Mercury WheelsS5 Disc Wheelset - Tubeless
Item # MCW1WUK
The Mercury S5 Disc Wheels strike a fine balance between a lightweight climbing wheel and a purely aero wheel, featuring a slightly shallower 50mm rim depth that's just as happy grinding up a mountain pass as it is sprinting along flat tarmac and gently sloping roads.
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. The result is a rim that remains stiff under hard sprinting efforts, yet offers a greater degree of compliance over rough roads.
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.
- Carbon fiber road wheels well-suited to all-around riding
- Carbon layup finds the ideal balance of stiffness and compliance
- 50mm rim depth offers aero gains without giving up versatility
- Reliable Mercury sealed bearing hub with snappy engagement
- Tubeless compatibility for increased grip and comfort
- Hand-built in Utah by Mercury's expert wheel builders
- Includes rim strips, valve extenders, cassette spacer
- Disc brake only, 12mm thru-axle hubs

Best value for your money, hands down. These wheels are light and strong. I've put almost 3000 miles on them and the Continental GP 5000 that I bought along with them to complete my light and tough setup. Highly recommend.

I just upgraded my DT wheels on my Canyon to these wheels. Nice smooth rolling hubs. Wheels are great on flats and they climb well. Very happy with this purchase.

I've been running these tubeless with 28s on my Fenix and love them. They are fast and light on the road, easily keep pace on fast group rides but still stout enough to tackle fire roads and gravel with confidence. Very happy so far.

Best Carbon wheelset deal out there!
- Familiarity:

I've had these wheels for about 6 months, still absolutely no issues whatsoever. Drag from crosswind is minimal. Super responsive, light, and fast. I can tell a HUGE difference from the Hed wheels I had previously. Great deal plus they look good.

Fantastic wheel set. Stiff, quick to speed. I prefer Vittoria Corsa tires and the graphene 2.0 were a very tight fit. If you get the disc version you will need the XT outside notched lock ring. After several rides I can think of nothing bad to say about these.

Big difference
- Familiarity:
- I've used it once or twice and have initial impressions
First set of carbon wheels; first set of wheels deeper than 25mm. Rode up Emigration Canyon today, 11.5 miles from my house to Little Mountain Pass, and rode 3:20 faster than two weeks ago on stock wheels/tires (same time of day; same wind conditions). 2019 Specialized Roubaix. I have these set up as tubeless with 28mm Continental GP5000TL's. At 65 PSI, the ride is so much smoother than stock 28mm Specialized tires at 85 psi. I couldn't be happier with this purchase. This takes "value" carbon wheels to a whole other level. Hundreds less than other respected brander wheels like Hunt.

Hey Matt. No problem mounting the Conti tires. The S5’s are sweet wheels with no issues so far. Definitely recommend.

Hi Jason. I might be getting a 2020 Roubaix Comp that comes stock with DT R470 Disc wheels with 28c tires. How much lighter/better are these Mercury WheelsS5 Disc wheels compared to the stock wheels? thanks!

My first true set of carbon tubeless wheels and they have not disappointed. My Cervelo R3 looks like a machine ready to handle whatever the road lays in its path. Adding Conti GP 5000’s to the mix makes it even better. If in the market for a decently priced wheelset - look no further! Mercury S5 is it!

I bought these wheels for my Trek Mondane. For reference, I am 6’1” 195. The rims felt really solid when sprinting and held their own. This is a solid overall wheel that does everything well from climbing to aerodynamics. I highly recommend these wheels.

What are the recommended tire widths for this rim for a tubeless set up? Please comment on tire brands as it seems different tires brands can have different measured widths at the same stated widths.

I bought these about 10 months ago and have put over 1800 miles on these with no issues. Have been running 25c tires on them and they've been great. I haven't had to true them at all. Super smooth hubset.

Just upgraded my Cervelo S-Series to these wheels and I’m loving them. Increase my pr time on my daily route. Lightweight and sturdy. They handle cross winds very well. Great deal on these.

Go to Gravel wheels
- Familiarity:
- I've put it through the wringer
After reading the other reviews I decided to grab a set for my Moots Route 45. The subtle graphics "caught my eye" as I am a no frills type of guy. The performance is what I am most impressed with. They are handbuilt in the US, smooth bearings even after I have ridden it in some slop and have a great ride feel about them. Weighing 195 pounds I tend to flex most wheels, but the S5's seem to have the ride feel and performance balance figured out. Tubeless set up was easy with my Gravel King SK's. All in all, I am pleased with the wheels and would buy them again.

With nearly 6k miles, I am very happy with my S5’s. I’m 200 pounds, along with road miles I ride some loose gravel, and they hold up well. The wheels remain true and show no signs of problems. The hubs roll smooth. At the sale price, I might get a set for my girlfriends bike. Very impressive for a great price. Nothing beats hand built wheels.

Suitable for CX and Gravel riding?

Hey Mike, Due to the internal width being quite narrow you would be quite limited in tire sizes for CX/Gravel riding. Let's chat on what might be better options for you though!

I am riding mine on nothing but gravel. Tubeless set up was a breeze.

I waited to write this review to see how the wheels perform. Having over 2k miles, I can say that I love these wheels! Excellent all around wheelset! Plus they’re hand made in UT. The hubs are awesome and roll forever. Running Michelin Pro 28c tires on them and they feel great.

I’ve been looking for a new set of carbon wheels for my Ridley that wasn't going to break the bank and I found these. For a deep depth rim, it handled wind gusts well and maintained speed with the aerodynamic profile. Paired with Conti 5000 28's, they felt great handling rough roads and cornered great, and a good all around wheel. This is a solid wheelset that does everything well from climbing to aerodynamics. Two thumbs up.

Very happy with this carbon wheelset as an upgrade to my factory wheels. These S5’s are very light and extremely durable. Full season on them with no issues. Straight as the first day I pulled them out of the box. Highly recommend.

Jason C.- Are you still as enthusiastic as you were when you wrote this review? I have a Specialized Roubaix Comp that needs a wheel upgrade. I was leaning towards the Roval CL 50 but that is twice as expensive as the Mercury S5. No problems mounting the Conti GP5000? Any guidance is much appreciated- Matt
