    It's easy to get caught up in the Europro kerfluffle around disc brakes and heated discussions of their place in the peloton, but one ride on that new disc-equipped steed and you'll understand why discs are the way of the future with powerful modulation that far outpaces even the best rim brakes on the market. Although you're definitely on board with discs, you're not as stoked on the stock wheels your bike arrived with and it's time to add a bit of carbon bling in the shape of Mercury Wheels' M3 Carbon Disc Road Clincher Wheelset.

    The M3's 30mm depth strikes an all-purpose balance between straight-line speed and crosswind stability while remaining light enough to satisfy our high-mountain climbing ambitions. At first glance, the 16mm internal width may sounds paltry compared to the ever-more-mammoth current rim width trends, but falls right in line with recommendations for an ideal width to house the 25 and 28mm 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 change tire type.

    • A disc-equipped carbon wheelset with all-round capabilities
    • Carbon fiber rim construction lowers weight and boosts stiffness
    • Rim depth balances aerodynamic speed and light weight for climbing
    • Durable, machined aluminum hubs roll fast and smooth
    • 4-pawl freehub responds quickly to pedal input
    • Compatible with 6-bolt disc rotors
    • Includes end caps for 12mm and 15mm front thru-axles
    • Item #MCW000Q

    Road Disc!!

    • Familiarity: I've put it through the wringer

    I just moved to a hilly area and decided to give the road disc brake a chance for the better braking performance. It is quite a bit different than my usual rim brake rig, but I like it so far.
    I wanted a real set of wheels instead of the standard crappy wheels that came with my bike, so I started my search.
    I found the Mercury M3's to be decently light and at the right price. After some research, I found out they are hand built in the US.
    Great set of wheels and am really happy with them. I decided on the shallower depth wheels instead of the racier ones since I am riding longer distances and wanted a more comfortable ride. I found them to be responsive, but not overly stiff.

    Are these tubeless compatible? Thanks

    I have them set up with a set of Maxxis Padrones with tubeless tape that is specific to road bikes since it can handle higher tire pressure. I used orange seals sealant with a set of tubeless valves. They were really easy to set up.
