BIKE TUNE UP
Safety Check The mechanic will fill up the tires to recommended pressure, and check the safety and secure attachment of all the parts and accessories on you bike, making sure that nothing is worn or loose, or could contribute to an accident or fall.
Cleaning and Lubrication Your bike will be cleaned from top to bottom. The chain and other key parts of the drivetrain will be treated with a high-quality lubricant.
Headset and bottom bracket We adjust the external tension on the bearings inside the headset (between the handlebar and the fork of your bike) and the bottom bracket (inside the shell between the crank arms). These bearings, along with the wheels, take a real beating even during normal riding, and the correct tension on these bearings will maximize their lifespan. Even newer sealed bearing systems require servicing, including making sure that they are properly and securely retained, and some have a degree of adjustability.
Wheels We'll adjust the external tension on the bearings of both wheels, and dish the wheels, which involves aligning the rims perfectly in relation to the axle. Finally, we true the wheel by precisely tensioning the spokes to make sure the rims are straight and will stay that way. A typical wheel truing operation may require a few hundred minuscule turns with a truing key.
Gears and Brakes The brakes will be aligned with the rims, and "toed" to prevent squeaking. The mechanic will also lubricate the derailleur cables, set the cable tension and adjust positioning of derailleurs for accurate shifting, and set the limit screws on the derailleurs, to make sure the chain doesn't skip off the cogs.
