Description

The Mercury S5 Road Wheels are designed for all-around performance, featuring a 50mm rim depth that boosts aerodynamics without sacrificing versatility. The refined carbon construction yields a stiff rim with responsive steering, with a bit of added compliance for rough roads. Tubeless compatibility allows you to run slightly lower pressures for improved comfort and grip, as well as increased puncture resistance.

The S5's construction uses Mercury's Dual Carbon Layer Process, or DLP. DLP blends high and mid-moduli carbon fibers to offer the best balance between the lightweight and stiffness of the former and the fatigue-resistance and durability of the latter. DLP also involves the incorporation of basalt fibers in the brake track to reduce heat build-up and increase stopping power. This increased stopping power 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 S5s are finished off with Sapim's reliable Race spokes and Mercury's own hubs. The rear hub includes a generous six pawls for snappy engagement, and the front hub has an extra-wide 70 millimeter flange for reduced flex under hard efforts and confident stability at speed. Both hubs have an oversized axle and oversize sealed bearings that work together to ensure stiffness and long-term durability.

Unanswered Question

I noticed that this wheelset is advertised as being "tubeless" instead of "tubeless compatible" or "tubeless ready". If I decide that running tubeless tires is not worth the hassle, can I safely run clincher tires on this "tubeless" wheelset?

What a Deal!

  • Familiarity: I've put it through the wringer

I waited 8 months to write this review to see how the wheels perform. Having over 2100 miles, I can say that I love these wheels. Excellent hand built in the US. The hubs are awesome and very smooth. Coming from stock OE Mavic wheels, these are so much better. Very light and fast with Michelin pro 28c. I’m thinking of buying a set for my wife’s bike. Best carbon road wheel deal out there.

Unanswered Question

Will these wheels fit a a cannondale caad 12 105 .

55 mile initial impressions

  • Familiarity: I've used it once or twice and have initial impressions

This wheel set roll incredibly very well compared to other expensive brands. Took them on a 55 mile training ride and instantly noticed they engage very quickly, climb really well, and brakes feel responsive without the high-pitched squealing sound.

Made the leap!

    I finally made the leap into a carbon wheelset since I had an upcoming Fondo. They were perfect on my BMC.

    Made the leap!

    SRAM XDR? Can I use my 11 speed cassette?

    yeah. I have a set of the S5's with Shimano currently and emailed Mercury to inquire about XDR since I am thinking of a new Sram drivetrain.

    Fantastic!

    • Familiarity: I've put it through the wringer

    I’ve had these for 6 months and they’re great wheels. Silky smooth hubs...roll so nicely. Braking is exceptional even on big descents. Handle really good in cross winds . If you’re looking for a full carbon wheelset this is it. Well done Mercury.

    Yep, great wheelset!

    • Familiarity: I've used it several times

    I love my new S5 wheels. Strong rims and great hub set built very well. They perform nicely on the climbs and descents. Great heat resistance rims. Very impressed.

    Awesome deal and awesome wheelset.

    • Familiarity: I've used it several times

    This wheelset is great , light ,fast , and rolls pretty darn smooth. Really happy with my purchase. Wheels are true and brakes really weel like an alloy wheelset. I'm glad i got the deals.

    Nice!

    • Familiarity: I've used it several times

    I bought these for my Trek Madone and couldn’t be more pleased. Solid all around wheelset.

    Best carbon wheel deal out there.

    • Familiarity: I've put it through the wringer

    Going on 8 months and over 2100 miles so far. They ride just as good as day 1. Was able to knock some time of PR. The rims are very nice and light but the least talked about are the hubs. Super smooth with good engagement. Running Hutch 28c tires and they feel good. Love these wheels.

    not too shaby..

    • Familiarity: I've used it several times

    i currently own the old version of the M5 mercury wheelset solid performer no issues yet,comparing the two the S5 is pretty solid being it a tubeless is a plus no issues yet...

    Incredible value!

    • Familiarity: I've put it through the wringer

    Finally a sub $1000 wheelset with great braking and high heat resistance carbon. Very stable and strong plus hand built in Utah. Love them.

    Inexpensive but Fast and Stable

    • Familiarity: I've put it through the wringer

    So far 2800 miles on them. I was a little reluctant to pull the trigger on these wheels since I was concerned on how they would handle in crosswinds. I live along the coast and much of my riding is exposed to crosswinds blowing in off the ocean. I'm happy to report that they are very well behaved in the wind. In fact they seem more stable than my older 404’s. The hubs are great and very smooth. Can’t beat the price plus they look great. Well done Mercury.

    Super deal!

    • Familiarity: I've used it once or twice and have initial impressions

    Just got these wheels for my BH. My first 60 mile ride; 2700 feet of climbing with 35-40 mph wind. These are light, snappy, less prone to wind deflection, and very stable on long descents. So far so good. Also they look great with the grey decals.

    Nice!

    • Familiarity: I've put it through the wringer

    Put them on my Specialized for some race wheels. Very stiff and strong wheels. Riding with Michelin Pro 25mm tires makes for a perfect combo, especially on rides longer than 50 miles. Love these wheels.

    Love these!

    • Familiarity: I've put it through the wringer

    I’ve ridden these for over 1800 miles and the performance and riding stability have been great. Riding conti 28c on them and love it. I have a set of Zipp 454 and these are much better riding at a third of the cost. Highly highly recommend.

    Great Performance

      Never mind the price tag, these are a solid performing wheel all around. The quality is there.

      Impressive!

      • Familiarity: I've put it through the wringer

      Blew up my Enve's in the last corner of a crit and needed a quick replacement set of wheels that were light and dependable. I have a set of mercury's X1 wheels and like them, so I bought the S5's to replace my Enve's. They are incredible all around wheels for less than a thousand bucks. Two thumbs up!
