The right-hand pedal thread on a crank arm fails in two common ways. The customer cross-threads the pedal at first install, cutting new (wrong) angle threads through the existing pattern. Or years of road dirt and corrosion in the thread eventually destroy the engagement surface. Either way, chasing the existing thread won't recover it. The Right Pedal Reaming Tap 1695.1AR is the tool that does.

The 1695.1AR cuts the failed right-hand thread away, enlarges the hole to a precise oversize diameter, and cuts a new thread pattern sized for the Right Pedal Thread Insert 1695.3A. "Right" matters; the right pedal threads in the standard clockwise direction, and the tap geometry is sized to match.

The reaming workflow

Pair the 1695.1AR with the Handle for Pedal Taps 1695/4BI for leverage and alignment. The handle's magnetic collet holds the tap square to the crank face during the cut, which matters because the first turn establishes the new thread's angle relative to the pedal axis. An off-axis first turn means an off-axis thread, which means a pedal that threads in but doesn't seat square against the crank.

The reaming section of the tool removes the failed thread material. The trailing thread-cutting section cuts the new thread profile. The result is a precision-sized, freshly cut hole ready for the thread insert. Press the Right Pedal Thread Insert in with thread locker, let it cure, and the crank takes a standard pedal again.

Crank Saver Kit context

The 1695.1AR is one of four components of the full pedal-thread rescue system. The others: the 1695.1AL left reaming tap, the handle, and the thread inserts. The complete kit (Crank Saver) ships as a single package; the individual parts are useful for a shop that's lost one component or stocks specific sizes.

When to choose a reaming tap vs. a chase tap

Chase the thread (with the Pedal Tap Set 1695.1) when the existing thread is intact but dirty, slightly corroded, or paint-blocked. Ream the thread (with the 1695.1AR) when the existing thread is stripped, cross-cut, or torn out and won't hold a pedal under load. The distinction matters: use the chase tap on a thread that needs reaming, and the chase won't fix it. Use the reaming tap on a thread that just needs chasing, and you're cutting good metal away unnecessarily.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The 1695 system is a Unior-specific design; the reaming-and-thread-insert pairing was developed for the cycling repair trade, not adapted from a general-machinery thread-repair kit. The threads on the insert match the cut profile of the reaming tap; substituting a Heli-Coil-style generic insert won't work because the thread profile doesn't fit.

Pro tip from our mechanics

The mechanic-economics on pedal-thread rescue are simple. A crank-arm replacement is $80–$300 depending on the build. The Crank Saver service is the cost of two tap turns plus an insert. The shop that does the rescue keeps the customer's bike running for a fraction of the replacement cost.
