With its ability to comfortably accommodate either 700c x 40mm or 27.5 x 2.1in tires, the Atalya Gravel is the frame for riders who want it all. Its elegant, clean lines are accentuated and strengthened by the addition of complex cast titanium elements, centered around a one-piece bottom bracket-chain stay system. The head tube is also cast, allowing for full internal cable routing compatible with both mechanical and electronic drivetrains. The signature cast titanium dropouts are compatible with flat-mount disc brakes and 12x142mm thru axles.

The Smoothest Ride, On Road and Off

Built to efficiently and comfortably handle long days in the saddle, the Atalaya doesn't confuse flex with compliance and draws on its designer's long experience with titanium to masterfully combine comfort with responsiveness.  Hidden and removable rack and fender mounts as well as provisions for mechanical and electronic drivetrains make for a versatile platform that that doesn’t look out of place however you use it.  And, like all J.Guillem frames, the Atalaya is backed by a 100 Years Warranty.  

This is a bicycle that doesn't just enable big rides: it inspires them.
