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.

Great Deal!

These are the best over all performing wheels I have ridden throughout the years. They beat Zipp 404, and a whole bunch of others and they are priced very good.

Loud hubs, but broken as well

True to size

I picked these up as my first carbon wheelset. I loved them right off the bat and lasted a good 9 months of riding. I went to change my chain and took the wheel off. Sure enough, the cassette just fell off. Apparently there is a support rod that holds the internal hub together that sheered off. I've never seen a hub fail like this. I've emailed support from Mercury and hopefully I'll get a replacement. Fingers crossed. Update review: Customer service has been a great help and very responsive. Sent replacement hub parts quickly.

I put a set of these S5 wheels on a Litespeed I was building and I love them. They are light weight and strong. They accelerate well and are good on the climbs. I don't think you can find a better wheels for the price. I would recommend and have recommended these to my riding buddies.

I absolutely love these wheels. Mercury nails it with the S5! Amazing ride quality! Great craftsmanship. Cuts through wind great and super light weight. I paired these with the Michelin Power 28c tires and I still can't get over how smooth the ride is. A must have for sure if you're in the market for a carbon wheel set at a great price.

Waited a little over a year to write a review. I can't believe how good these S5 wheels are! They're just straight up fast. Hubs are extremely smooth. Great aero properties, they do really well in cross winds and they are just stiff as hell. Running Conti 5000 28c tires on them and they feel good. Best purchase that I’ve made in a long time.

Just upgraded my OE stock wheels on my Colnago C59 and what a difference in the ride. They preform great on climbs and descents plus handle crosswinds good. They come with Mercury brake pads and they work well without any squeal. Tubeless setup was easy with no issues. Very impressed with these wheels.

Great Buy!

I added these to my BMC about 8 months ago, to upgrade over the standard Mavic aluminum wheels. This is my first set of carbon wheels and to be honest, I really wasn't expecting to notice a big difference. I am really impressed with how stiff, light and lively these wheels feel. It is an excellent upgrade and when you combine the budget price it a unbelievable deal. Highly recommend these wheels.

Yes do they have the brake pads?

Yes, pads, rim tape and spacer for 10 speed cassette come with the wheels.

Did they come with brake pads?

It says 'shimano HG' -- does this refer to modern shimano 11-spd cassettes? I have a 2017 Cannondale Synapse and want to make sure it's compatible with my 105 cassette/build. Thanks!

S5 goodness!

Familiarity:
I've used it several times

I needed a new set of wheels for my older Basso that was affordable. The S5’s make for a great all-around wheel set that can be used for both training and racing. Smooth rolling hubs and with the gray decals they look good.

I needed a set of carbon wheels for my older Cervelo P2 that wasn’t going to break the bank. What a great set of wheels. This wheelset roll incredibly well. Super responsive with good freehub engagement. Handles crosswinds great with good braking without the noise. True all around performance.

If you are looking for a incredible training and race wheelset that won't break your bank, are stiff, aero, and ready to go, these wheels are for you. Great job Mercury.

What size valve length do you use on the S5 rim with a tube? Thanks

Do these come with the mercury brake pads? On their website it lists them as included but no mention on this listing. Thanks

Yes, these come with brake pads.

A high quality full carbon wheelset under 1600g + sub $800 wheelset that's actually very good. I’ve had mine for over 2 years and everything is great with them. Highly recommend.

I bought these last year for my older Colnago C60 and couldn’t be more pleased with over 3k on them so far. Easy tubeless setup. Great all around wheelset.
