Bikes of MADE: Nightshift Scale RT-1 ITR

Show Bike #3, and another addition to the Scale lineup… Nightshift. Artist Series colorways tend to be loud and attention grabbing so for this one, we flipped the script. From afar, it looks like a black bike. Get closer though, and you might find yourself continuing to find new details the longer you stare. Inspiration: […]

Bikes of MADE: Mark’s Silverstone GT-1 iAR

For our second MADE Show bike, fast cars provided the necessary inspriration to put together a blazing fast GT-1 iAR. In the world of fast cars, there’s nowhere better to look than Formula One… As everyone has their loyalties, the Mercedes AMG F1 color palette kicked things off. Inspiration: The Mercedes AMG Formula 1 car, […]

Bikes of MADE: Liz Barcheck’s UltraViolet Scale RT-1 ITR

Show bikes are hard. We usually have way too many ideas and the challenge is how to land on the right ones and then pull everything together in time. For this year’s Made Show Bike lineup we wanted to showcase the depth of options available in our Artist Series, starting with my partner Liz’s RT-1 […]

Adventure Journal – Breaking in my new GT-1 i45

The season is well underway and recently I received my brand new Mosaic GT-1 i45 gravel bike. Since the folks at Above Category built up the bike and friend/photographer Jim Merithew shot NewBikeDay photos, this bike and I have been on some serious adventures. It’s all been a bit of a blur recently, springing from […]

In Partnership With The Small Monsters Project

As Ben puts it, “Hard Things Are Hard… And It’s Okay”. Ben Frederick takes those words to heart, and that concept sits at the core of The Small Monsters Project Foundation – a non-profit organization whose mission is to reduce the stigma around mental health challenges and to provide education and resources around concussion. Since […]

Photo Journal: A Dang Good Time in The Mid South

Last weekend, the Mosaic crew loaded up the van and pointed it East towards the red dirt roads of Stillwater, Oklahoma. We had ourselves a blast, saw old friends, made new ones, drank some beers, ate too much pizza… You know the drill. It was the Mid South Gravel weekend, and here’s how it went […]

SRAM UDH & Transmission Compatibility is here.

If you’ve been paying attention to the mountain bike world, then you likely know that just a few short months ago SRAM not-so-quietly launched their latest drivetrain innovation – Transmission. The Transmission (T-Type) drivetrain is anchored around one absolutely critical feature – Universal Derailleur Hanger (UDH) compatibility. The T-Type derailleur ditches the conventional derailleur hanger […]

Adventure Journal : An Unforgettable Year Aboard My Trusty Mosaic GT-1 iAR

At the end of 2022, I had numerous meetings and conversations with Mark and Aaron at Mosaic about the upcoming year. We were all thrilled to be working together, planning out a busy year, and looking forward to formalizing a very unique and special collaboration. After nailing down the nuts and bolts of our partnership […]

Adventure Journal: Allan Shaw’s 6 months on a GT-2X

On January 9th this year I stopped in at Vatio bike shop in Mexico City to pick up one of the most exciting deliveries I have ever received. My brand new Mosaic GT-2X with a custom build and paint job was finally here, and it was even more beautiful than I was expecting. The main […]

GT-1 or GT-2?

Gravel Decisions You’ve decided to embrace the gravel cycling trend, and now it’s time to figure out which bike is right for you. Our GT-1 and GT-2 framesets may share some geometry characteristics, but underneath, they’re very different machines. Both framesets are available in two different configurations, Allroad and Gravel 45, which if you’re curious […]

Three Reasons Why You Want a Made to Order Frame

If you want a bike that’s completely perfect for you, something that’s one of a kind, it’s time to talk about Made to Order Mosaic frames. There are a host of reasons why people opt for a full-custom build. The great thing about a Made to Order frame is that it will do exactly what […]

Land Cruising : A collaboration with The Pro’s Closet & The Radavist.

When we were approached by The Pro’s Closet and The Radavist with an idea for a brand collaboration, whilst we were extremely excited about the prospect of working with such a talented team, we’ll be totally honest, at first we were a little hesitant and unsure what to say… At first glance, it seems like […]

Adventure Journal: All Roads in Colombia

The Idea: We’ve talked about riding bikes in Colombia for years, its been quickly creeping its way up to the top of our list of destinations to visit and rid. With the feeling COVID is mostly in the rearview mirror, this seemed like the time to do the things we’ve always talked about doing. Our […]

Batch Built. MT-2’s and GT-2 45’s delivered in 2-4 weeks.

