Trieu’s 650B gravel bike

Trieu came up to visit, so we were able to review his fit and plan out his build. His frame features a custom butted, round integrated seatmast with matching cap, a T47 BB shell to allow for fully internal rear hose routing, and internal routing for the Campy gear cables.

A matching steel fork and custom stem up front maintain the lines. I built Trieu two sets of wheels around Chris King R45 disc hubs – both feature Astral rims, with one set shod with 38mm tires, and the other 42mm knobby tires for more off-paved riding. The stealth ceramic coating on the rims is a good match for the King matte slate anodised finish.

There aren’t (yet!) too many options in 160mm cranks – the Lightning carbons have the added appeal of being made in the US. I was able to mix-and-match some chainrings to get a 30/48 set for a wide range of gears. The rest of the group is Campy Super Record with hydraulic disc brakes.

The frame and fork have all the mounts needed for full fenders – we used the 650B model from Portland Design Works, which were painted to match.

Trieu sourced a custom covered saddle and matching bartape from Mick at Busyman in Australia.

The paint is based on Porsche colors, applied by Colorworks. Final complete weight as shown is 20.1lbs.
