The typical bicycle wheel is composed of a rim suspended with tensioned spokes around a center hub. Each spoke pulls on a section of rim. Spokes coming from the right side hub flange pull the rim to the right. Spokes coming from the left side hub flange pull the rim to the left. Spokes attached at the rim are then offset in a left-right-left-right pattern to counter the pull of the other side. Having all the spokes tight with fairly even tension makes the wheel true and strong. Changes to spoke tension will pull on the rim and affect its true. This process is called “truing”. Truing is occasionally needed to keep the rim running straight as it spins between the brake pads.
Pricing starts at $25 for basic truing and can vary depending on size, type and issues. Highly recommend removing all gears, rotor, tire, tube and rim strip to keep cost down. This leaves the wheel ready to be worked on. If items have to be removed to true the wheel additional labor will be charged.
Tubeless wheels will incur an additional $30 labor and Sealant charge if tire is still on the wheel.
