Reviews & Ratings
The reviewer discusses a VeloBuild carbon fiber gravel bike frame they purchased. They chose it over other options like the Icon GRO due to its 50mm tire clearance, aero seatpost, UDH compatibility, and low price of around $700 including handlebars and delivery. They praise the build quality, the UD raw carbon glossy paint that fades to black, and the ceramic T47 bottom bracket. The frame is described as not the lightest (around 1200g for size 52) but still light, and it forms the core of a complete bike build that weighs 7.7kg and costs under $3,000.

The VELOBUILD GF-005 is a Chinese carbon fiber gravel bike frame praised for its low price, light weight, and versatility. Users report it as a budget-friendly option that performs well on both road and gravel, with aero features and generous tire clearance up to 2.1 inches. However, quality control issues like resin excess in bearing seats and proprietary seatpost limitations are noted. It's seen as a 'one-bike-fits-all' solution for non-competitive riding.
AI Summary
Pros
- Very low price with no taxes/customs via XDB shipping
- Lightweight frame (around 1075g for XS, 1200g for S with hardware)
- Excellent versatility: performs well on road and gravel, with high tire clearance (up to 2.1")
- Aero design and good ride quality, faster than some comparable bikes
- Good paint finish and visible carbon weave
- Well-made internal frame construction (latex mould)
Cons
- Quality control issues: excess resin in headset bearing seat requiring Dremel fix
- Proprietary seatpost with limited offset options (0mm and 20mm only)
- Missing parts in delivery (e.g., offset seatpost)
- Clear coat scratches easily and can be damaged by fluids like DOT brake fluid
- Loud freehub on some wheelsets (e.g., Elite wheels)
- Limited seatpost insertion depth, may require cutting for taller riders
Key Points
- Carbon fiber material
- Frame weight ~1075-1200g depending on size/hardware
- Tire clearance up to 2.1 inches (53mm)

The VeloBuild Carbon Fiber Racing Gravel Bike Frame (Aero Grav) is a budget-friendly, open-mould carbon frame inspired by the Ridley ASTR RS, offering similar aggressive, race-oriented geometry. It features a T47 bottom bracket (86.5mm inboard), UDH hanger, and claims 50mm tire clearance (though real-world fit is tighter, with 52mm rear possible with 1x and careful tire selection). The frame includes a proprietary aero seatpost (available in 0mm and 20mm offset options) and integrated or semi-integrated cockpit options. Typical weights are around 1100-1300g for the frame (size-dependent) and 450-500g for the fork. Price is approximately $500 for the frameset, with custom paint available for an extra fee. Users report it as stiff and fast, suitable for all-road and gravel racing, but note compromises in comfort, tire clearance, and build quality. New builds show compatibility with SRAM 13-speed E1, 2.1" MTB tires (e.g., Thunder Burt), and 52T 1x chainrings, though front derailleur mounting may limit 2x to 50T max. Headset bearings are low quality and seatpost can stick. Paint is fragile.
AI Summary
Pros
- Excellent value for money, offering high-end features like T47 BB, UDH, and aero design at a very low price point.
- Fast, race-oriented geometry and stiff frame provide responsive handling and good power transfer, making it feel quick on road and gravel.
- Versatile as an all-road bike; can be built with multiple wheelsets (road and gravel) and handles well on mixed terrain.
- Good build quality for the price, with clean internal moulding, decent paint options, and generally well-faced interfaces (BB, brake mounts).
- Wide gear compatibility: supports 1x chainrings up to 48T (with careful setup) and 2x up to 53T, accommodating various groupsets.
- Can fit 2.1" MTB tires (e.g., Thunder Burt) with careful selection, offering real off-road capability.
- Compatible with SRAM 13-speed E1 groupset and various 1x/2x drivetrains with minor adjustments.
Cons
- Tire clearance is overclaimed; actual max is around 50-52mm measured width, with very tight chainstay clearance, limiting true 2.2" MTB tire fit.
- Very stiff and harsh ride quality, with minimal compliance from the frame and aero seatpost, requiring careful tire pressure and selection for comfort.
- Frequent shipping delays and poor communication from VeloBuild, with unrealistic timelines and lack of updates causing frustration.
- Headset assembly issues are common, including play, poor preload, and compatibility problems with compression rings and expander plugs.
- Paint quality is fragile and prone to scratching; custom paint jobs can be inconsistent or poorly executed compared to requests.
- Proprietary components: seatpost and integrated cockpit limit aftermarket options, and some parts (like rear axle thread pitch) may not match modern groupsets without replacement.
- Headset bearings are low quality and prone to rust; seatpost can get stuck in the frame.
- Front derailleur mounting height may be insufficient for chainrings larger than 50T in 2x setups.
Key Points
