FIT Bike Co 2026 Series One – Smoke Chrome 20.5″ TT

Product Overview

The FIT Bike Co 2026 Series One is an all-around complete bike built on FIT's original frame design dating back to 2000. Featuring a 20.5″ top tube with chromoly front triangle, this bike balances versatile geometry suitable for street, park, and trails with updated 2026 components including a CNC-machined integrated headtube and fully sealed front hub. The S1 geometry provides neutral handling characteristics that work across multiple riding styles without favoring any single discipline.

Key Features

• Chromoly front triangle – Cro-Mo construction on head tube, top tube, and down tube provides strength and durability for diverse riding applications
• CNC-machined integrated headtube – Precision-machined headtube (new for 2026) ensures accurate bearing seat tolerances and clean aesthetics with integrated headset design
• Fully sealed hubs front and rear – Complete sealed bearing system on both wheels (upgraded front hub for 2026) reduces maintenance and improves longevity
• Lightened frame and fork – Updated construction reduces weight while maintaining S1 strength standards
• 33mm fork offset – Balanced offset provides stable yet responsive handling suitable for multiple riding styles
• Integrated headset with gyro holes – Low-profile headset design with optional brake gyro compatibility for 360° bar spins
• 2.4″ tires on S1W rims – Wider tires allow lower pressure for improved grip and impact absorption across various terrain
• Versatile S1 geometry – All-around frame design works for street, park, trails, and general riding without geometry compromises

Compatibility and Ideal Use Cases

The Series One 20.5″ is designed for riders approximately 5'6″ to 5'10″ who want a versatile complete bike that performs across multiple riding styles. The 20.5″ top tube and 165mm cranks are proportioned for average-height riders, while the neutral S1 geometry provides balanced handling that works equally well for street obstacles, skatepark transitions, dirt jumps, and general riding. Best suited for riders who don't specialize in a single discipline or those who want one bike capable of handling diverse riding sessions. The 33mm fork offset sits between aggressive street setups (typically 25–28mm) and stable park geometries, providing responsive steering without twitchiness. The sealed hubs and upgraded integrated headtube reduce maintenance requirements and improve long-term durability. The 2.4″ tires work across various surfaces and allow pressure adjustments based on riding style—lower for street grip and transitions, higher for dirt and trails. Also ideal for intermediate riders progressing their skills across multiple disciplines, or experienced riders who want a reliable all-around bike without needing multiple specialized setups. The versatile geometry makes this bike less optimized than purpose-built street or park frames but more adaptable for riders who session different terrain regularly.
