S5 Disc Wheelset
The Mercury S5 Disc Wheels strike a fine balance between a lightweight climbing wheel and an aerodynamic race wheel, featuring a slightly shallower 50mm rim depth that's just as happy pedaling up a mountain pass as it is sprinting along flat tarmac and gently sloping roads.
- 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
- Item #MCW1WUK

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.

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
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.

If I may ask, what size Gravel Kings SKs did you have on?

Great all around carbon wheelset!
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.

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.

Full carbon wheelset!
I’m a heavier rider at 215 pounds and these have held up to some hard riding. Running Michelin 28c tires on them and the ride good. So far just over a 1000 miles on them and no issues. Great, quality all around wheelset.

Smooth, Fast and a Great price.
I’ve had these wheels for 6 months with over 1400 miles with no problems. . They are lightweight, extremely stable, and aerodynamic.. They cut through the air nicely, and crosswinds do not have much effect. Very smooth hubs. Highly recommend.

Nice job Mercury!
The S5's are a perfect depth for me. I am a lighter rider, so am highly susceptible to any sort of winds and ride mostly on or near the Monterey coast where it is always windy.

For the first ride, I threw them in my "go to" bike (Tarmac) and rode my regular Tuesday night 30 mile group ride. I immediately noticed a difference in cornering and out of the saddle sprints. They track nicely and didn't notice any lateral flex. Second ride would be a century where at the end of the ride I didn't feel beat up and felt better than I usually do after a century. They handled nicely even with some severe cross winds. My third ride will be over the labor day weekend where I will be riding 3 days in a row for 200 miles. The route has over 5K feet of climbing, so am anxious to see how they perform in the hills.

great wheels. smooth bearings and I like the gun metal gray hubs.

I have my the Peter Sagan Gran Fondo coming up and wanted to roll a faster set of wheels. Was a snap to place my new DA cassette body on and shifts perfectly. The wheels are light and feel like a nice pair of wheels. You can tell the quality is there.

Best $$ spent
You always hear about wheels making the biggest difference on your bike, but never thought I was good enough. Raced in my third Tri ever and actually beat the guy I have been gunning for in the previous two races. He usually beats me in the overall time and bike leg. Not this time! I beat him by over 2 minutes on the bike alone and by 3 minutes overall!! I also broke my previous average speed by 1.6 mph.

I just upgraded my stock wheels on my Ridley to these full carbon wheels. I can’t believe these wheels are sub $1000. Great all around wheelset that actually light weight. Nice rolling hubs.

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.
December 19, 2019
Suitable for CX and Gravel riding?
December 19, 2019
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.

What’s the widest tire I could put in these rims?

Are these wheels Competitive Cyclists house brand?

I was wondering, does anyone know if these are adaptable to QR axles? I have a Cannondale caad12. If so what parts would I need? thanks!
