Description

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.

  • Steal a march on the competition with carbon race wheels
  • Blend of carbon moduli to balance stiffness and strength
  • Brake tracks incorporate basalt fibers for better stopping
  • Integrated brake track reduces drag-inducing transitional ridges
  • Wide rims straighten allow lower PSI for smoother, faster ride
  • CX Ray Spokes and wide flanges for stiffer overall system
  • Mercury Wheels proves you don't need to spend a fortune to race on carbon

Great Wheels

    Great wheels ( sale price better ) Wheels perform incredible smooth and responsive. Were I saw the difference was against the wind; will save you some watts and easy to maintain high speeds. Great wheels in over-all.

    Great Wheels

    Fantastic wheelset!

    • Familiarity: I've put it through the wringer

    After a season, I’m very pleased and impressed with these wheels. Ride quality, cornering, braking are great. These wheels were a great way to upgrade my ride at a very reasonable price.

    To the Point

    • Familiarity: I've put it through the wringer

    I am on a budget so I had to buy a set of race wheels for crits, road races and TT's.... these worked perfectly all season. They are fast and stiff.
    Durability is an added bonus since I am now training on them as well.

    Love my M5’s!!!

    • Familiarity: I've put it through the wringer

    Three years and counting on my M5’s with no issues at all. The wheels are really smooth rolling. They’re stiff when climbing. The build quality is unmatched as they are hand built in UT. I’m running 25c Conti’s gp on them which feels good. Unbelievable deal for the money.

    Carbon wheelset Deal!!!

    • Familiarity: I've used it several times

    I got a set of Mercury M5 wheels about 6 weeks ago, I've put about 500 miles on them. My initial thoughts are that these wheels are incredible. They're light, stiff and fast. Great hubs that are very smooth. Comfortable ride with good braking and handles well in crosswinds. Super happy so far.

    Unmatched quality!!!

    • Familiarity: I've put it through the wringer

    Best carbon wheelset I’ve ever owned. Great on the flats and easy climbing. Staying strong after almost 2 yrs now. Looks and feels as good as new. Highly recommend!

    5 star wheelset!!!

    • Familiarity: I've put it through the wringer

    M5s are great set of wheels that are incredibly versatile. I use them for spring/ summer training and racing and they have held up extremely well. Relatively light, stiff and fast too! Probably the most underrated components are the hubs. Very well built wheels. Overall, are a great value!

    Best Carbon wheelset out there!

    • Familiarity: I've put it through the wringer

    Great ride today in 25+ mph winds. The stiffness is certainly there but you do not miss out on ride quality. They are easily as good as wheels costing 1.5k more. Very impressed with the overall quality.

    Would like a subdued look, are the decals removable or under a clearcoat?

    Hey Trey,



    Teammate of mine has these wheels and mentioned that the decals may be peeled off. Unsure if that has been updated but I am fairly sure it ought to be the same. Cheers!

    Amazing Value

    • Familiarity: I've put it through the wringer

    Wheels have been excellent. A lot of these reviews have rang true, although I have not had any issues with the brake pads and they've lasted a year now.

    2 years and counting- Review

    • Familiarity: I've put it through the wringer

    This review is after 2 years of riding and still going strong and also feel that people need to write reviews after long periods of usage (6’1, 175-180 lbs). I used these wheels as my upgrade into the carbon clincher world and was budgeted to $1K. I knew these wheels had brake pad issues going in so when I got them I immediately used a credit card to toe them so this was not a shock to me. The pads that came with the wheels were discarded after two months and Mercury kindly hooked me up with the recent version which then lasted me over 9/10 months. These are not to be billed as a climbing clincher wheel but for a budget carbon wheel they can climb (multiple 100+ mile races with 12k feet of climbing). Get them above 21mph and they are crazy fast. Stiff enough to handle 55mph+ turns of a technical descent and you always find yourself saving energy because of how well they hold speed. I just recently replaced the bearings in the hub but this is a cheap fix and could be a number of issues. I would recommend to replace the skewers (note: changed after 1.5 yrs to shimano ultegras because I found the wheel to be off in the frame over time and needed to be dished-solved issue). I’m giving 4 stars because there are better wheels out there and would like to remove decals but in the $1K market these are a steal. I would do it again with no apprehension. Great all around wheel that can climb, race and train. I’ve also found the folks at Mercury to be awesome when I have reached out over different questions or pad issues.

    Bang for the buck! (Decals removable)

    • Familiarity: I've put it through the wringer

    Great set of wheels. As others have mentioned, for the price, they are hard to beat. Then with a bonus free set of Michelin Power Tires and tubes, plus coupon and discounted overnight shipping... fuugghetttaboutit! Happy with the purchase and I'm slicing through my PRs like a hot knife through butter.

    For those that want to customize... I purchased different color decals directly from Mercury but after removing the white that they come with (VERY easy to remove, no adhesive residue), I loved the all black look and have left them like that.

    FYI: If you get the free Michelin Tire and tubes that come with the package, know that the tubes they send only have a 52mm valve and obviously won't work with a wheelset that is 55mm deep. You'll either need to purchase an extender or another set of tubes to use. Don't be like the guy (me) who had these tubes with a valve that was too short and then got a flat on the road and was stuck because it didn't fit.

    UPDATE: Joe from Competitive Cyclist called me after reading my review and send me a new set of 80mm valve tubes to replace the ones they originally sent me that didn't fit. Appreciate the customer service. Going out of their way like that is why I keep coming back.

    Bang for the buck! (Decals removable)

    Money Well Spent

    • Familiarity: I've put it through the wringer

    Prior to purchasing my M5's, I read numerous reviews on them and the competitors. This wheelset is consistent with the cycling reviews. A nice climber and all around good performer. At over 1600 miles so far, I highly recommend.

    What a deal!!!

    • Familiarity: I've put it through the wringer

    I absolutely love my M5's. I've put over 3700 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. Plus hand built in the USA.

    Love them!

    • Familiarity: I've used it several times

    Very light and stylish. Just upgraded to these over 4 weeks ago and I am happy. I've put about 550 miles on them so far. My initial thoughts are that these wheels are absolutely incredible. 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. Great job mercury.

    Great deal!

    • Familiarity: I've put it through the wringer

    My first set of carbon wheels for my Giant. I've had my M5's since early spring and couldn't be happier with the quality and ride. Running 28mm conti's on them which makes a good combo. They're light, stiff and fast.

    Bad bearings

    • Familiarity: I've used it several times

    I've put on less than 300 miles on this wheel set and am already replacing the bearings for the front hub. Not a big expense but certainly disappointing after spending a pretty penny on the set. Stickers were also lifting off when they first arrived but pressed them down and no issues since. Otherwise, they look sharp on the Willier and are light for deep dish.

    Are these tubeless?

    Documentation in box says they are tubeless ready. You'll need to get the appropriate tubeless liner and valves.

    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.
