700C Fixed Gear Frameset Matte Black B (52cm)
The BSFHQS 700C fixed-gear frameset in Matte Black B offers a traditional track-focused geometry built from aluminum alloy. Available in multiple sizes including 52 cm, it targets riders seeking a lightweight frame with responsive handling for criteriums or city track sessions. The frame weight is listed around 1493 grams, with a fork approximately 665 grams. Specifications include a 28.6mm head tube (1 1/8″), 27.2mm seatpost, and BSA BB68mm threaded bottom bracket. Front QR is 100mm and rear QR 120mm, suitable for 700x25C tires.
With aluminum construction, riders can expect a stiff yet forgiving ride for sprinting and cornering. The frame’s durability supports aggressive riding styles, while the quick-release compatibility allows for easy wheel changes during training or events. This option is well-suited for riders who want a ready-to-ride track frame that balances weight and rigidity without compromise.
Key considerations include compatibility with 700C wheels, brick-by-brick assembly for fixed-gear setups, and ensuring the correct chainring and cog options align with the frame’s bottom bracket and spacing. Riders should verify fork compatibility and matching headset standards before purchasing components separately.
700C Fixed Gear Frameset Matte Black A (52cm)
The BSFHQS Matte Black A variant shares core aluminum track DNA with the other BSFHQS models, offering similar lightness and frame stiffness. It is available in 52 cm and includes the same 28.6mm head tube, 27.2mm seatpost, and BSA BB68mm threaded bottom bracket. Quick-release front and rear hubs are standard (100mm/120mm), and the maximum tire size remains 700x25C. This frame prioritizes precise handling and efficient power transfer for fixed-gear riders who value predictable responsiveness on urban tracks and training loops.
Features to consider include frame finish and compatibility with track-specific components such as fixed cog setups and appropriate chain tensioning. The 52 cm size aligns well with riders around five feet to five feet six inches tall, depending on inseam and riding style. As with any track frame, accurate wheel sizing and chainline setup are essential for smooth operation and safety.
Potential buyers should confirm seatpost diameter (27.2mm) and ensure the chosen fork matches the head tube diameter. Proper headset installation is also important to maintain steering accuracy and overall frame longevity.
700C Fixed Gear Frameset Blue 49cm
The Blue variant presents another aluminum track option in a smaller 49 cm frame, suitable for riders with a shorter reach or different proportions. The listed specs mirror the other aluminum BSFHQS frames: 28.6mm head tube, 27.2mm seatpost, and BSA BB68mm threaded bottom bracket, with 100/120mm QR spacing. This frame further expands fit options for riders seeking a compact track bike setup without sacrificing rigidity or feedback on fast descents and tight corners.
When choosing this frame, confirm your preferred tire clearance (up to 700x25C) and ensure your crankset, bottom bracket, and chainline align with fixed-gear requirements. A proper wheelset selection and brake compatibility, even for a C-type brake, will influence the frame’s overall performance on race day or weekend training rides.
POLSO FM007 INTRO7 Fixed Gear Frame (CR-MO GT Version)
The POLSO FM007 INTRO7 introduces CR-MO steel construction with a GT-style design. Available in 52 cm and 55 cm, this frame emphasizes durability and a classic appearance with internal cable routing and an integrated brake hanger. The steel composition offers different ride characteristics compared to aluminum, including slightly higher weight but excellent ride feel and fatigue resistance in fixed-gear use.
Pros for fixed-gear enthusiasts include robust threading for precise bottom bracket and headsets, plus a clean look from internal routing. The frame suits riders who prioritize longevity and a steel aesthetic while still pursuing fixed-gear efficiency. It is essential to verify compatibility with your drivetrain, including cog sizes, chain tensioning, and brake mounting standards. For many riders, this frame provides a reliable platform for a stylish, race-ready fixed-gear build.
Gravity FSX 1.0 Dual Full Suspension Mountain Bike
The Gravity FSX 1.0 is an aluminum-framed, dual full-suspension mountain bike. While not a track frame, it showcases aluminum construction and versatility across off-road riding. Features include front and rear disc brakes, easy-to-use shim shifters, and adjustable suspension, which broadens riding contexts beyond fixed-gear setups. This model is a practical reference for riders who want a balanced, all-terrain option that uses aluminum for lightness and stiffness.
When evaluating aluminum frames for track or street riding, it is important to separate dedicated track frames from general-purpose aluminum bikes. The FSX exemplifies a different category with suspension travel and disc braking, which can translate to an expanded perspective on how aluminum frames behave under different loads and road conditions. For fixed-gear builds, this example underscores how choice of frame materials influences ride feel and maintenance considerations.
Altogether, these five frames offer a mix of aluminum-focused track frames and related aluminum or steel options. Prospective buyers should weigh weight, rigidity, compatibility with fixed-gear configurations, frame height and reach, and how the frame interacts with wheels, tires, and brakes for their intended riding context.
Buying Guide: Key Purchase Considerations
Frame Material and Geometry
Aluminum frames deliver lightness and stiffness ideal for sprinting and quick handling on tracks. Check wall thickness, tube shaping, and the frame’s overall stiffness-to-weight ratio. Track-specific geometry influences acceleration, cornering, and tire clearance. Ensure the geometry aligns with your height, inseam, and riding style to reduce fatigue during long sessions.
Size and Fit
Fixed-gear track frames are typically available in multiple sizes. Verify reach, stack, and standover height. If ordering online, compare the size chart with your current bike measurements or seek expert fitting guidance to ensure a precise fit for safe, efficient riding.
Bottom Bracket, Headset, and Spacing
Many track frames use a threaded bottom bracket (such as BB68mm) and a 1 1/8″ head tube. Confirm the bottom bracket type, shell width, and compatibility with your crankset. Quick-release front and rear hubs are common for track frames, but verify axle spacing (100mm/120mm) to ensure wheel compatibility and proper cog alignment.
Brakes and Drivetrain
Fixed-gear frames typically use a single brake system or rely on track-specific stopping methods. When choosing a frame, confirm brake compatibility and spacing, as some frames emphasize caliper brakes or require specific brake mounts. Plan drivetrain components (chainline, cog sizes, chain tension) to achieve smooth operation and reliable braking control.
Weight, Durability, and Maintenance
Aluminum frames balance weight and durability well, but designs vary in weight by size and tube thickness. Consider maintenance access, such as cable routing (internal vs. external) and the ease of brake and wheel changes. Steel frames offer different ride characteristics, but aluminum remains the preferred choice for weight-sensitive track builds.
Final Considerations
When selecting a frame, consider your intended riding context: pure track racing, urban fixed-gear riding, or mixed use with occasional off-road capability. Compare the included hardware, compatibility with quik-release wheels, and overall build quality. Ensure you have a reliable source for parts and a plan for professional assembly if you’re new to fixed-gear setups.
