DescriptionBike Weight Truly Matters Introducing the Blue Sky 20, where bike weight truly matters! Crafted meticulously in small batches, each frame features double-butted 7005 aluminum tubing for optimal strength and weight efficiency. With super-clean internal cable routing, forged dropouts, and post-mount disc brake mounts both front and rear, the Blue Sky 20 ensures a smooth and controlled ride. Starting in the low 19-pound range with the Pro Deore model, our focus on high-quality component selection ensures exceptional performance. Noteworthy details include our new lightweight 127mm Trailcraft aluminum spindle direct mount cranks, offering your choice of 28 or 30-tooth narrow-wide style chainring to minimize weight without compromising strength. The Blue Sky 20 Pro model elevates performance with our Stans Crest MK4 Custom 1050-gram wheelset. Expertly laced hubs, lightweight rims, and Ashima 85-gram 160mm rotors provide optimal stopping power while maintaining a super-lightweight profile. Often overlooked, rotor selection plays a crucial role in reducing rotational weight, enhancing the riding experience for both beginners and seasoned riders alike. For enhanced control and comfort, our TC30 air-sprung suspension 80mm fork stands as the lightest 20" fork available. Combined with BIG tubeless tires, it smooths out rough terrain, allowing for longer, more enjoyable rides with your young rider. Customizable Component Selection: Tailored to Your Preferences Our commitment to customizable options extends to component selection. The Pro model 1x10 group features Shimano Deore brakes, a Shimano Deore shifter, and a Shimano Zee rear derailleur, ensuring low weight and high performance. Alternatively, the Special Build Level 1x10 components offer Microshift 9-speed components and Shimano MT-201 hydraulic disc brakes, balancing weight, performance, and budget. The Ultimate Goal: The Lightest Production 20” Trail Bike The ultimate goal? To build the lightest production 20” trail bike, requiring no further modifications. Designed and built in Colorado, the Blue Sky 20 boasts super-light components, including our TC30 carbon fiber suspension fork and alloy spindle direct mount crankset. Choose your preferred chainring size based on your terrain, and enjoy the convenience of water bottle compatibility, a rarity in this category. Versatile Performance: Ready for Any Adventure Whether racing, hitting the trails, or exploring parks, the Blue Sky 20 delivers next-level performance and versatility.