Handbuilt bikes aren’t built with the press of a button. A lengthy lead time is a commonality in the world of handbuilt products, whether that be bicycles or otherwise. For a completely custom, “1-of-1” type product, a long lead time is entirely justifiable because if finished product will be unlike any other that came before […]

RT-1 ITR: Built For Any Road

Boulder, Colorado is the ultimate place for drop-bar bike riding … But we’re biased. Sure, some places have pure paved riding that’s a little better, with buttery smooth switchbacks and narrow roads. And we’ll concede that there are probably better locales for gravel riding — more remote, rugged, and vast. However, our hometown has literally […]

Unbound Gravel Bike Check – Mark’s GT-1 45

It’s Unbound Gravel time. Take a look at what we’re riding… Unbound Gravel, the event in Emporia, Kansas this upcoming weekend almost needs no introduction. Just in case this is the first you’ve heard of it, Unbound Gravel is a 200-mile dirt road/gravel race throughout the Flint Hills surrounding Emporia, Kansas. It has widely become […]

Adventure Journal – The Denali Highway

The Denali Highway is often referred to as one of the loneliest roads in America. A crafted blend of oversized internally double butted and thin walled straight gauge tubes make a responsive handling characteristic without losing the quality ride titanium frames are known for while keeping the weight as low as possible. As our flagship […]

Mosaic Cycles signs Brennan Wertz

Remember the time back in ’21 when we built a GT-1 45 for a then up-and-coming bike racer eager to try his hand at the highest level of gravel racing? Well, just to set the stage anyway, that bike racer is Brennan Wertz. We built Brennan that bike, he rode it literally once, and then […]

GT-1 45 & GT-2 45 Chainline Update

GT-1 45 & GT-2 45 : Gravel Chainline Our most popular framesets, the GT-1 45 and GT-2 45 are getting a little update. Starting today, by default, all GT-1 45 and GT-2 45’s will be built specifically for use with a gravel groupset/chainline. These groupsets include Shimano GRX, SRAM Force Wide, and all SRAM XPLR […]

Bike Checks – Our GT-X adventure bikes for The Denali Highway.

If adventure bikes need a thorough shakedown, then where better to put three prototype bikes to the test than the Denali Highway?! The Denali Highway is a 135 mile stretch of unpaved and minimally maintained road, southeast of Denali National Park in central Alaska between Cantwell and Paxon. It’s an area that words don’t do […]

How a Mosaic Batch Built Frame Is Made

Take two Mosaic frames — one Batch Built, one Made to Order — and look at them side by side. Can you tell the difference? Probably not, and that is because our Batch Built frames go through the same made-in-USA process as any Mosaic bike that rolls out of our Boulder, Colorado shop. Here’s how […]

Is a Mosaic Batch Built Frame Right For You?

Reach, stack, head tube angle, bottom bracket drop, paint, finish … You have tons of options when you order a handbuilt bike. But a while back, we started to realize that some riders don’t need a Made to Order Mosaic to get the perfect bike for their favorite rides. So, we created the Batch Built […]

Behind The Bike // Sheldon’s RCCLA RT-1d // The Cub House

Rapha Inspired, Cub House Built Since we’re unable to visit our friends and customers in person for the foreseeable future, we’re starting a new series of blog posts to stay connected and build upon the relationships we have with our shops, our customers, and their bikes.

Prismatica: The Artist Series

In preparation for Chris King Precision Components‘ Annual Open House, the paint team was given a brief for an RS-1d frameset heading their way: This bike needs to be colorful, highlight the new Chris King headset color and be uniquely Mosaic. A week later, the painters had a few test pieces in the works after […]

Gravel vs. Allroad – What’s the difference?!

It’s not just the dirt. So, you’ve probably picked up on a bit of an emerging and flourishing trend in cycling… Gravel. It seems to be all we’re talking about these days. However, I think there’s still a level of uncertainty around gravel for many of us that only years ago would have labeled ourselves […]

Downcountry Hardtail? Whatever You Call it, MT-2 Does It

It seems silly that the bike industry just recently realized that cross-country bikes would be more fun with just a tad more travel and capable geometry. Also, it is odd to take a classic hardtail and water it down with comically slack angles and a too-long suspension fork. Our MT-2 mountain bike is everything a […]

Adventure Journal: Allan Shaw’s Atlas Mountain Race – Embracing Cold and Dark in North Africa

I’m walking my bike up the last few steep switchbacks on the ridge of a tall mountainscape, bathed in the full moon, catching and reflecting the snow on the hillside. Gazing down the mountain on a sea of bike lights of a hundred other cyclists behind me, slowly making the same journey up the valley. […]

Short Track Gravel… Wait, what?
