595g — Lightest Road Frame
Most optimized carbon layup ever. Lighter than the water bottle in your cage. Aethos redefined how we build bikes — Crux and Tarmac SL8 followed its lead.
Pure Riding Bliss
Impossibly responsive, supple, and sublime. Engineered to disappear beneath you. Ride 'in' the bike, not 'on' the bike.
New Fit for More Comfort
15mm increased stack takes pressure off hands, neck, and shoulders. 3mm lower BB height optimized for higher volume road tires and a more connected feel.
Rider First Engineered
Regardless of the bike's size, every rider gets the famed Aethos ride quality. Same transcendent feel across all six sizes.
47 Grams Saved
Saddle rail clamp (9g), bottom bracket shell (6g), brake mounts (2g), lightweight UDH (2g). Every detail obsessively optimized.

Passion drives us

At SpokeX Bike Co., bikes aren't just our business — they’re our way of life. As a rider-owned and operated shop, every decision we make comes from firsthand experience on the trail, at the race, and on the open road. We know what it’s like to chase a new line, push through the pain cave, and celebrate the ride — because we live it every day.
