There was once upon a time that manufacturers covered the LBS labor for their warranty work. I saw the paperwork on a Cannondale back in 1995 that covered new parts and the labor.

I know Trek will no longer pay for labor on their "lifetime" frame warranties and sticks the customer with the the shipping charges as well. My next new bike will not be a Trek. Litespeed no longer honors their lifetime frame warranty and probably the same for many other companies.
