Disclaimer for the lovely Bike Chain people, the nature of what I need, a new brake cable, my current one seeming spongey this morning and investigation showing some serious fraying, meant I couldn't ride down to you.
So it was off to the nearest store by foot, MacDonald Bikes.
"Hi there, I'm just after a brake cable, a barrel-ended one."
Look of uncertainty, after I break up the three-person-staff-chat that had been going on before I walked in, "Right, inner or outer."
"Inner."
"There are loads of different sizes. Different barrels y'know."
"Yeah."
"We've got loads of different types."
"Well... Could I maybe have a look, I know what size it is to look at it..."
"But they're all over the place in the workshop. Y'know. They're like gold dust."
"Okay. Well I guess I could go back and get the old cable and bring it to compare?"
"Yeah."
"Thanks then." And I headed up to BikeTrax, who still had none on display, but fetched me one from the workshop.
Don't know why I ever bother with MacDonald Bikes, they really do never seem interested at all.
