In an impressive display of technical component selection, Oleg, from Twisted Wheels YouTube Channel, has created a Colnago C64 road bike weighing just 6.78 kg – breaking the UCI's weight limit of 6.8 kg. At the heart of this build are our FARSPORTS EVO S6 wheels (2024 version), complemented by a carefully curated selection of lightweight components such as FARSPORTS F1s Handlebar. You can watch the full build video at the end of this post.

The Foundation: Colnago C64 Frameset Specifications
The build begins with a Colnago C64 frameset in size 52s, featuring:
- Frame weight: 1.1 kg (including seat clamp, derailleur hanger, and pressed headset)
- Fork weight: 426g with integrated preload bolt system
- Fully internal cable routing system
- Large threaded bottom bracket shell (BB30/DUB compatible)
- Handcrafted in Italy with distinctive carbon lugs
- Proprietary D-shaped seat tube design

The Centerpiece: FARSPORTS EVO S6 Wheelset
The standout component of this build is the FARSPORTS EVO S6 wheelset (2024 version), which offers an exceptional blend of aerodynamics and lightweight construction:
- 56mm deep carbon fiber rim profile
- Ceramic Speed bearings for reduced rolling resistance
- Full carbon spoke construction
- Exceptional aerodynamic performance (validated through independent testing by Hambini)
- Optimized for both straight-line speed and crosswind stability
- Compatible with tubeless and traditional clincher setups

Tire Setup
- Vittoria Corsa 28mm clinchers with tan walls
- Tubolito lightweight inner tubes for weight reduction without sacrificing reliability

Cockpit Selection
The cockpit setup demonstrates careful attention to both weight and aerodynamics:
- FARSPORTS F1 integrated handlebar system featuring:
- Full internal cable routing compatibility
- Integrated Garmin/GoPro mount
- Custom spacers for Colnago C64 compatibility
- Beyond carbon saddle weighing just 100g
- D-shaped carbon seatpost optimized for frame integration

Groupset Selection
SRAM Wireless System
- SRAM Rival eTap AXS shifters (chosen for aesthetics over Red, weight penalty of only 11g per shifter)
- SRAM Red DUB crankset (one of the lightest production cranksets available)
- SRAM Force XPLR rear derailleur (compatible with 44T cassettes, only 10g heavier than Red)
- Rotor 11-39T 12-speed cassette featuring:
- CNC-machined aluminum top 4 cogs
- Optimized gear spacing for road use
- Significant weight savings over SRAM 10-36T and 10-44T options
Braking System
- Hope RX Plus calipers specifically engineered for SRAM AXS integration
- Shimano Dura-Ace rotors selected for optimal heat dissipation
- Weight advantage over standard SRAM calipers

Technical Weight Achievement
The final build achieves 6.78 kg (14.95 lbs) while maintaining:
- Full riding functionality
- Two bottle cages
- Garmin and GoPro mounts
- Deep-section aero wheels
- Complete electronic shifting system
Real-World Performance
Oleg took the bike on a 3-week bike tour across Spain. The build demonstrated:
- Exceptional speed characteristics with the FARSPORTS EVO S6 wheels and Ceramic Speed bearings
- Notable acceleration and sustained speed capabilities
- Effective 1x gearing range with limitations only appearing above 55 km/h
- Impressive frame compliance despite the ultralight construction
- Stable handling characteristics at both high and low speeds
Conclusion
This Colnago C64 build, anchored by the impressive Farsports EVO S6 wheelset, demonstrates the current possibilities in ultralight bike construction. While it breaks the UCI weight limit, it stands as a testament to modern cycling technology and careful component selection, creating a fully functional sub-6.8kg road bike that excels in real-world conditions.
