Winspace G3

Weight1480g
Year2025
CategoryFrame

The Winspace G3 gravel bike receives mixed reviews, with praise for its responsive handling, improved headset stability, and frame feel, but criticism for internal cable routing difficulties and a less compliant ride compared to the G2. Builders note challenges with proprietary components and routing, though the frame itself is considered high-quality.

Pros

  • Responsive steering and good geometry for racing position1
  • Improved headset stability over G2 due to traditional steer tube and larger bearings1
  • Frame feels flawless and gives confidence, comparable to steel bike in feel2
  • Internal cable routing was easier than anticipated initially1
  • Shifting performance is great with mechanical groupset2
  • Bike looks cool1
  • Full refund for returned groupset was processed without problems2

Cons

  • Less comfortable/compliant than G21
  • Seat post clamp interface is tapered and can slip under load; seat post shape is proprietary, limiting adjustment options1
  • Internal cable routing is difficult for tinkerers and became aggravating over time12
  • Power cable for electronic groupset did not fit through chainstay, causing frustration2
  • Manuals for Chinese parts are not great2
  • Oversized bars with internal cable routing add bulk (minor nitpick)1
  • Uncertainty about reliability of proprietary connectors2

Key Facts

  • Head tube angle is 70.5 degrees1
  • Frameset is carbon with internal cable routing12
  • Seat post clamp uses a tapered interface with recommended torque of 13 Nm with carbon paste1
  • Traditional steer tube with larger bearings1
  • Compatible with both electronic and mechanical groupsets, but electronic cable routing through chainstay can be problematic2
  • Frame size medium, available in pink color1

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.
