Description

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 for a simple tubeless setup
  • Disc brake only, 12mm thru-axle hubs

Fast Wheels

Familiarity:
I've put it through the wringer

These S5’s disc wheels are just perfect. They are light as a feather and very fast. Hubs are buttery smooth. I can't explain how perfect these are. You will not find something with this quality for this price. Love them!

Logged a few hundred miles on these so far and they’ve been awesome. For the price, I honestly don’t think you can do any better than this wheel set. You can definitely feel any cross wind with these, but that’s probably the same with all these style rims. They seem very durable and I’m sure I’ll have them for a long time.

I absolutely love these wheels! Mercury nails it with the S5’s. Great ride quality. Great craftsmanship. Just overall great product. Cuts through wind great and super light weight. Highly recommend.

What's the max psi for these wheels? Also, are they compatible with schwalbe pro tubeless tires, 28mm? I've been unsuccessful setting up so far.

I'm tellin you the wheels are an absolute must have, forget about spending thousands on other wheels. I am running 28c Gatorskins and they’re great. I have thousands of miles on them and NEVER trued them. I know thats hard to believe but BELIEVE IT. Plus they look great on my Litespeed.

Fast wheels, slowest tires ever....

Jared do you know what’s slower than gatorskins? Punctures.

Hello...can this wheel set be use for pinarello gan disk 2108?

Hi Augustus, You can 100% run these on your Pinarello Gan Disk. Please be sure to pick the correct freehub body for the wheelset. In this case, it will be the Shimano/Sram HG driver body.

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.

Do you run tubeless with your tire and wheel set-up?

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 put it through the wringer

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.

Excellent wheels

Familiarity:
I've used it several times

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.

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

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!

I was planning on these for my 2020 Roubaix Sport

James and Curtis, Got this for a 2020 Specialized Roubaix Sport. Stock DT Swiss R470 are great, but these S5's are something else. Great on the flats, but I feel the difference mostly on the climbing. Before the S5's, I've tried Shimano's carbon alloy wheelsets as well. They weigh similar to the S5, but the S5 accelerates much faster. Go for it my Roubaix bros, it makes our "tame" Roubaix's a lot wilder.
