The good news is that unlike so many modern devices--which simply stop working and our discarded--bicycles can be repaired and made to run like new for decades.
We can't tell you what a shop that charges $35 or $45 for a tune up does for that price.
We can tell you what our mechanics do at Trophy Bikes. We start by inspecting the bike before it even goes into the back of the shop. We identify any damaged or worn out parts and figure the least expensive way to repair or replace them. We keep hundreds of replacements parts in stock--but if there's an unusual part and we need to order it, we do that right away.
When your bike goes up onto the repair stand, our mechanics start by wiping everything down--it's easier to work on a tidy bicycle.
Then.... We remove both wheels and true the rims by carefully adjusting spoke tension; we clean road dirt and oil from the braking surfaces of the wheel rims; we inspect the tires and fill them to proper pressure; we sand the glaze off brake pads to expose new material that will grab better; we check and tighten every fastener on the bike as needed; we lube cables, chain and other moving parts as needed; we adjust brakes and shifters as close to original factory specifications as possible; and finally, we test ride your bicycle to double-check that it's working perfectly.
We charge $69 in labor for all of the labor above--that's about 19 cents a day for one year, and for most bike commuters, one tune-up per year is plenty. Riders who carry cargo, who park their bike outdoors full time, or who like to push their machines hard (you know who you are!) may need service more often.
Then there are sunshine cyclists, who just ride for fun from time to time; they may not need all the work in a full tune-up. For them, we suggest a Safety Checkup--we adjust brakes and shifting, lube the parts that need oil--and again, check every fastener on the bike, to make sure your ride will be safe in traffic.
The Safety Checkup is also a favorite for people putting a bike back into service after a long period of storage or when a bike has been shipped; even if it was in good condition, it's a good idea to check everything before riding in traffic again.
