Featuring 1x Shimano GRX shifting, ZIPP Service Course SL cockpit, and Mercury G1C carbon disc brake wheels, the carbon gravel bike slots in between the top spec SRAM Red eTap AXS model at $6,998 and the SRAM Force model at $3,498.
The 1,010g frame (size 54cm) allows tire clearance for up to 40c tires on 700c or 2.1” on 650B/27.5”. The asymmetric chainstays can accommodate a 46t 1x, or a 50/34T traditional crank-chainring configuration.
Other features include three bottle cage mounts, front and rear rack mounts, and fender mounts. Available in 52cm, 54cm, 56cm, 58cm, and 60cm, and the bike comes in black/copper or black/silver.
The Viathon G.1 is also available with SRAM Red eTap AXS ($6,998), or SRAM Force ($3,498) component groups. A frame-only option ($1,498) is also available.
Full disclosure, I’m riding/racing a G.1 Force this year (which I purchased) and so far I’m loving it. Most notably, the threaded bottom bracket is a godsend, creaky frames be damned.
