Viathon announced the G.1, a gravel bike equipped with SRAM Red eTap AXS and HED Vanquish GP 4 wheels. While the brand is owned by Walmart, the bikes aren’t sold in-store – but can be pre-ordered now for direct shipment in 4-6 weeks.
2020 Viathon G.1 carbon gravel bike w/ SRAM Red eTap AXS
Viathon emerged as an interesting consumer-direct brand, under the ownership of Walmart. The new G.1 is their top-tier carbon gravel bike, with a loaded spec including Zipp cockpit, Fizik saddle, HED wheels, and SRAM Red electronic shifting. Frame weight is a claimed 1,010 grams for size 54, including derailleur hardware and bottle cage bolts.
The frame includes three water bottle mounts, along with mounting locations for a front rack, rear rack, and fenders.
The build uses a 1x chainring setup, but has compatibility for 2x. Asymmetric chain stays allow for up-to-46t single ring sizes, or 50/34 for 2x. A 40t ring comes stock.
Interestingly, Viathon chose a Red rear derailleur with 10-33 cassette size. While this should be sufficient for flat gravel riding, it would likely require an upgrade to a SRAM MTB rear derailleur and 10-50 cassette for serious hills.
Fizik handles seating duties, with the Aliante R3 138mm K:ium. Seat post diameter isn’t listed, but it appears to be a 27.2mm.
The top of the downtube has ports for internal cable routing, should you choose to run a mechanical drivetrain.
Five sizes are available for the G.1, all using 700c wheels. The frame may also be used with 650b wheels and tires at 2.1″ width or narrower.
Full specs can be found above, though complete bike weight is not listed at this time. The Viathon G.1 is available to preorder now for a list price of $6,998, including a two-year warranty from date of purchase for the original owner.
