Recap: The Bikes of the 12 Days of Mosaic 2025

It’s become a Mosaic tradition. In December we showcase twelve standout builds on our Instagram feed as a way to revisit the prior year’s work. The bikes featured often include some of the most stunning and exotic customer builds, collaborations with our partners, eye-popping finishes, and sometimes, all-new models. Choosing the bikes is never easy. […]

Let’s Race Bikes! Join the Mosaic Factory Off Road Team.

Racing is a big part of the Mosaic story. Our bikes have seen National Championships wins, World Cup CX races, and our staff pins a number on for big events including Unbound Gravel, Mid South, Leadville and too many others to list. And for 2026, we’re inviting you to join us on the start line […]

Lost Bikes, UCI stickers and the Iconic Tabor World Cup CX

We caught up with Mosaic’s World Cup CX Racer Ben Frederick, whose busy 2025 season brought him to Boulder recently for some rides and racing. And then a whole lot of big stuff happened all at once. Last we heard you were racing the Boulder CX Cup in our own back yard. And then suddenly […]

The Three Big Advantages of a Made-to-Order Mosaic

For many riders, the idea of a custom bicycle can feel a little overwhelming. Do you really need a custom bike? Where do you even start? It can be a lot to take in—and we totally get it. That’s why we’ve spent nearly two decades refining the Mosaic Made-to-Order process, available on all Level 1 […]

Bike Check: Cumberland RT-Zero with Campy Super Record 13 Wireless

This build turns the dream-bike dial up to 13. Starting with one of the last framesets from our limited-run RT-Zero series, we paired Campagnolo’s brand-new (and many say best-ever) Super Record 13-speed wireless groupset with the superlight Partington R-Series MKII 39/44 Gold wheelset. Finished in a Cumberland Grey version of the RT-Zero-exclusive Shatter Camo Artist […]

Bike Check: Ben Frederick’s XT-1 CX Race Bike

Bike Check: Ben Frederick’s XT-1 Cyclocross Race Rig It’s November and #CrossIsDefinitelyHere, which means Mosaic Rider Ben Frederick is already busy chasing podiums in the biggest cyclocross races in the US. Fresh off last year’s successful Project Lead Lap Campaign in the European World Cup Cyclcocross circuit, Ben’s battle-tested race bikes are still good to […]

Mosaic x Builders for Builders 2025

Great trail networks don’t build themselves. They come from hard work, vision, and usually, a ton of support of the riding community. Each year, the Builders for Builders campaign brings together a select group of custom framebuilders to raise money for the Sierra Buttes Trail Stewardship, and in 2025 Mosaic is proud to again be […]

How It’s Made: Mosaic’s Ross Leopold Takes Us Behind the Scenes of the RT-Zero Development Process

We put a lot into our bikes. Even seemingly straightforward, batch-built Level 2 Mosaics require a ton of design, engineering and attention to detail, and that’s before tubes are cut and the torch is fired up. So you better believe that for the new Limited Edition RT-Zero, being the first model of our Zero Ops […]

BIKE CHECK: Mosaics of MADE 2025

MADE 2025 Show Bike #2: Mosaic MT-2 Trail Trout Mosaic CEO and Founder Aaron Barcheck has been known to strap a fly rod to his MT-2 hardtail and explore the rough high-country singletrack in a quest for native Browns, Brookies, and Cutthroats.

This is where we’ll push the boundaries of what we’re capable of, and what our bikes can do. We’ll test new materials, production methods and tools, and we’ll explore […]

Mosaic Artist Series: Form, Function, and Fine Art Finishwork

Raw titanium. Exquisite welds. Clean single‑color knockouts and signature fades in every hue imaginable. These are the hallmarks of Mosaic’s finish program, beloved by riders who appreciate understated elegance. But some riders look for more—a frame that feels like a rolling canvas, where bold patterns, complex paint techniques, and pure individualism come together. For them, […]

Batch Built by Mosaic: The Handmade Experience, Streamlined

It’s no surprise that at Mosaic, we build a lot of custom frames. But we’ve learned over the years that not every rider needs down-to-the-millimeter, full custom geometry to appreciate the lively, responsive ride feel of a Mosaic, without compromising on fit. Many riders fall into a relatively standard size matrix and just want a […]

Introducing: The Mosaic Factory Demo Program

Nothing rides like a Mosaic…it’s something you have to feel to understand. And if you’re looking to take a spin on one of our bespoke, handcrafted titanium dream bikes on the iconic Rocky Mountain roads and trails they were designed for, meet the people behind the brand and see where the handcrafted magic happens here […]

Stars, Stripes, and Gravel – A Patriotic GT-1 i45 for the 4th of July

While the Mosaic Finish Program typically centers around our curated Signature and Artist Series layouts—along with a massive array of stock and custom colors—every now and then, something truly one-off rolls through the paint booth. This stunning red, white, and blue GT-1 is one such example. Built for a sponsored Mosaic athlete, this stars-and-stripes gravel […]

