What it does well: Alchemy is a boutique builder from Colorado’s Front Range. They bill the Aithon as a Carbon Gravel Racer, and that depiction is pretty much spot on. Our bike was built up with ENVE carbon rims and Ultegra road parts. We found it comfortable and pliant on and off dirt roads—and fast. The carbon seems to eat up vibrations and small hits and lets you stay seated while hammering. There’s also a beauty factor here—especially in the wishbone shaped rear triangle and rich, deep finish.
What it does poorly: The Aithon—the name comes from Greek myth—would be our choice for an actual gravel race or whenever the local group ride opts for a day of dirt, but like the BMC, it’s no detuned cyclocross bike. We’d keep it off the ragged doubletrack.
So who’s it for? If you had two sets of wheels (one with skinny tires and one with some chubs), the Aithon could go from bruising gran fondos and centuries to California style gravel races. 3.8 lbs.
