Mosaic MT

Aug 08, 2023

Mosaic’s booth at the MADE handmade bike show over the weekend had a number of new bikes to ogle. Included in the lineup was this updated MT-1 made-to-order titanium hardtail. Beyond their revamped mountain bike, the GT-1 45 gravel bike got a UDH upgrade, and the newly integrated RT-1 ITR showcased a new colorful Artist Series paint job option. Additionally, all bikes can now Colorshift, too…

Just under a year ago, Mosaic updated their more affordable batch-built MT-2 ti hardtail with modern geo and bigger tires. Now, they are back with a similar update to their lighter, made-or-order flagship MT-1 titanium XC hardtail. Also designed for 120mm forks, Mosaic describes the MT-1 as that perfect blend of “modern XC geometry with a hint of rowdy trail riding“. What’s more, this MT-1 is their lighter double-butted ti mountain bike with a bit more of a race-ready spirit.

First up, the new Mosaic MT-1 gets the exact same stock geometry update as the MT-2 did, for improved modern XC-into-Trail capabilities. But every MT-1 is handbuilt-to-order in Boulder, Colorado. So you can also customize that geometry if you need to tweak your fit or want to go faster or get more rowdy.

What else sets it apart is the custom lightweight double-butted T3A/2.5V titanium tubeset Mosaic uses to handbuild the MT-1. The new MT-1 also gets a UDH upgrade to bolt-on the latest SRAM T-Type transmissions.

The MT-1 is designed as a light race bike, so Mosaic designed it around 29 x 2.4″ tires. Yet, there’s still clearance for up to 2.6″ tires if needed. The frame is Boost-spaced, gets a 73mm threaded bottom bracket, 30.9mm seatpost, and comes with a tapered Chris King Inset 7 headset.

The updated Mosaic MT-1 sells for $6600 for the titanium frameset, with a 6-week leadtime. It comes in 4 stock sizes (S-XL), or you can get custom Rider Specific Geometry at no extra cost, as well. Pick from your choice of standard Mosaic paint layouts in your colors of choice, raw ti, or go for one of Mosaic’s premium Factory Finishes, all included in the standard pricing. Routing is up to you, depending if you need/want internal cabling in the downtube or opt for more of a pared-back wireless or simpler external setup.

Complete bike builds are always possible, too. This XO Transmission build with a custom-painted (Beautiful Chaos) Fox 34 SC Factory fork & Enve M525 carbon wheels would sell for $13,575.

Mosaic’s top-tier GT-1 45 gravel bike also gets an update, moving to the UDH standard for improved drivetrain compatibility or ease of derailleur hanger replacement. The GT-1 45 is Mosaic’s premium level-1 custom titanium gravel bike, designed for 42-45mm tires. Pick a GT-2 for more affordability, GT X series for bigger off-road tires, or a GT AR for faster all-road gravel builds.

But it seems like only the custom GT-1 gets a UDH for now, although you can also still get an old-style replaceable hanger if you want for some reason. Although, we’d guess all of the level-1 ti bikes should have the UDH option soon.

Built together with their Chicago dealer shop Velosmith, Mosaic’s MADE show bike gets more than just a UDH with an Eagle mullet transmission. Mosaic finished it in a new Artist Series paint job named ‘Beautiful Chaos’.

This new level-1 finish option mixes crisply masked lines with splatter drip effect paint details. Put that all over a fade paintjob, customizable in your fav color palette.

Another updated bike with killer custom paint is the recently integrated Mosaic RT-1 ITR road bike. The new ITR moniker means Integrated Thick Road. Thus, it combines mega 35mm slick tire clearance with fully hidden internal cable routing.

The custom double-butted ti RT-1 ITR features Enve’s new Integrated Road fork/bar/stem combo. Furthermore, there’s that lust-worthy Chris King classically-styled Aeroset headset, plus new Mosaic road chainstays

This RT-1 ITR show bike also sports a new Artist Series finish.

Here, it is ‘Prismatica’, e.g. a nod to MADE’s Portland neighbor Chris King. Hence, they decorate it with small colorful bubbles, bumble bees, and crowns in a rainbow of splatters.

Of course, Mosaic also includes an appropriately colorful set of purple Chris King components to round out its custom build.

Lastly, every level-1 Mosaic can now get a Colorshift paint job, too. At MADE, Mosaic painted 6 GT-1 AR all-road gravel bikes in these new 6 Colorshift colors from their Finishwork lineup. Thus, now pick from the color-changing chameleon look that best suits your custom style.
