The god of stealing races.

It's appropriate that Mercury Wheels' name and logo reference a Roman god who is the patron of, among other things, travelers and thieves. Atop Mercury's M5 Clincher Wheelset, Eric Marcotte journeyed from his day job in Arizona to Chattanooga, Tennessee to nab the 2014 US national championship ahead of the pros of the European peloton. It's the ultimate race wheel for the working cyclist.

If you're in the market for deep dish carbon rims, then you've probably already made the assumption that the number in the M5's name denotes a depth of 55mm. The rim's width is left out, though, and rim width is a big deal these days. The M5 is a solid 23.5mm wide, which means you can run lower PSI for a more comfortable ride that corners with unparalleled confidence. Wider rims also have some counter-intuitive effects when compared to those standard 19mm rims: they actually decrease rolling resistance and increase aerodynamics.

The M5s' construction uses Mercury's Dual Carbon Layer Process, or DLP. DLP blends high- and mid-moduli carbon fibers to tease out the best balance between the lightweight and stiffness of the former and the fatigue-resistance and durability of the latter. DLP has also recently been updated with a newly engineered brake track material, improving stopping power over the previous, basalt-infused design. This increased confidence goes a long way toward addressing the poor braking that is one of the most common critiques of carbon wheels.

The aerodynamic benefits of a deep dish rim are further complemented by Mercury's Seamless Transition Technology (STT), which integrates the brake strip with the rest of the rim in order to eliminate any obstructions to wind flow and reduce drag-causing turbulence. The result of this construction is a wheel that balances the above qualities with considerations of weight for what Mercury claims is its "most popular wheel by far."

The M5s are finished off with Sapim's indefatigable CX-Ray spokes and Mercury's own hubs. The rear hub includes a generous six pawls for an engagement that's as close to immediate as anything we've seen on the market today, and the front hub has an extra-wide 72mm flange for reduced flex under hard efforts and confident stability at speed. Both hubs have a 15mm axle that reduces to accommodate a traditional quick release and two and four oversized bearings in the front and back, respectively.

The Mercury M5 Clincher Wheelset comes with a Shimano/SRAM 11-speed compatible freehub body and includes skewers, valve extenders, brake pads, and rim strips.

Are these tubeless?

Excellent Value, Great In Cross Winds!

  • Familiarity: I've put it through the wringer

Coming from only using stock wheels on my Trek, these are an incredible upgrade. The aerodynamic advantages are really noticeable, the wheels are so stiff they encourage you to really put power through the pedals, and the value is unbeatable. Very well built wheelset.

Outstanding full carbon wheelset!

  • Familiarity: I've put it through the wringer

Couldn't be any happier. Almost as light as wheels twice the cost. Great on the flats and easy climbing. Staying strong after almost 3 yrs now. No issues at all. Looks and feels as good as new. Highly recommend!


  • Familiarity: I've put it through the wringer

I would consider myself to be a slight nerd and do my share of research on any product where I spend over $100.
I read a ton of good reviews, saw they were ridden in the pro peloton and the price was right, so I bought a set. They are a great wheel set and were actually built up in the US.

Solid wheel

  • Familiarity: I've used it several times

These are my first carbon wheels and I was nervous to make the jump mostly due to fears of worse brake power. Those fears are squashed for me. These stop as good if not better than my aluminum brake track wheels. I didn’t have any issues with brake squeal and I’m a terrible mechanic.
The wheels feel very smooth when rolling. Feel stiff when climbing. And feel strong to support me at 185lbs
The stickers were not glasses in so I removed and now the wheel/bike combo is black AF.
Overall, I’m happy I made the jump

Unanswered Question

are these rims tubeless or tubeless ready??? they are listed on a google search in the tubeless category, but I doubt it, based on specs. thanx

Great carbon wheelset!

  • Familiarity: I've put it through the wringer

I picked these M5's up 14 months ago and have put over 2800 miles without any issues. I have ridden on some very rough roads and they stay stiff and true. A huge fan of Mercury wheels.

Great Quality And Value!

  • Familiarity: I've put it through the wringer

I decided to upgrade my stock wheel on my Specialized with these and couldn't be more pleased. They're light, stiff and fast too! They roll extremely well and the hubs are great. Great quality wheelset plus they're handmade in the USA.

These Mercury M5's are a steal!

  • Familiarity: I've put it through the wringer

I have 3k miles on these wheels with ZERO issue, amazing on the flats and climbs as fast as anyone else. Quick wheels at an unbeatable price.

What color is the decal on this wheel set? The last stock picture shows gray/black Mercury decal.



Those decals come in the box if you want to switch

Revision. The gray decals no longer come with the wheels.

I have Campagnolo Record 11 model 2017, could I use this wheels? Is there any hub that can I use for this wheels?

Yes. Search item#MCW0008. we don't have the Freehub or wheels in stock but there are options for your setup

Would these work well for Tri s? Could I run 25 mm tires on these rims on a 2017 Cervelo P2?

Fantastic Wheelset!

  • Familiarity: I've put it through the wringer

I absolutely love my Mercury's, I've put over 4,000 miles trouble free miles on them in the past year. Ride great in the flats, climb well, have excellent cornering and do great in the wind. They are a fantastic all around wheel set, I love them so much I order a pair for my wife's bike.

Expectations surpassed!

  • Familiarity: I've used it several times

Great wheels at a bargain price. I would compare this wheel set to be equal to my previous roval cl40’™s and Zipp 404’™s. The Mercury’s setup perfect with conti gp4000 25’™s. I setup brake pads as mercury suggests and braking has been quiet and surprisingly powerful. The wheelset build quality is extremely nice. I wanted a quality aero set for riding my local routes with short punchy climbs and rolling hills, and these are plenty light to roll up and over my favorite routes.

Expectations surpassed!

Fast Wheels!

  • Familiarity: I've put it through the wringer

I own a couple of sets of carbons wheels from other brands and wanted something new for my Trek. So I pulled the trigger on these Mercury M5's and couldn't be happier.

Unanswered Question

Does anyone know what the internal rim width is?

Great wheelset!

  • Familiarity: I've put it through the wringer

Best carbon wheelset I've ever had. I've had them for over one year and have never had issues. They roll super fast and are very lightweight, extremely great wheelset for the price. I recommended these wheels to anyone who wants the go fast. All of my race times improved dramatically. Also they're great looking.

bang for buck

  • Familiarity: I've put it through the wringer

I’ve raced these in pro 1/2 events without any issues. I’ve been on Zipp, Vision, HED wheels. These are light enough and plenty stiff enough to handle constant accelerating in crits.

Great Performance wheelset

  • Familiarity: I've put it through the wringer

I purchased a set of the M5 wheels for my wife and myself. We ride in CA where the roads are not in the best shape and I love the feel of them. The wheels look great, are light weight, and made with excellent quality. These wheels come with excellent hubs with good engagement. Buy yourself a set, you will not regret it.
