Will Dearborn said:My buddy took his bike in for a full tune up costing $50.
Specific complaints:
Disc brakes have little stopping power.
Chain rubs on front derail.
Crank arm becomes loose frequently.
When he picked up the bike, the brakes still sucked. Shopkeep says
that is normal for discbrake power. Although I have the exact same
brakes and his are about 25% effective.
Replacement of pads is usually the only remedy for what seems to be weak
disc brakes. Sometimes you can cook the pads on the stove to burn off oil
or other pollutants, and they'll be good as new.
Quoted message said:Shopkeep says it is normal for chain to rub on derail. Interestingly
enough, it didn't rub when the bike was new.
This is related to the crank arm issue below.
Quoted message said:The crank arm tightened at the LBS fell off later that day. Upon
inspection, it turns out the crank arm is ruined. The shopkeep didn't
notice.
The crank arm was ruined prior to the bike ever being brought to the shop.
The shop did what it could, but the crank arm was beyond repair. Whoever
was responsible for that is unknown, but there would have been an extra
charge for a new crankarm whether or not the wallowed-out one was tightened.
Since it was wallowed out and moving all over the place, it is of course
natural for the chain to rub against the front derailleur while pedaling.
Quoted message said:Alot of people here work in shops or have friends that do, so is it
standard to jerk people around? Or is it just my area? This is not
the first time to be told stupid things inside a bikeshop.
It sounds like the bike may be a Walmart bike, because disc brakes and
square-taper bottom brackets on the same bike usually indicate this. There
are some exceptions, however.
The shop was wrong in charging your friend $50 that did not fix anything.
Chances are good that the person who took the bike in, the front counter
person, is the person to blame, as sometimes they know little about the
mechanics of bicycles in general, and just take bikes with broken or
deteriorating parts in and make the mechanics deal with it.
Your buddy should have been charged only the price for the things that got
fixed. He should ask to speak to a manager and raise hell, especially if he
dictated exactly what was wrong with the bike before handing it over to
them.
