TM-1 Service & Repair

Over time, especially with the repetitive use experienced in a shop, the spring on the TM-1 Tension Meter can come out of adjustment or wear out completely, causing the TM-1 to come out of calibration and no longer read spoke tensions correctly. The spring wearing out is considered wear and tear not covered by Park Tool's warranty, but Park Tool does offer service and repair for the TM-1.

Park Tool will replace the spring on a TM-1 and calibrate for a typical fee of $10.00 (sender is responsible for postage fees both ways).

If the TM-1 requires service above and beyond spring replacement and calibration, a Park Tool representative will call with an estimate before any repairs are performed.
