Used Bike Frames for Sale

Building a bike from the frame up is one of the most satisfying ways to get exactly what you want, fit, feel, and style included. Whether you’re after carbon efficiency, steel soul, titanium forever-vibes, or aluminum value, a frameset is a blank canvas for the kind of riding you actually do.
We stock bike frames and framesets for sale across every discipline, road, mountain, gravel, cyclocross, and tri/TT. If you’ve already got a parts bin you trust, reuse what you love. If you’re starting fresh, pick the frame first and build around the details that matter: tire clearance, mounts, geometry, axle standards, and cockpit fit. Every Certified Pre-Owned frame we sell is professionally inspected and backed by 30-day returns, so you can build with confidence.

Road Bike Frames

Road frames are light, quick, and built to excel on pavement, whether you’re training, racing, commuting, or just chasing miles. From classic steel framesets to modern aero builds, our inventory includes everything from endurance-friendly geometry to race-focused frames designed to hold speed.
enve road frame
The ENVE Melee road frame is designed to ride fast, treat you nice, and welcome you back the next day. This is love, not lust.

Mountain Bike Frames

We carry a large selection MTB frames for sale, including hardtails and full-suspension frames across XC, trail, and enduro. Mountain bikes live hard lives, so we inspect frame integrity and suspension function, then document condition clearly so you know what you’re getting before you build.
 
trek fuel ex frame
The Trek Fuel EX is a perfect MTB frame to build a "do everything" bike. Pedal all day in the backcountry or laps in the park, this frame does it all. 

Gravel Bike Frames

A gravel frameset is an open invitation. These bikes can be built for fast dirt, mixed-surface adventure, or loaded bikepacking, depending on how you spec them. When choosing a gravel frame, pay attention to tire clearance, mounts (rack/fender/top-tube), stack and reach, bottom bracket standard, and whether it supports 1x, 2x, or both.
ENVE MOG gravel frame
The ENVE MOG gravel frame was designed to go fast and inspire confidence, over any terrain you deem appropriate. With six frame sizes and three unique fork rakes across the size run (many brands only offer 1 or 2) the MOG has been designed to ensure that optimal handling is achieved regardless of frame size.

 

Triathlon Bike Frames

Triathlon and TT frames are built for one thing: speed. These framesets are often a great used value, and building from a frame lets you dial in the biggest performance variable of all, your position. Pick your cockpit, crank length, and wheel setup around your fit and goals, then go hunt PRs.
cervelo tt frame
The P5 is Cervélo’s flagship TT bike. It serves as the foundation for the groundbreaking P5X platform. For years, the P5 has owned its status as a legend for its acute performance, responsive handling, and adjustable fit.

If that sounds like you, it might be worth it to think about building your own bike component by component, from the frame up. Read the full article here.
