    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.


    • 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.

    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.


    • 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.


    • 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!


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

    I had been searching for a set of carbon wheels for a bit. Narrowed down my search and did a lot of research. The Mercury wheels won...hands down. They replaced the original equipment on my Argon18. Weight loss is awesome! Loving them so far!


    Wheely Good Wheels

    • Familiarity: I've put it through the wringer

    Inital Review with roughly 850 miles put on the wheelset, rode tubeless setup.

    - Great looking wheelset, made in the USA.
    - Aero AF - you can feel the difference especially when riding flats & descents, while feeling lightweight & stiff when climbing. True All-around performance.
    - great hub engagement, snappy, loud (though not as loud as I9).
    - braking performance is phenomenal; quiet, extremely effective braking, never burned the brake track on steep & windy mountain descents.
    - As mentioned before: PR's be damned, these are fast as hell.
    - Tubeless performance was great, haven't had a single puncture or de-beading occur.

    Love my S5’s!

    • Familiarity: I've put it through the wringer

    These are fabulous wheels. The S5’s make for a great all-around wheel set that can be used for both training and racing. The Mercury hubs engage quickly, are very smooth and roll forever. One of the more remarkable things about this wheelset is how well they handle the crosswinds. Well done Mercury.

    It is possible to remove the decals?

    Hey Miguel,

    The Mercury print is not removable, it is either stamped or etched in to the rim itself. If you have any further questions, feel free to reach out to me directly at!
