The Parlee Z-Zero Disc is 100% made to order, with the optimum performance characteristics and technical requirements perfectly met for each individual rider. From gravel epics to gran fondos, no road bike can match the versatility of the Z-Zero Disc.  We are able to plan the custom build of your Parlee Z Zero bike from geometry and carbon selection all the way through to every component on the bike. This is the ultimate combination of our Retül Frame Selection Bike Fit Service combined with our Custom Bike Building Service.
The Parlee Z-Zero RD was the first carbon fiber road bike to embrace both disc brakes and wider, high volume, lower pressure tires, paving the way for what now defines a modern road bike. This pioneering design excels in all road riding disciplines and features all the carbon fiber expertise we’ve acquired over the past two decades.

• Handmade one at a time in Beverly, Massachusetts
• Available custom geometry
• One-of-a-kind nude carbon finish standard
• Parlee Paint Lab custom paint is also available

From mixed surface exploring to all-day races, sportifs and gran fondos, no other road bike can match the timeless versatility of the Z-Zero RD.

All Z-Zero RD models include:

Carbon dropouts and bearing races: First used on the Z5, our compression molded carbon drops and bearing races (in the head tube and bottom bracket) 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.