BIKE CHECK: Mosaic GT-1 i45 x Velosmith

We teamed up with our friends at Velosmith and CeramicSpeed for a GT-1 i45 build that’s as fast as it is striking. This one features our Artist Series #7 Nebula paintwork, custom-finished down to the oversized pulley wheels—and a spec sheet that pushes performance to the edge of what a gravel bike can do. Naturally […]

It’s a finish line that represents something bigger than just a ride’s end. For the 200 or so riders who set off from Banff in June each […]

Kristen Legan Is Heading Back to the Hardest Race in Gravel – Unbound XL

Mosaic rider, PR pro at Dispatch, pro gravel racer, bike industry veteran—and winner of the 2023 Unbound XL—returns to Emporia for another go at one of gravel’s toughest tests: the 350-mile, 17,000-foot self-supported odyssey known as Unbound XL. Kristen! We’re a week out from Unbound XL. What’s on your mind right now? I’m really excited. […]

Flagstaff Week 2025 is HERE June 2-6!

Mosaic’s Flagstaff Week, a Boulder cycling tradition now in its 12th year, is upon us. Are you ready? Doesn’t matter. Flagstaff Week isn’t about being ready. It’s about way more than that. It’s a hard, good time that’s best explained by its creator, Mosaic Founder and CEO Aaron Barcheck, in his own words: The Setup […]

Time For a Change? Check Out the Mosaic Refinish Program.

A Mosaic titanium frame is built to last a lifetime—and ride better than anything else on the road or trail. But that presents a good problem: it’s hard to justify letting go of something this good. If you’re after that ‘new bike day’ feeling without adding to your quiver, the Mosaic Refinishing Program is the […]

BIKE CHECK: Adam Saban’s Drop-Bar Mosaic MT-1 Hardtail

Pro racer and cycling coach Adam Saban had an idea: a drop bar MTB that combines gravel bike fit and handling with MTB handling. But doing such a thing is more complicated than slapping a drop bar on a hardtail…as Adam soon learned. There’s a way to do it right, and Adam chose Mosaic to […]

Mosaic 1-Level Models – As Good As Bikes Get

Most bikes are built to fit a category. A 1-Level Mosaic is built to fit you in every way possible. Handcrafted in Boulder, Colorado, each frame starts with a blank slate and ends with a bike that rides, fits, and looks like no other—because it’s made specifically for your rides. Whether you’re chasing KOM’s on […]

An Interview with Artist David Cogdill and the Story Behind Nebula

To create any of our latest Artist Series finishes, you need more than a steady hand…you need vision, intuition, and a touch of chaos. Meet Mosaic’s own David Cogdill, the artist who turned stardust and stencils into Mosaic’s most otherworldly paint scheme yet—Nebula. In this Q&A, he shares how it all came together. Q: Where […]

Mosaic Batch Built Frames – the Best Value in Bespoke Titanium

When it comes to handbuilt bicycles, the sheer number of customization options—model, tubing, size, geometry and paint—can be overwhelming. But what if you could get a handmade titanium frame with proven geometry, dialed-in handling, and a simplified ordering process, all while saving time and money? That’s exactly why we created the Mosaic Batch Built program. […]

Level 1 vs. Level 2: Which One is Right for You?

Modern cycling is full of choices—road, mountain, gravel, all-road—each with its own appeal. On top of that, different price points and build levels add another layer of decision-making. In the Mosaic lineup, we offer our models in both a Level 1 and Level 2 option, each with its own rider-driven features and priorities. Let’s break […]

CX to Gravel: Ben Frederick Talks Bikes, Tactics and Transitioning Between Disciplines

Turns out, drop […]

RT-1 ITR: A Road Bike for Everything

Our back yard here in Boulder, Colorado is a paradise for road rides. France has smooth ribbons of tarmac winding through the Alps into the stratosphere. Kansas offers endless gravel roads stretching to the horizon. In Boulder, you get it all—seamlessly connected. Paved climbs turn to dirt descents, forgotten backroads lead to new adventures, and […]

New Artist Series #6 Colorway: Jack’s GT-1 i45 Scale in LAVA

If you were to gaze into the smoldering maw of an active volcano, it would look a lot like Jack’s GT-1 i45 in our latest Artist Series #6 colorway: Lava. With a metallic base coat of fiery orange and golden yellows accented by randomly applied Scale patterns of smoky grey and black, this bike is […]

Gravel vs. All Road: Choosing the Right Bike

It’s not just the dirt, it’s how you choose to ride it. In a few short years, riding drop bars with big tires on surfaces other than asphalt has gone from a fringe cycling discipline to the main event. Whether you’re scrolling through race results, bikepacking blogs, or your Strava feed, gravel is what’s happening. […]

Long Format Gravel Racing Season has wrapped up and the much-anticipated ‘Short Track Gravel’ season is already well underway. Some riders still call it cyclocross, we’re not sure why?
