Feathery Carbon Bottle Cage FC-121 – Triathlon Aero Powerkit 3
More performance, more range, more comfort – with the FC-121 Aero Powerkit 3, you get a sophisticated system for maximum hydration and smart storage space utilization on your bike.

✔ Handcrafted & premium quality
Each bottle cage is carefully handcrafted and assembled with rustproof DIN stainless steel screws and matching washers – durable, robust, and designed to meet the highest demands of cycling.

✔ Flexible & secure
The adapter is adjustable in height and angle. Water bottles, tool boxes, or mini pumps can be stored directly behind the saddle – aerodynamic and within easy reach. Elite, SKS, Vaude, and Camelbak bottles up to 0.75 liters are held more securely and remain in place even when the holder is tilted vertically.

✔ More storage space, fewer breaks
Especially on small frames, the holder offers additional space for 1–2 bottles, spare cartridges, or tools. This reduces breaks and allows you to ride longer independently—perfect for triathlon, gravel, road bike, MTB, or touring.

✔ Compatible & expandable
A tool bottle or saddle bag can also be easily attached to the adapter – for even more flexibility on long distances.

✔ A truly unique item
Not a mass-produced product, but one of only 75 handmade items from m-bike parts, a company that has been synonymous with high-quality, customized bike components since 2009. Only selected quality products from around the world are used—fairly sourced and packaged in an environmentally friendly manner, primarily using paper and paper tape.
