Product Details
You did it. You finally found your dream bike. It has all the features you'd want, and it seems perfect for how you envision riding it. The only issue? Color. Maybe you're lukewarm on how it looks, and there's one nagging part that prevents you from truly loving the bike. Perhaps your friend already has a bike that color, and you'd never want to be seen matching someone else. Luckily for you, OPEN has a solution: the New OPEN U.P. Unbeaten Path Gravel Frameset (Ready to Paint). RTP, or "Ready to Paint," is the blank canvas of a bicycle that you deserve to build your dream bike.
As one of the premier gravel bikes available on the market, the U.P. easily accommodates a 700 x 40c tire or a 27.5 x 2.1" mountain bike tire. It offers the flexibility to use more conventional 28mm road tires or cyclocross rubber up to 40mm wide—no other bike offers such versatility. The U.P. was originally designed as a fat tire road bike and boasts geometry that remains true to its road bike roots. This ensures smooth handling, peppy acceleration, and a fit that is characteristic of high-performance road bikes.
The U.P. features advanced carbon fiber construction, ensuring durability and a lightweight feel. With its innovative design, the U.P. delivers a balance of speed and comfort, making it suitable for a range of riding conditions. All you need to do is decide where your next adventure will take you, install the appropriate wheels and tires, and let the OPEN Cycles U.P. guide you on your journey. The Ready to Paint frameset allows you to customize your bike's appearance to match your style and personality, ensuring that your dream bike is uniquely yours.
