Pedaling Redefined

The TriRig Mercury is our take on the perfect pedal. It's ultra-light, incredibly simple, and provides the most solid pedaling platform you'll ever experience. It's a radical departure from the standard offerings on the market today, and because of that, we are offering a six-month return policy so that you can try out the pedals without fear that they won't work for you. We're so confident that you'll love them, we have no problem letting you use them for an entire racing season -- if you don't like them, send them back for a full refund.

For full installation instructions, please read the installation guide and watch the video below. For an in-depth look at what Mercury is all about, check out the features page. Here are the highlights:

  • Ultra light, at just 46.5 grams per pedal, and a complete system weight (both pedals, both cleats, and all fasteners) of 151 grams.
  • Ultra-low stack of just 10.5mm - the lowest stack on the market for 3-hole road shoes.
  • Adjustable Q-factor to fine-tune your stance width. Mercury is the only pedal on the market with this feature.
  • Incredibly simple design, just three parts per pedal (titanium Spindle, nylon Bearing, aluminum End Bolt). Mercury is an easy-to-service, virtually zero-maintenance product.
  • Replacement cleats and bearings will be available in the coming months right here on this page, but are currently not available for purchase.

Six-Month Return Policy

We want everyone to be able to try out Mercury with confidence. To that end, we give you a full six months to use the pedals as much as you like, and if you don't totally love them, you can send them back for a full refund, no questions asked. Here are the details of the Mercury return policy.

  • You have 180 days from the date of purchase to request a return on Mercury. We will not extend this time frame for any reason.
  • The pedals need not be in pristine condition upon return. We understand you're going to use them, and that the plastic components will likely suffer some wear. The cleats, bearings, and spacers may be in any condition upon return.
  • The aluminum M8 bolts must be in like new condition. If not, your return will still be accepted, but we may assess a $20 for each broken bolt in order to refurbish the pedal with a new one.
  • The titanium spindle bodies MUST be in like-new condition in order for us to accept a return. A pedal CANNOT be returned if there is damage to the internal or external threads, or if either spindle has been cracked, broken, bent, or otherwise damaged.
  • If your return is accepted, you will be refunded the original purchase price you paid for the Mercury pedals, excluding shipping. You are also responsible for the return shipping back to TriRig, as well as any PayPal fees associated with the refund.
  • This return policy supersedes our standard return policy, and applies ONLY to Mercury pedals. If you order any other items from TriRig, they are subject to the standard return policy.
  • Return policy does NOT apply to any items marked for CLEARANCE. Clearance purchases may not be returned.
