The shop I worked for charged $50 for that "Ride Ready", and included tire mounting in that cost. Our tubes were $7.62 with tax each? So yeah, in other words they raked you over the coals pretty bad. I doubt the 89 included servicing the Bottom bracket, hubs, or headset. We charged $15 extra for each lube point, but hardly ever did anyone say sure, I want my bike to last longer. 99.9 times out of 100, they wanted it to look good, and stopped short of anything more than a basic tune up.,,,,BD

Our $50 was..


Clean the bike front to back and top to bottom(pressure washer)
Adjust derailleurs
Adjust brakes
Adjust headset (if needed)
Adjust hubs (if needed)
True wheels
Check all hardware for tightness
Lube chain
(etc, if needed)

Labor for cables was covered under the tune up, but the cables/housing was charged.. I did however, get a 10% commission, so selling
parts was a good way to make more money. I was fair about it though, and only sold things that were actually needed.
