Ventum GS1 gravel bike, current generation with 47mm tire clearance. Purchased in spring of 2023 and ridden around 1,200 miles on it since. Has its share of scratches as shown in the photos, but mechanically the bike is flawless. Original price around $7,700

Let's discuss the most interesting part of the build first!
The wheels are Protens SC51 from a German small business similar to Cantu here in the US. His selection of carbon hoops laced to these really cool Trailmech hubs manufactured in Ukraine. The rims are 51mm deep with a 25mm internal. The hubs use a clutch mechanism in the freehub similar to the DT Swiss star ratchet, except with a concave/convex fitment between the rings for an even stronger engagement and less friction when freewheeling. The one downside to these is that the freehub runs on oil rather than grease (grease clogs it up) so it has to be serviced a bit more regularly. Luckily it's super easy to work on! All this said, if you don't want the wheels I'll sell the rest of the bike for $800 less. Rotors and cassette will still be included. Some posts from Protens and Trailmech below:

The remainder of the build is more straightforward.
Shimano GRX 800 Di2 2x11 drivetrain, including:
- ST-RX815 Brake/Shift Levers
- BR-RX810 Hydraulic Brakes
- SM-RT86 160mm 6-bolt Brake Rotors
- FC-RX810 Crank, 172.5mm with 48/31 chainrings
- FD-RX815 Front Derailleur
- RD-RX815 Rear Derailleur
- Seatpost Internal Battery (BT-DN300 I believe)
- SM-BCR2 Battery Charger (plugs into interface in handlebar)

The finishing kit is as follows:
- ENVE In-Route Aero Road Stem, 120mm (custom request not done on normal builds)
- ENVE Aero Road Handlebar, 42cm (flares to 47cm at drops)
- ENVE Integrated accessory mount, with Garmin top and Go-Pro style bottom attachment
- Ventum Carbon Seatpost
- Fizik Argo Saddle, 150mm
- Brooks Cambium Bar Tape
- Specialized Pathfinder S-Works Tires, 700x42mm. 1,200 miles on them

And that's it! Shipping is available using Bike Flights / UPS, will split price with buyer 50/50.

Ask any questions, I'm happy to answer.
