It’s not a model for everyone, but one that is growing in popularity. Today, Viathon launched as a new direct-to-consumer carbon bike company. Interestingly, a quick trademark search shows that Viathon is backed by Wal-Mart, and the Arkansas company holds the trademarks to the Viathon brand name.
Viathon’s staff is made up of bike industry veterans, and the company has partnered with Kevin Quan Studios for its design and engineering.
The company’s launch includes three bikes: the G1, R1 and M1 for, aptly, gravel, road and mountain biking, respectively.
We take a first look at the Viathon G1 available in three different builds ahead of the 2019 Sea Otter Classic trade show.

Viathon G1 Gravel Bike
The G1 gravel bike has a carbon frame that boasts a claimed sub-1,000g weight, and a carbon gravel fork that is flat mount disc. The frame includes an oversized bottom bracket for increased stiffness and internal cable routing throughout.

Similar to most gravel bikes these days, the G1 has rear rack and fender mounts and mounts for bags or a rack on the fork.
The geometry on the G1 is similar to an all-road bike, with a 72-degree head tube angle on a 56cm frame. The BB drop is 6.9cm, the chainstays are 42.5cm long and the wheelbase comes in at 102.4cm. The stack on the 56cm frame is 58.2cm and the reach is 38.8cm.
Like other gravel bikes we have seen, the Viathon G1 uses a dropped drive-side chainstay for more tire clearance. Viathon claims clearance for 700c x 51mm and 650b x 53mm tires.

The G1 comes in three builds. The G1 Force is $3,550, the G1 Ultegra is $3,300 and the G1 105 is $2,300. The frameset alone costs $2,000.

The brakes on all three models are hydraulic disc.
Each build comes with HED Ardennes LT alloy tubeless clinchers that have a claimed weight of 1,549g. The bikes ship with 700c x 35mm Continental CycloX King tires, which is a curious choice since the tires have been discontinued and are a folding bead clincher.
