VELOBUILD GF-005
FrameThe 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.
+4 more
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.

Key Points
- Frame material: Carbon fiber
- Bottom bracket: T47 (86.5mm inboard)

elitaone 3D Printed Bicycle Saddle Carbon Road/MTB Bike Competition comfort saddle 250x140mm
SaddleRecently tried three different cheap AliX Saddles for my "somewhat modern progressive forward fit" bike. Each about 40 Euros. Two 3D Printed Selle-SMP Copies: Elita One - 255x140mm-3DEX Really liked both SMP copies a lot! About as comfy as my old original Selle SMP. But not quite as ugly and way lighter. Ended up keeping the Goldix version as it has a bit wider front an nicer middle channel. Recommend both!
