The ultimate race solution for €5,999
The new Leeze ONE
Since 2012, Leeze has been guided by a clear vision: Pursue your passion.
Racing experience, D2R development, and the Leeze Factory Racing Team have proven one thing: true performance comes only from the perfect interplay of all components. The Leeze ONE brings exactly that to the road. An uncompromisingly tuned aero system—developed for racing, ready for new personal bests.
Born out of a genuine passion for cycling. And because this is exactly the bike we want to ride ourselves: LEEZE ONE – The only ONE you need to be fast.
Leeze Aero Cockpit
Maximum aerodynamics and seamless integration for peak performance on the road. With a 70 mm reach, 120 mm drop, and 4° flare, as well as handlebar widths ranging from 380 to 420 mm and stem lengths from 80 to 120 mm, it is perfectly tailored to modern racing demands.
All in Aero
From the digital wind tunnel straight to the racetrack: the complete setup for uncompromising race performance. Perfectly tuned components come together to form a race-proven total solution for maximum speed.
Race Geometry
All parameters work in tandem:
Stack, reach, seat angle, head angle, and bottom bracket height are precisely tuned to one another, creating a geometry that combines race aerodynamics, handling, and pedaling efficiency into a single, integrated system.
LEEZE ONE PRO Meteorite Grey
With the Leeze ONE, we’ve channeled our expertise in wheel development, D2R aerodynamics, and racing into an uncompromising aero race bike.
Race-ready and tuned for maximum speed, precise handling, and true race performance.
Race Ready: The Leeze ONE Team
Shimano Ultegra Di2
We equip the Leeze ONE with Ultegra Di2 for consistent shifting performance when it counts. Extra-short cranks ensure optimized pedaling efficiency and provide additional clearance in fast corners.
D2R: Fast and controllable under real-world conditions.
ONE Aerodynamics
A narrow front profile, a deep head tube, and an aerodynamically optimized down tube reduce drag in the critical area.
All profiles are based on Kammtail shapes with defined trailing edges, resulting in higher aerodynamic efficiency, increased lateral stiffness, lower weight, and greater stability in crosswinds—while also offering increased vertical compliance for added comfort.
When sprints get faster and races get longer.
Lowered Aero Seat Stays
The reduced size of the rear triangle increases stiffness between the crankset and the rear wheel, ensuring direct power transfer.
The lowered seat stays work in conjunction with the seatpost to increase vertical compliance, thereby improving comfort during longer races. Their shape directs airflow through the frame triangle to the Leeze Pro wheels.

A compact reach combined with a longer stem allows for an efficient, aerodynamic riding position.
The result: high stability at speed and precise, responsive handling.
The 72.5° steering angle ensures agile, intuitive handling with clear feedback—especially during fast turns and when changing direction.
- XS: 90 mm stem, 380 mm handlebar width
- S: Stem 110 mm, handlebar width 380 mm
- M: Stem 110 mm, handlebar width 380 mm
- L: Stem 120 mm, handlebar width 400 mm
- XL: 120 mm stem, 420 mm handlebar width
The 0-offset seatpost, combined with an effective seat angle of 74° (75° XS / 73.5° XL), positions you in an active, powerful stance over the bottom bracket.
This improves power transfer and promotes efficient pedaling.
A 20 mm setback seatpost is available as an option.
The slightly raised bottom bracket increases pedal clearance and allows you to keep pedaling even when cornering.
Ideal for aggressive acceleration and attacks coming out of corners.
Shorter cranks (165 mm in XS/M, 170 mm in M/L/XL) improve pedaling efficiency, open up the hip angle, and allow for a more dynamic, aerodynamic position on the bike.
The geometry follows a clear system:
S (52), M (54), and L (56) are deliberately close together, ensuring consistent, race-oriented riding characteristics.
XS (50) is even more compact & designed for smaller riders.
XL (58) offers taller riders a sporty position – without compromising the clean aesthetic.
