FIT Bike Co Voelker Signature Young Buck Frame

Product Overview

The FIT Young Buck is Kole Voelker's signature frame designed for versatile riding across transitions, street, and park terrain. Built in the USA with investment cast components and Vari Wall Thermal-X tubing, it balances responsive geometry with durability for aggressive all-around riding. Features 75° head tube angle and 13.1" rear end for stability at speed and on transitions.

Key Features

• Vari Wall Thermal-X tubeset – Variable wall thickness tubing places material strategically for strength at high-stress areas while reducing weight in low-stress zones
• 75° head tube angle – Steeper head angle provides stable, confidence-inspiring handling on transitions and at speed without sacrificing street maneuverability
• 13.1" rear end length – Balanced chainstay length offers stability for transition riding while remaining responsive enough for technical street moves
• Investment cast seat clamp – Cast construction creates seamless integration with frame tubes and distributes clamping force evenly to prevent seat post slippage
• Integrated headtube (45°/45°, 41.8mm) – Modern integrated headset standard reduces stack height and provides clean aesthetic with improved bearing support
• 4Q-baked dropouts – 14mm dropouts with 0.250" thickness, heat-treated for maximum strength to resist bending and cracking from peg grinds and hard landings
• 11.7" bottom bracket height – Mid-height BB provides ground clearance for smooth pedaling through transitions while remaining low enough for stable landings and manuals
• Thread-on brake mounts – Accepts aftermarket thread-on 990-style brake kits (sold separately) for riders who want braking option
• Made in USA – Domestic manufacturing with quality control standards

Compatibility and Ideal Use Cases

This frame requires an integrated headset (45°/45°, 41.8mm), Mid/American bottom bracket, and 25.4mm (standard) seat post. Uses 14mm rear axle with 0.250" thick dropouts. If running brakes, purchase a thread-on 990-style brake kit separately. The 21.25" top tube suits riders approximately 5'8" to 6'1", though personal preference varies based on riding style. Ideal for riders who split time between transitions (parks, bowls, ramps) and street riding, where the geometry needs to handle speed and stability on transitions while remaining playful enough for technical street maneuvers. The slightly longer rear end and steeper head angle make it particularly well-suited for transition-focused riders who still want street capability.
