Because they can. I had a guy in this morning who'd had his barrel adjusters stolen from his brake levers. Cheapo brake levers at that. The funny thing is that it wasn't the first time someone had come in with that particular problem.

Keith-thanks for the help this morning. A trip to crappytire, 2 m10 nuts, a tube of super glue gel and some ingenuity has solved the problem until the americans finish their holiday and get back to the warranty dept.
