The hex pedal wrench for modern road clipless

Modern road clipless pedals trade the 15 mm wrench-flats for a 6 mm hex socket at the inboard end of the spindle. The redesign saves weight on the spindle, but it leaves the mechanic with two awkward problems: the 6 mm hex sits behind the crank arm where leverage is limited, and the install torque (35–40 Nm) is the same as on a flats-and-wrench pedal that has twice the lever arm available.

The Speed Pedal Wrench is the answer. The swivel handle locks at 90 degrees for the install and removal extremes where leverage is everything, and locks at 0 degrees (straight through the handle and shaft) for the rapid-spinning portion where the pedal threads in or out across most of its travel under no significant load.

What “swivel handle” actually does in the workshop

A standard hex wrench is one geometry: long arm one way, short arm the other. On a 6 mm hex pedal behind a crank arm, the long arm collides with the chainstay and the short arm gives up too much leverage. The wrench-slip moments that round the hex socket happen in that bind.

The swivel handle's lockable joint lets the handle rotate to whatever angle clears the frame, then locks firmly so the mechanic applies install-torque without flex at the joint. Leverage of a long wrench in the swing arc of a short one.

Compatibility

Fits any pedal with a 6 mm hex socket at the inboard end of the spindle. This is the current-generation standard on most premium road clipless designs. Older traditional clipless and most MTB clipless designs use 8 mm hex; see the Speed Pedal Wrench 8mm for those. Pedals with 15 mm wrench flats are best served by the Pro Pedal Wrench or home Pedal Wrench.

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 “premium flex chrome-vanadium steel” designation on this wrench is Unior's workshop-grade alloy for hex-engagement tools, hardened and tempered to the ISO 3315 dimensional and durability spec. The “flex plus” temper is what lets the swivel-handle joint take repeat install cycles without fatiguing at the lock.

Pro tip from our mechanics

A 6 mm hex pedal that will not loosen is almost always a corroded thread, not a too-tight hex socket. Switching to a longer wrench rounds the socket; the right move is anti-seize before install and patience on removal.
