The CEEPO MAMBA-R Disc embodies the ultimate weapon for ITU triathlon, aero road and gravel. Designed in Japan by the triathlon specialist brand founded in 2003, this UCI-approved frameset combines aggressive tri-specific geometry, surgical aerodynamics and all-terrain versatility. With its Toray® high-modulus OSMC carbon (Optimal Strength and Modulus Carbon), truncated aerodynamic profiles, integrated cable routing via FSA SMR stem and tire clearance up to 35 mm, the Mamba-R adapts to road, triathlon and gravel. Delivered as a complete kit (frame, monocoque carbon fork, reversible seatpost, FSA headset and FSA SMR stem), it offers low weight (1,120 g frame M) and exceptional stiffness for power transfer.

CEEPO philosophy and heritage

• 100% triathlon Japanese brand: Founded in 2003 by Joe Tanaka, CEEPO produces only carbon frames with triathlon-specific geometry, the result of years of R&D in the aero and time trial field.
• "Quiver killer" versatility: The Mamba-R can be configured for short/long distance triathlon (ITU, Ironman), road (sportives, Gran Fondo) or gravel, thanks to its reversible seatpost and generous tire clearance.
• Stinger heritage: The Mamba-R inherits the aero lessons from the Stinger and other CEEPO triathlon machines, with truncated airfoil profiles, asymmetric fork, asymmetric short rear stays and aggressive "on the rivet" geometry.

Carbon and construction

• Japan Toray® OSMC: Use of Toray® high-modulus carbon with solid inner moulding process, eliminating weak points and ensuring smooth internal surfaces to optimize stiffness, strength and compliance.
• Truncated aerodynamic profiles (truncated airfoils): All tubes (top tube, down tube, seat tube, chainstays, seatstays) adopt truncated and tapered airfoil sections to reduce drag and turbulence in headwinds, while maintaining competitive stiffness and lightness.
• Optimized weights: Frame 1,120 g (size M, bare) and fork 450 g (uncut steerer 300 mm, bare), for an ultra-light frame + fork assembly without compromising stiffness.

Aerodynamics and integration

• 100% integrated cable routing: Fully concealed cabling via FSA SMR stem (Vision/FSA SMR stem cable solution), for a smooth surface and clean aesthetics, compatible with hydraulic disc braking.
• Monocoque carbon fork: One-piece fork with aero profile, seamless integration with frame, wide flattened legs reducing drag and turbulence, extended crown tail to smooth airflow, optimal stiffness/compliance balance.
• Cleaned bottom bracket area: Clean and aerodynamic BB386EVO, massive asymmetric short chainstays for maximum power transfer, sprint stiffness and acceleration responsiveness.
• Aero low seatstays: Lowered seatstays with truncated airfoil profile and generous clearance, reducing turbulence and improving vibration management thanks to the natural absorption properties of carbon.

Geometry and standards

• Aggressive tri-specific geometry: Steep seat angle (74.5°), elongated top tube, optimized stack/reach for low and forward aero position ("on the rivet"), while preserving neutral and predictable handling inherited from classic road.
• Five sizes: 43 (XS), 46 (S), 49 (M), 52 (L), 55 (XL) with precise stack/reach printed on the frame for optimal fit.
• Flat Mount disc brakes: Flat Mount mounting, rotors up to 160 mm max., 12 mm thru-axles front (100 mm O.L.D.) and rear (142 mm O.L.D.) for stiffness, braking precision and safety.
• Tire clearance up to 35 mm: Compatible with 25-28 mm road tires, 30-32 mm modern road and 35 mm light gravel, allowing unlimited road/gravel versatility.
• Universal drivetrain compatibility: Compatible with Shimano (mechanical and Di2), SRAM (mechanical and eTap AXS), FSA, Campagnolo EPS, Classified PowerShift Hub, in 2x (chainrings 30-53T) or 1x (chainrings 30-53T) configuration.

WRS reversible seatpost and adjustments

• Wide Range Seatpost (WRS) reversible: CEEPO reversible aero seatpost, allowing generous fore/aft adjustment and complete position customization (aero triathlon or comfort road).
• FSA NO.55R 1.5" ACR headset included: FSA semi-integrated ACR headset, compatible with supplied FSA SMR integrated stem (lengths adapted by size: XS/S 80 mm, M 90 mm, L 100 mm, XL 110 mm).

UCI approval and track record

• UCI Legal: UCI-approved for all road competitions, sportives and draft-legal triathlon (ITU, World Triathlon).
• Team BIKE AID track record: Used by Team BIKE AID in road, gravel and triathlon competitions, with stage wins, jerseys (yellow, green, polka dot, white) and KOM, notably by Yoel Habteab at the Tour of Pyongyang.

Available variants

• Glossy Blue color: Elegant and modern glossy blue.
• Hirro Fade color: Subtle and exclusive fade.
• White color: Timeless and clean white.
• Chameleon color: Iridescent changing chameleon paint.
• Pink color: Bold and dynamic pink.

For whom?

The CEEPO MAMBA-R Disc is designed for demanding triathletes (ITU, Ironman 70.3/140.6), aero road racers (sportives, Gran Fondo, UCI competitions), and versatile riders looking for a single bike for road, triathlon and gravel. Its balance between aerodynamics, stiffness, lightness and versatility makes it a formidable machine for those who prioritize speed, pedaling efficiency and the ability to adapt to all terrains. Ideal for athletes who want to train on the road, sprint for KOMs, adjust position for triathlon, and venture off the beaten path with 35 mm tires.
