Steel is real - Steel Gravel bike frameset with Gravel Adventure Carbon Fork. Tsunami Seaboard CX07

This is a steel gravel bike frameset with high end performance features which you can build a bike for all road rides on tarmac, PCN and gravel trails. The stiff lightweight steel frame yields a lively and comfortable ride.

50cm Size frameset. Suitable for 170-180cm. Ask me if you have sizing questions.

Reluctant to let it go as this bike was really fun both on tarmac and off road. Handling is light and nimble and accelerates really fast. This is because the bike is designed with compact road bike like geometry (quite close to the Giant TCR) but with tire clearance up to 40mm.

Had to let go of this bike frame because of lack of space. Would gladly have kept it for another built otherwise.

Frameset will come with the following:
a) Lightweight steel frame with triple-butted tubes, and internal cable routing.
b) Carbon Gravel adventure fork supporting fenders and cage. Fork is still substantially uncut so sizing would be easier.
c) Seatpost clamp with Marin 20mm offset seatpost
d) Thru axles
e) Spare derailleur hangers
