79BIKE & Ventus Carbon Belt + Primary Pulley Kit
product description
REAL CARBON BELT. STAINLESS STEEL PULLEY.
Upgrade your 79BIKE Falcon GT / Falcon Pro or Ventus One / Ventus V1+ primary drive system with the SKRMOD real carbon fiber belt and stainless steel primary shaft pulley kit. Built for riders who want stronger power transfer, better pulley durability, faster mud release, and less maintenance in real off-road conditions.
Unlike basic belt and pulley kits, SKRMOD combines genuine carbon fiber belt reinforcement, a corrosion-resistant stainless steel pulley, and front + side mud-shedding ports — giving your drivetrain a cleaner, stronger, and longer-lasting upgrade for high-power riding.

KEY FEATURES
The SKRMOD primary drive upgrade focuses on what actually matters for hard riding: real belt strength, better pulley matching, stainless steel durability, and faster mud release.
- Genuine carbon fiber belt: Built with real carbon fiber reinforcement, not just a standard belt marketed as “performance.” Designed for stronger load resistance under aggressive riding.
- 19mm optimized belt width: Wider than the stock 16mm belt and designed to better match the stock and upgraded pulley width for more stable belt contact during power transfer.
- Stainless steel primary shaft pulley: More resistant to rust, corrosion, and long-term wear than ordinary coated steel pulleys. Because the protection comes from the material itself, it does not rely only on surface coating.
- Front + side mud-shedding ports: SKRMOD adds mud-release openings not only on the pulley face, but also on the side area — a detail many common pulley designs do not include.
- Lighter than common 45# steel pulleys: Compared with many ordinary 45# steel pulley designs, the SKRMOD stainless steel pulley helps reduce rotating mass and lower drivetrain load while keeping strong durability and a premium stainless steel finish.
We developed the primary pulley removal tool because removing the primary pulley can be difficult without the correct tool, especially for riders or shops that frequently disassemble the drivetrain for upgrades, repairs, or video builds.
Customer feedback:
WHY UPGRADE?
The stock primary drive system is fine for normal riding, but hard acceleration, upgraded power, mud, water, and sand can expose its weak points: faster belt wear, debris trapped around the pulley, and coated steel parts that may rust once the surface treatment wears down.
One kit, three real upgrades: a genuine carbon fiber belt for strength, a stainless steel pulley for long-term durability, and SKRMOD front + side mud-shedding ports for cleaner off-road performance.
If you ride harder than stock, run more power, or often ride through mud and water, this is the cleaner, stronger, and lower-maintenance primary drive upgrade your 79BIKE or Ventus deserves.
INSTALLATION
The optional SKRMOD pulley removal tool is designed to make primary pulley removal and installation easier for 79BIKE and Ventus drivetrain service.
- Full Set Tool (3-Piece): Fits both pulleys and 2.3 / 2.5 chain drive sprockets.

FAQ
Is this a 79BIKE carbon fiber belt upgrade?
Yes. This kit is designed for compatible 79BIKE Falcon GT and Falcon Pro primary drive setups.
Does this fit Ventus One or Ventus V1+?
Yes. This product is made for compatible Ventus One / VTB Ventus One and Ventus V1+ / Ventus One Plus primary belt-drive systems.
Why upgrade to a 19mm carbon fiber belt?
The 19mm belt, upgraded from the stock 16mm width, is designed to better match both stock and upgraded pulley widths, providing more stable belt contact during power transfer while improving strength and durability for high-power riding.
Should I replace the pulley when upgrading the belt?
Yes, it is recommended. A real carbon fiber belt is harder than a standard belt, so pairing it with the SKRMOD stainless steel primary shaft pulley helps improve wear resistance and long-term drivetrain life.
