FIT Bike Co -SHANE HALAHAN SIG. SQUIB 20.75″ TT BLUE ANGEL (20″ WHEELS)

FIT Shane Halahan Signature Squib 20.75″ Frame

The FIT Squib is Shane Halahan's signature frame designed for smaller riders transitioning to a full-size 20″ BMX bike. Featuring trails and transition-focused geometry with a slack 74.5° head tube angle and low 11.5″ bottom bracket, this frame prioritizes stability for jumping and ramp riding while maintaining a proportionate 8.25″ standover for younger or shorter riders. Built from 100% chromoly and manufactured in the USA.

Key Features

• Smaller rider geometry – 20.75″ top tube length and 8.25″ standover height provide proper fit for younger riders or adults under 5'6" moving up from 18″ or smaller bikes
• Trails/transition-optimized angles – 74.5° head tube angle and 71° seat tube angle create stable, predictable handling for jumping, pumping transitions, and landing from height
• Low 11.5″ bottom bracket – lower BB height increases stability and lowers center of gravity for confident landings and smoother pumping on transitions
• 13.5″ rear end – shorter chainstays improve maneuverability and make the bike easier to manual and hop while maintaining stability for jumping
• 100% chromoly construction – full 4130 chromoly tubing throughout with 4-quadrant post-weld heat treatment on dropouts provides strength without excess weight
• Integrated seat clamp and headset – built-in seat clamp and integrated headset reduce external parts, weight, and potential maintenance points
• Made in USA – domestically manufactured by FIT with consistent quality control

Compatibility and Ideal Use

This frame is designed for smaller riders (typically 4'10" to 5'6") looking for a full-size 20″ bike with geometry suited to trails, park, and transition riding. The slack head angle and low BB make it less responsive for technical street riding compared to steeper, taller frames. Requires an integrated headset, mid BB cranks, and 14mm rear axle. Removable brake mounts support U-brake or gyro setups, but no gyro tabs are included—requires detangler or brakeless setup for bar spins. Best suited for riders focused on jumping, pump tracks, skateparks, and transition riding who need a frame sized appropriately for their height.
