The highly-anticipated TriRig Mercury pedals are finally here. Head to the Store to pick up a pair for yourself. This article contains installation information, as well as frequently-asked questions about Mercury. We have made some significant changes since the first production batch, and the new Mercury pedals are better than ever. There's a lot going on with the new hardware. If you aren't familiar with Mercury, we definitely recommend having a look at the in-depth introduction articles to get a sense of just why they're so special.
For those of you who are already familiar with what Mercury is all about, here is what has been updated for production going forward:
Mercury: What's New?
- Solid core
- No rider weight limit
- The first change we have made to Mercury is to convert the hollow-core spindle into a solid piece of titanium. The additional material adds just 9 grams of weight to each spindle, but makes a world of difference in terms of strength and durability. And most importantly, it allows us to remove the Mercury rider weight limit! That's right, now anyone can get on board with the coolest pedals on the market.
- Streamlined construction
- Higher-quality nylon
- Perhaps the most noticeable change in terms of design is the new bearing. The original Mercury bearings included the flanges that function to prevent lateral cleat movement. But they were subject to damage if the user clipped in incorrectly. So, the flanges were moved off the bearing and onto metal features, which means the bearing is now just a simple cylinder. The elegance of this solution had me wondering why we didn't just do this in the first place.
- We have upgraded the nylon from the original version of the Mercury. The new PTFE material is stronger, exhibis lower friction, and has a beautiful aesthetic finish.
- Also, every Mercury assembly now includes two sets of bearings. The standard bearings come pre-installed on the pedals, and a second oversized set of bearings ("OS bearings") is included in the box. These may be necessary in cases of poor cleat retention. Please refer to the installation page for more information on the OS bearings.
- Replaces Bearing Flange
- Standard and reverse threading
- As mentioned above, the first-gen bearing flanges were moved off the bearing. They've been placed instead onto existing features of the Mercury design. The outboard flange is now part of the end bolt which holds the whole pedal together. This ensures that no matter how poorly a user clips into the pedals, everything will remain undamaged.
- Moreover, those end bolts now have individual thread directions. The drive-side end bolt is reverse-threaded (left-hand threaded). The non-drive-side end bolt uses standard (right-hand) threads. This ensures that even if the pedal end bolt is under-torqued, no amount of improper pedal technique could possibly cause the pedal to come apart during a ride.
- Same great pedals
- The rest of Mercury's great features remain the same. The ultra-low stack height, Q-factor adjustment, and minimal cleat design are all unchanged. The complete system (pedals, cleats, and ALL fastening hardware) comes in at a scant 151g. The pedals alone are 93g. And yeah, that's 93g for the PAIR of them.
