The cleat bolts are very straightforward. The oval Sub-Washer (far right) is installed first, to distribute load evenly on the nylon cleat. Then the M5 washer (center) slides on the bolt, and you tighten as normal.

Mercury is currently out of production.

Yes, the highly-anticipated TriRig Mercury pedals are finally here. Head to the store to pick up a pair for yourself, or have a look in the 'Related Articles' section below for details on installation, mechanics, and all the other goods on these pedals. This gallery is a supersized set of images of the final production hardware. We actually mananged to make the final pedals LIGHTER than the prototypes, coming in at a feathery 93g for the PAIR of pedals, and just 151g complete with both cleats and all hardware. There is really nothing on the market quite like Mercury, and we definitely recommend having a look at the in-depth articles to get a sense of just why they're so special.


Back to article: TriRig Mercury: Installation and F.A.Q.


  • This is the TriRig Mercury - our take on the perfect pedal.
  • Mercury pedals are simplicity defined. Just three parts per pedal, and they look oh so good. The revised bearings are now just a simple cylinder. The lateral retention flanges have been moved to metal components for greater durability.
  • The new nylon bearing material we've selected is more durable than before, and almost looks a bit like carbon fiber. Works for me!
  • The system is held in place by an M8 End Bolt that also provides lateral cleat retention. The non-drive side bolt (left) has the stripe, and standard threads. The drive-side bolt (right) is plain, and reverse-threaded.
  • Mercury's cleats are as simple as the pedals. The one-piece nylon construction is simple to use and simple to clean. And there's just a touch of TriRig class with the TR logo embossed into each cleat body.
  • The non-drive-side pedal (right) is identified by the small stripe on the spindle.
  • And here is the money shot. Just 93g for both pedals, and no rider weight limit.
  • Just 151g for the complete system including cleats and all hardware.
  • When using the black Spacers (left) to adjust the pedal's Q-factor, you must also slide the corresponding aluminum washer (right) onto the End Bolt. For each pedal, you can choose +0mm, +3mm, +6mm, or +9mm of Q-factor adjustment.
  • Shown here is the 6mm spacer being installed on the non-drive-side pedal. The 6mm washer is on the End Bolt.
  • The cleat bolts are very straightforward. The oval Sub-Washer (far right) is installed first, to distribute load evenly on the nylon cleat. Then the M5 washer (center) slides on the bolt, and you tighten as normal.
  • Here's the cleat with just the oval Sub-Washers installed.
  • It can be confusing to talk about reverse and standard threads without a visual to help wrap your brain around it.
  • Another detail shot of the stripe which helps to help differentiate the drive-side from non-drive-side pedal.
  • The standard grey bearings come pre-installed on the Mercury pedals (left). A second set of dark brown Oversized Bearings are included with the Mercury pedals for use if your particular installation results in low cleat retention and/or unintended clip-outs.
