Since 2013 we've led the way in gravel and all-road bikes. The Z-Zero XD is the ultimate bike for all-day adventure.

Each one is made to order, by hand by the most experienced carbon team in the country.

Our Z-Zero XD was arguably the first carbon gravel bike, leadnig the way with disc brakes and wide, high volume, low pressure tires. The Z-Zero XD paved the way for what now defines a modern gravel bike. This pioneering design excels in all on and off-road riding disciplines and features all the carbon fiber expertise we’ve acquired over the past two decades.

All Z-Zero XD models include:

Carbon dropouts and bearing races: Our compression molded carbon parts allow us to reduce the metal content in the Z-Zero to less than 20 grams. Eliminating metal correctly in any carbon composite structure translates to lighter weight and better durability.

PARLEE tube joining process: Pioneered on the Z1, our exclusive molding process is the technical benchmark for fusing carbon fiber tubes into a monolithic structure. Our process is neither “lugged” or traditional “tube to tube” construction. The Z-Zero joining process is more precise, more costly, and unmatched in strength, using only carbon fiber to fuse each tube to another in a manner that yields a wholly unified structure with almost zero redundant material.

Shaped, bladder-molded tubing: Our performance-based tube shaping allows for lighter overall tube weights and optimized tuning of the laminate schedule. A variety of tube designs allows us to perfectly tune the ride to each rider’s needs. Produced by hand, by our staff, here in Beverly, MA the Z-Zero tubes are 10-15% lighter on average than typical carbon tubing yet feature better torsional performance and more comfort.

Tapered head and steerer tubes: An innovation derived from the now industry-wide ISO testing protocols; tapered steerer and head tubes are hardly news anymore, however, with our Z-Zero, we pioneered the use of the optimally sized 1.250” (32mm) inch lower standard over the heavier 1.500”(38mm) inch standard.  This provides the ideal balance for a road bike. Strength, safety, performance, and lightweight without harshness.

Disc Brake compatibility: The standard for the future, disc brakes for road bikes present a range of new options for brake, wheel, and drive systems. The Z-Zero was designed from inception to be disc brake capable. We use the modern thru-axle standards both front and rear for optimum performance and handling. The Z-Zero RD is compatible with 12mm front and rear thru-axles and the latest flat-mount calipers from Shimano, SRAM, and Campagnolo.

100% Hand-made

Every Parlee Z-Zero is made in our state-of-the-art facility in Beverly, MA.
