SRAM RockShox DebonAir air spring upgrade kit. I pulled this from a 2023 160mm zeb. It’s in good shape.

High-performance Diaz Suspension Design Runt air spring upgrade is black and compatible with RockShox ZEB forks. 160mm piston currently installed and I may have a 190mm piston somewhere.

Frame: Cube K24 (24" Wheel Size) Forget the heavy, sluggish, entry-level factory builds. If you want your kid to love climbing as much as descending, this is the bike. Up for grabs is a heavily customized Cube K24 that has been systematically upgraded with top-tier, lightweight adult-spec components. The Cube K24 frame is known for its excellent kid-friendly geometry, but we took it to the next level to build an absolute trail weapon—incredibly light, fast-rolling, and equipped with premium stopping power for smaller hands. Premium Upgrade Highlights The Wheelset (Custom & Ultra-Light): * Hubs: American Classic (super light, fast engagement, and a great freehub sound!) Front Rim: Box Components Rear Rim: Stan’s Crest (the gold standard for lightweight, tubeless-ready performance) Cockpit & Control: Shifter: Shimano XTR 11 speed (Top-of-the-line, crisp shifting with an incredibly light lever throw—perfect for kids' hands) Brakes: Shimano XT Hydraulic Disc Brakes (Unmatched stopping power and modulation, featuring adjustable reach for smaller fingers) Stem: Hope CNC Machined Stem (Premium boutique bling, short and snappy for confident steering) Why this matters: Stock kids' bikes are notoriously heavy and come with stiff shifters and weak plastic brakes. The XTR shifting and XT hydraulic brakes on this Cube K24 completely change the game, giving young riders total confidence and control on real singletrack. Condition & Maintenance The bike is mechanically dialed, clean, and ready to hit the dirt. Because it features high-end components, it has been meticulously maintained. Expect the usual minor cosmetic scuffs and scratches on the K24 frame and crank arms from normal kids' trail riding, but there are absolutely no dents, structural issues, or mechanical flaws. Tires have plenty of tread left.

Freehub: SRAM XD Driver (For SRAM 11 or 12-speed mountain cassettes) Hub Spacing: Boost 12x148mm Score a top-tier carbon enduro/trail wheel upgrade at a massive discount. Up for sale is a brand new, never ridden Stan's NoTubes Flow CB7 carbon 29er rear wheel. The Flow CB7 is widely regarded as one of the best all-around trail and enduro carbon rims available. It utilizes Stan's proprietary RiACT radial compliance technology, allowing the rim to absorb harsh trail impacts and vibrations vertically while remaining incredibly stiff laterally for precise tracking through corners. Condition & Details The Story: A tire and an XD cassette were mounted to the wheel for a mock-up build, but the bike was never completed or ridden. It has exactly zero trail miles on it and has never seen dirt. Cosmetics: The carbon rim, spokes, and hub are in absolutely pristine, flawless showroom condition. Tubeless Tape: There are some light cosmetic scuffs and mounting marks on the pre-installed factory tubeless rim tape from when the tire bead was pushed on. The tape is still 100% airtight and perfectly functional, so it is ready to be loaded with sealant and ridden immediately. Premium Technical Specs: Rim Material: Premium Carbon Fiber with a stealthy grey/black finish. Internal Rim Width: 29.0mm (35mm outer width) providing superb tire sidewall support. WideRight Profile: Specifically optimized for modern 2.35” to 2.80” trail and enduro tires to maximize traction without distorting the tread pattern. Asymmetric Construction: Built with an asymmetric rim shape and offset drilling to balance spoke tension and create a much stronger, more durable overall wheel build. Spokes: Premium Sapim Force Black spokes with Secure Lock aluminum nipples. Brake Rotor Interface: 6-Bolt Why buy this? You are getting a brand-new, top-of-the-line $1,150 carbon wheel for a fraction of the cost just because a tire and cassette were briefly test-fitted on it. Your gain, my loss! Serious offers only.
