Let me be straight with you: when I first got serious about gravel cycling, the price tags nearly put me off the whole idea. Trek, Specialized, Cervélo, asking €5,000, €6,000, even more for their flagship gravel machines. And for what? A carbon frame, electronic shifting, and a badge on the head tube. I know this world well. I’ve ridden enough Belgian back roads and gravel paths to know that what matters is what’s under you, not what name is painted on it. That’s why Winspace’s gravel lineup stopped me in my tracks and I decided to give you my personal Winspace gravel bike review.
I’ve been riding Winspace road bikes for years now, and I’ll tell you plainly; the quality-to-price ratio on their road bikes is extraordinary. When they launched their G-series gravel bikes, I had to know whether the same formula applied. Spoiler: it does, and then some. You can check the full gravel lineup on Winspace’s official website (winspace.cc/collections/gravel-complete-bikes), but in this article I’m going to break down everything you actually need to know. Including the key differences between the Winspace G3 and G5, and how both compare against the big Western brands.
If you’re sitting on a budget of €4,000–€6,000 and considering a premium gravel bike, this Winspace gravel bike review article is for you.
The Winspace Gravel Family — and Why There’s No G4
Before diving into specs, here’s a detail I love about Winspace: their gravel range jumps directly from G3 to G5. There is no G4. Why? Because in Chinese culture, the number four is considered unlucky. It sounds similar to the word for death. So Winspace skipped it entirely. It’s a small thing, but it’s the kind of cultural authenticity that reminds you these are real people building real bikes, not just a faceless factory.
So you have the G3, Winspace’s established all-terrain gravel platform and the newer G5, which debuted with significant fanfare at Eurobike 2026. The G5 represents a major step up in ambition for Winspace’s gravel programme. Both bikes share Winspace’s commitment to Toray carbon and obsessive value engineering, but they target quite different riders.
Winspace Gravel Bike Review: The Winspace G3 — The Proven All-Terrain Performer
The G3 is the bike that put Winspace gravel on the map, and it’s easy to see why. This is a machine built for versatility. Equally at home on Belgian farm tracks, French gravel roads, or mixed-surface audax routes.
Frame Construction and Specifications
The G3 frameset uses a blend of T700, T800, and M40 carbon fibre. A layup that balances stiffness, compliance, and weight in a way that suits long days in the saddle. Key specs:
- Frame weight: ~950g (fork: ~450g)
- Bottom bracket: T47-68mm threaded
- Tyre clearance: 700c × 50mm (or 650b × 2.1″)
- Frameset price: $1,550
- 6 colour options: Lunar Grey, Pearl White, Carbon Black and more
- Build-to-order lead time: 10–15 business days
The tire clearance of 700c × 50mm is generous. Wide enough for serious mixed-terrain use. Whether you want a fast 40mm for gravel racing or a 50mm for bikepacking, the G3 accommodates it.
G3 Complete Bike Options and Pricing
Winspace offers three complete G3 builds, all with Shimano Di2 electronic shifting:
- G3 RS Di2 — $3,799: Entry point. Solid Di2 shifting, disc brakes, Lún wheels.
- G3 Pro Di2 — $4,099: Upgraded components. The sweet spot for most riders.
- G3 Ultra Di2 — $4,449 (on sale from $5,099): Top-tier build. Premium Lún wheelset.
All three builds include integrated handlebars, hydraulic disc brakes, and Winspace’s own Lún wheelset.
Winspace Gravel Bike Review: The Winspace G5 — A Purebred Aero Gravel Racer
If the G3 is the all-rounder, the G5 is the weapon. Winspace describes it as a purebred aero gravel racer. Built for speed on tarmac and confidence off-road. This is for the rider who lines up at the start of a gravel race, not just rides gravel for fun.
What Makes the G5 Different
The G5 frameset costs $2,200. a $650 premium over the G3. Key upgrades:
- Significantly more aerodynamic frame profile
- D-shaped seatstays borrowed directly from the T1600 road race frame
- More race-oriented stack and reach geometry
- Wide tyre clearance retained for all-terrain versatility
- 4 colourways: Nautical Blue, Dune Fade, Alpine White, Carbon Black
- Lead time: 15–20 business days (high demand)
G5 Complete Bike Options and Pricing
- G5 Pro Di2 — $4,799: Race-ready with Di2, disc brakes, Lún wheels.
- G5 Ultra Di2 — $5,199: Flagship build. Full specs:
- Groupset: SRAM RIVAL AXS XPLR (42T × 10-46T)
- Wheels: Lún GRAPID2 700C D45 with steel spokes
- Tyres: Michelin Power Gravel 700×40C
- Cockpit: Adventure Integrated Handlebar + aero carbon seatpost
- Complete weight: ~8.4kg (size M)
G3 vs G5 — Which One Is Right for You?
Choose the G3 if: You want a versatile, do-everything gravel bike and ride a mix of terrain. You do audax, bikepacking, or mixed long-distance events where comfort over many hours matters. You want maximum value. The G3 RS Di2 at $3,799 is one of the best-value carbon Di2 gravel bikes on the planet.
Choose the G5 if: You race gravel. You want a machine that feels fast on tarmac and gravel. You appreciate aero details and a more aggressive fit. As someone who has covered 630km in 24 hours, I understand the appeal of every watt saved, even on gravel.
What surprises me is how close the pricing is. For $300–400 more, you step up from proven all-rounder to dedicated aero racer. If your rides are more race-oriented, the G5 is a straightforward upgrade.
Winspace vs the Western Gravel Giants
Head-to-head pricing comparison
| Bike | Price | Drivetrain | Wheels |
| Winspace G5 Ultra Di2 | $5,199 | SRAM RIVAL AXS XPLR | Lún D45 carbon ✓ |
| Trek Checkpoint SL 7 AXS Gen 3 | $5,599 | SRAM Force AXS | Alloy |
| Specialized Diverge Expert Carbon | ~$5,500 | SRAM Rival AXS | Alloy |
| Canyon Grail CF SL 7 | $2,599 | Shimano GRX 12sp | Alloy DT Swiss |
| Winspace G3 RS Di2 | $3,799 | Shimano Di2 electronic | Lún carbon ✓ |
The pattern is consistent: across every price bracket, Winspace delivers more carbon, more electronic shifting, and better wheels than Western brands at equivalent money. The only thing the Western brands offer that Winspace doesn’t is a local dealer network and badge recognition. If those things matter to you, that’s your choice. But if you care about what’s actually under you, Winspace deserves serious consideration.

My Final Winspace Gravel Bike Review Verdict
Belgian roads have taught me a lot about bike quality. When you’re riding in the rain on cobblestones and gravel paths, when you’re 400km into a long ride and still have 200km to go, your equipment either earns your trust or it doesn’t. I’ve put thousands of kilometres on Winspace frames and I can tell you: they earn it.
The G3 is a brilliant, versatile gravel bike that will suit the vast majority of gravel riders at a price that makes Western equivalents look overpriced. The G5 pushes into race-focused territory while still undercutting the big names by a meaningful margin. Both bikes benefit from Winspace’s obsession with carbon quality and their direct-to-consumer model that keeps margins razor-thin.
If you’re in the market for a premium gravel bike, the honest advice is simple: do not buy from the big Western brands without at least looking at what Winspace is offering first. The value gap is too significant to ignore.
