Mercury WheelsM5 Carbon Disc Road Wheelset - Clincher

The future is here.

While the UCI sorts out its rules around discs, the mortals among us can take full advantage of the powerful modulation and confident stopping that accompany disc-equipped road bikes. Even better, wheelsets like Mercury Wheels' M5 Carbon Disc Road Clincher Wheelset allow you to harness all those braking advantages while also gaining a big dose of aerodynamic speed.

The M5's 55mm depth is purpose built for forward speed, commonly touted as the ideal profile to serve as an all-around wheelset for those of us who live in all but the most mountainous of terrain. You'll sacrifice a bit of climbing prowess for that depth, but the M5 makes up for it in spades when you hit the flats and get your speed back.

The rim width is also worth a mention, because at first glance, the 16mm internal width is narrow compared to the current trends racing towards ever wider rims. However, it falls right in line with recommendations for an ideal platform to house the 25mm tires so commonly found within the peloton. That 16mm rim is also compatible with 23mm tires, allowing the traditionalists among us to make the jump to disc without also having to also adjust to a new tire type.

  • Familiarity: I've put it through the wringer

These wheels have changed my ride drastically. Super fast and super responsive.
Being a on bike that isn't as aerodynamic as others, I didn't think that deep dish wheels would really improve much but I was wrong.
Build quality has been astounding. Haven't needed a true with over two tough seasons on them.

These are my first set of carbon disc wheelset. These wheels are fast, sturdy and spin forever. These wheels were a great way to upgrade my bike at a reasonable cost. Well done Mercury.

Excellent wheelset!

  • Familiarity: I've used it several times

I've had these wheels for about 3 months and have had no issues whatsoever. They handle great and are very well built.

Are the decals removable and do they come with stealth/gray decals?

Can we use 28mm tires with these wheels?

mine came with removable white decals attached and a set of gray stealth decals.

Are QR endcaps included in this purchase?

Hey Alex, we checked on your question. The packaged Mercury M5 wheelset for sale on our site only comes with the Thru-axle adapters. Mercury does have the endcaps on their site for $25 (as of 7/6/17).
