Mistakes happen...

Due to a fixturing issue, some of our latest batch of frames came through with one set of not-to-spec bottle cage bosses per bike.  Sure, they'll work with a slotted cage like Silca's Sicuro- but they're not right.  We're scrambling to get replacements welded- but if you're willing to wait a few weeks, we'll repay you with $500 off.

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, drawing on its designer's long experience with titanium to masterfully combine comfort with responsiveness. Its elegant, clean lines are accentuated and strengthened by the addition of complex cast titanium elements, centered around a single-piece bottom bracket & chainstay system. The custom head tube cleanly integrates cable routing for both mechanical and electronic drivetrains.

J.Guillem signature cast titanium dropouts are compatible with flat-mount disc brakes and 12x142mm thru axles. Full rack and fender mounts and clearance for up to 700c x 44mm or 27.5 x 2.1in tires 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-Year Warranty.

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

FAQs

Do you offer custom builds on your frames?

Absolutely! Our stock builds are just where we feel like we can offer the best balance of price and performance. But we all have our fit, color, or brand preferences and we love tailoring bicycles to their new owners' needs. Contact us to learn more.

How do I buy one?

Well, you’re in the right place! We primarily sell J.Guillem frames direct to consumers. Part of that’s our location: not everyone is able to travel to New Mexico. We also know that not every shop can be expected to carry smaller brands- if you want something unique and special chances are it won’t be in stock around the corner.

We do love bike shops, though! If you are a bike shop or have one you’d like to work with on your build, please contact us and we’ll work hard to make it happen.

My size or option is out of stock!

Don't sweat! Drop us a line and we'll get what you're looking for or find an appropriate substitution. With the exception of wheels, most things are one to three days away.

How are bikes built and shipped?

We work with a local pro shop on all of our complete bike builds. They have loads of experience with frame-up builds and see even the rarest drivetrains and most niche parts on a regular basis. This way you can be confident that your bicycle will be built by a professional mechanic and test ridden before being packed and shipped via FedEx.

How long will it take?

Because each build is tailored to you, in-stock sizes and options take two to three business days to build.

Do you have a warranty?

A J.Guillem frame is built to provide performance that lasts and is backed by a 100-year warranty against defects in materials and workmanship.
