Of course, most of us know a friendly LBS who will do the occassional fix - no charge. Usually, this is done by a shop owner who we know and frequent. Naturally, if work is done on a chargeable basis, however, even simple repairs can add up.
Two weeks ago I was in China going for a spin on my 28" wheeled, rod-brake single speed "Chairman Mao" style bicycle.
I store my bike at a hotel which I frequent. THIS TIME, I noticed that someone has been riding papa bear's bicycle when he is away. The brakes were worn and the left pedal was sqawking. No big deal. I am happy somebody is enjoying my bicycle hospitality. If it wears out, I will buy another brand new for $35.00
I brought the bike to a local repair man parked conveniently at the side of the road. He made the adjustments and repairs immediately - swift and competent. He lubricated a couple of points too just to be nice.
The total cost: 1 RMB = US$ 0.12. That's right - twelve cents!
I tipped him another twelve cents and was quite the dapper fellow in the neighborhood for my generosity.
