Winspace G3
Frame

Winspace G3

Weight1480g
Year2025
CategoryFrame

The Winspace G3 is a versatile carbon gravel frameset that improves on the G2 with better headset stability, modern standards, and a lighter, more aerodynamic design. However, it suffers from challenging internal cable routing—especially for electronic groupsets—and a proprietary seatpost clamp that can slip. Overall, it offers a stiff, race-oriented ride with a high-quality finish, but build complexity and weight are notable trade-offs.

Pros

  • Improved headset stability over G2 with traditional steer tube and larger bearings1
  • Responsive steering and good geometry for racing position1
  • Frame feels flawless and gives confidence; comparable to steel bike in feel2
  • Secure packaging, clean minimalist finish, multiple colors3
  • Modern standards: thru-axle, flat mount disc brakes, threaded T47 bottom bracket34
  • Multiple mounting points for bottles, fenders, and accessories3
  • High-quality FSA headset bearings included3
  • Versatile: suitable for 50% road, 50% gravel; accommodates various tire types4
  • Lighter than previous G2 model; aerodynamic features carried over from road models4
  • Asymmetric rear triangle and aluminum foil in carbon layup for added bottom bracket stiffness4

Cons

  • Internal cable routing is difficult and time-consuming, especially for electronic groupsets; power cable did not fit through chainstay21
  • Seat post clamp interface is tapered and can slip under load; proprietary seatpost shape limits adjustment1
  • Less comfortable/compliant than G21
  • Frame weight is not very light (1.5 kg for painted version); seatpost (186 g) and fork (463 g) also not light4
  • Manuals for Chinese parts are not great; some small parts included without clear instructions23
  • Uncertainty about reliability of proprietary connectors2
  • No size chart based on height; had to rely on geometry numbers3
  • Oversized bars with internal cable routing add bulk (minor nitpick)1

Key Facts

  • Frame weight: 1.5 kg (painted, with hardware); seatpost: 186 g; fork: 463 g4
  • Head tube angle: 70.5 degrees1
  • Bottom bracket: T47 threaded34
  • Fork: full carbon, round steerer tube (not D-shape), 100x12mm thru-axle3
  • Handlebar: Winspace Adventure, 400mm width, 95mm stem, 73mm reach, 117mm drop, 8° flare, full carbon3
  • Seatpost clamp is a tapered interface; recommended torque 13 Nm with carbon paste1
  • Internal cable routing with guides; compatible with mechanical groupsets34
  • Frame size Large: reach 38 cm, stack 58 cm3

Abusing the Winspace G3 Off Road

The reviewer discusses the Winspace G3 gravel bike, comparing it to the G2 model. They find the G3 to be a nice road bike with responsive steering, despite a slack head tube angle. They note it is less comfortable than the G2 but prefer its handling and appearance. A major improvement is the traditional steer tube and larger bearings, which prevent headset loosening. However, they experienced a seat post issue due to a tapered clamp interface, resolved with carbon paste and proper torque. They recommend a two-bolt rail clamp for better security.

Winspace G3 Built with Mechanical Brakes and Shifting

The reviewer builds a Winspace G3 gravel bike frameset, highlighting the internal cable routing and overall build process. They note that the internal routing was initially daunting but turned out easier than expected, though it became aggravating over time. The bike is built with a mix of used parts and new components like Lun Grip wheels and Panaracer GravelKing tires. After two early morning rides, the reviewer is enjoying the bike and plans to provide a full review later.

winspace g3 - this build was no fun

The reviewer discusses building a bike with a Winspace G3 frame. He initially used an L2 electronic groupset but had issues with the power cable routing through the chainstay, leading to frustration and eventual return of the groupset. He replaced it with an L2 mechanical groupset (GRT) and a Jaguire shifting kit, which worked flawlessly. He praises the frame's feel and confidence it provides, comparing it favorably to his old steel bike.
