.
The seven holes in my inner tubes I blame on the Muppet who left the road covers in thorns. Two spare tubes is a cheaper choice than "get a normal bike" suggested
.
Thanks to
@DougieAB getting new one I was able to avoid a long walk. I owe you a pint or six in the Lakes.
