Mosaic GT-1 AR

A Race Ready High Performance Bike with Many Bespoke Options for Ultimate Customization
On the spectrum of gravel bikes, the GT-1 is closer to a road bike than an adventure bike. The geometry lands between traditional road and off-road frame specs with short chainstay length, steep front head angle, oversized head tube, and carbon fork. This provides a snappy feel on the road while low bottom brackets, a slightly longer wheelbase, and tire size make for stable off-road handling. It is built on a flat mount disc brake platform for all-terrain stopping force and also creates clearance for a 38c tire. The 3/2.5 double butted tubeset can take the abuse of riding all year in any climate without worry of corrosion or denting with minimal care. Smaller diameter tubes are hand selected according to rider weight, providing a more compliant ride. In contrast to the oversized and responsive X or R-Series tube selection that can be oriented towards race performance, the GT-1 aims at a different category of performance: one of comfort, longevity, and functionality. Optional fender and rack mounts make the GT-1 a perfect bike for year round riding.

All of our bike prices include pro-assembly.
One of our highly experienced pro-bike specialist mechanics will build your bike, then test ride it in the parking lot to verify everything works flawlessly. We will then remove the rear wheel, seat post, and front stem plate for shipping. Your bike will be packed for shipment in a manner that fully eliminates any possibility of arriving to you in less than perfect condition. Once you have your new bike, simply install the front wheel, slide in the seat-post/seat, and attach the stem front plate. You will be ready to ride or race in minutes.
The selection of the correct size frame (and stem, bars, cranks, etc.) is a crucial aspect of the road-bike buying experience.
We will contact you once you have placed your order to discuss and verify the sizes of each item that you need. Once you receive your new bike, ride it for a week or two and verify that you are comfortable with your chosen stem length, bar width, and crank length. If not, you may exchange any of these items for another size, as long as they are returned in as-new condition. (As-new, meaning: unblemished in any way other than bar-tape residue, pedal installation marks on the cranks, etc.) We will then rush you the size that you desire of the item, and sell the returned item as a test-ridden item at our retail store. If desired, we will provide a full comprehensive bike fitting free with any bike purchase. We work with the sizing system from of our favorite full-custom frame builder, Moots. Just go to moots.com and print out their highly comprehensive sizing questionnaire (with very detailed, easy-to-use instructions and pictures.) You will then be contacted by one of our in-house sizing specialists. We welcome all of your questions on any and all aspects of the sizing process when you are purchasing a frame or bike from us!
