Is this really how it is?

You might invest in a $12 chain checker tool. Then you can check your chain wear yourself, no need to have the shop do it.

Or even cheaper, get an ordinary ruler. Lay it against the chain, and measure the chain along that length. A new chain should have the pins centered on the 1" and the 12" mark. When that measurement stretches to 12 1/8" or longer, it's high time for a new chain.

I've had good luck with the wheels so far, but have gone through at least one derailleur hanger last winter after a close encounter with a pine tree...
