Shimano Showcases Ten Custom Bikes With Stunning Silver GRX Limited

At this year’s Unbound, Shimano will be unveiling its new GRX Limited group, which offers silver components for drop bar and flat bar GRX kits. It’s been a while since a big brand offered up a brand new, high-end group in silver, so as you might have guessed, we’re stoked to share this news with you.

To commemorate this special moment, Shimano pinged ten framebuilders to showcase this new kit, so let’s look at each of the builders’ creations below…

Mosaic Drops the Mic with the New 29×2.25 GT-X Gravel and Adventure Bikes

Mosaic has added two new frameset models to their G-Series lineup of gravel and adventure bikes. The GT-1X and GT-2X are two new Mosaic framesets for riders seeking a big tire, off-road capable titanium adventure bike. Both GT-X frames are designed around a 29×2.25 tire, a gravel-specific or MTB drivetrain, and a geometry that incorporates a longer top tube and shorter stem, allowing the rider to set up their GT-X in a drop bar or flat bar configuration. The addition of optional frame bag and accessory mounts, as well as rack and fender mounts, make the GT-X capable of all-season, all-terrain exploration.

The GT-1X utilizes Mosaic’s top-of-the-line, double-butted titanium tubeset. Custom geometry and a rider-specific tubeset are included as “standard” options on GT-1X, making it a truly custom build. The GT-1X is offered in the rider’s choice of Mosaic Paint Layout or the Mosaic Factory Finish.

The GT-2X utilizes Mosaic’s simpler straight gauge titanium tubeset. The GT-2X is offered in 7 stock sizes from S-XXL, with custom geometry available as an upgrade. The GT-2X is finished in Mosaic’s standard raw finish, with available upgrade options to a Mosaic Paint Layout or the Mosaic Factory Finish.

Every GT-X adventure bike is built to order and finished in Mosaic’s Boulder, Colorado facility. Orders can be placed through a Mosaic dealer, and frames carry a 12 week lead time from the date that the details are confirmed, the order is signed off and put into the build queue.

With this catalog of talent at their fingertips, they decided to have an Open House to celebrate not only their factory and offices in Ogden, Utah but the frame builders who choose ENVE to build out their complete bikes.

2017 NAHBS: Mosaic Fendered Road with Dura Ace

For 2017, Mosaic has launched a new paint program with multiple tiers of finish offerings. Customers can now choose between 30 colors and 6 layouts, making their bike unique. The paint is executed by the newly-acquired Spectrum, which Mosaic owner Aaron Barcheck purchased last year. While the Spectrum label is under Aaron’s control, it is still a separate entity from Mosaic.

This year at NAHBS, Aaron brought his fendered road bike with Dura Ace Di2. By utilizing ENVE’s GRD fork and fender attachment, this bike will be good on the Colorado roads throughout the spring.

Mosaic Goes Full March Madness

Mosaic Goes Full March Madness

To be honest, I’m not enough of a “ball sport” fan to really know what March Madness is, yet I appreciate the execution here. Then again, it is Mosaic, a framebuilder known for their precision. Here’s what’s going on with these two bikes!

“The timing of the NAHBS show happened to coincide with the start of the NCAA March Madness tournament. Paul Keodprom from Blacksmith Cycle in Toronto and his bud Eryn Stott made the drive down to Charlotte to hang with the crew from Mosaic Bespoke Bicycles, which organically turned into the production of these collegiate themed Mosaic RS­2 framesets. The two schools might not have met each other in this year’s tournament, but it’s a Syracuse vs. Michigan showdown whenever these two bikes hit the road.”

2016 NAHBS: Mint Mosaic RS-1 Road

Aaron Barcheck and his team at Mosaic never cease to amaze and impress at NAHBS. For them, they don’t need to go over the top on show bikes because their work is just that: over the top. It’s the “every bike is a show bike” mentality. This minty green RS-1 road bike, with painted to match Silca frame pump is for Velo Smith in Chicago.

Brooke’s Mosaic XT1 Disc ‘Cross

Brooke’s Mosaic XT1 Disc ‘Cross

Brooke is an experienced cyclist and when the time came to order a custom ‘cross bike for not only racing but everyday dirt riding in San Francisco, she contacted Aaron and his team at Mosaic Cycles to get her fit on a custom XT1 disc ‘cross.

You see, for someone with Brooke’s proportions, it’s hard to fit on a stock bike from many of the big-named companies, so a custom bike which would be tailored to her body seemed like an obvious choice. She didn’t just want to fit on a bike, she wanted the bike to fit her. The end result was a confidence inspiring feel without toe overlap and enough standover to make unexpected dismounts easy. Key build details are the SRAM Red 165mm cranks (since Force CX1 doesn’t come in that length, that new and fancy TRP thru-axle ‘cross fork and some great I9 to Pacenti wheels.

When Brooke and her friend Tessa were in Los Angeles for a wedding, I met up with them to go on a quick ride and couldn’t resist documenting this bike, but bringing my camera along for a little sunset ride…

One on One with the Mosaic GS1 Disc All-Road

One on One with the Mosaic GS1 Disc All-Road

Remember this one? From NAHBS? It was one of my favorites in the show. Everything about it just looked right. First impressions are everything you see and these days, with the whole bigger is better mentality about tire clearances, it was nice to see something embrace a modest tire so elegantly.

Mosaic‘s GS1 disc all-road bike is a custom steel or titanium frameset, offered by the Colorado-based frame builders.

Let me reiterate that: this is not a production model with stock sizing. It’s made with 100% custom geometry. A custom geometry ensures this bike will fit you like a tailored suit.

The GS1 is a road bike with disc brakes and room for around a 38mm tire. It has a road bottom-bracket drop (72.5mm) and a slightly slacker head tube than your average road frame (72.5º). Side note: I like how those two numbers match up so perfectly. The 420mm stays and 1033.5mm wheelbase can be best interpreted as smooth sailin’ down your favorite road, be it dirt or sealed.

Meet Your Maker with Above Category and Aaron Barchek of Mosaic

People have a lot of misconceptions about the frame building process and even the builders themselves, which is why I value a good interview. Above Category conducted one such interview with Aaron Barchek of Mosaic Cycles on their blog and it’s worth the read.

If you’d like to meet Aaron yourself, he will be visiting Above Category in early May. There will be a group ride on the 9th of May at 8.15am. More information to follow on AC in ‘The Broomwagon’ and their Facebook.

The 2015 Rouge Roubaix Builder Challenge: Mosaic

The 2015 Rouge Roubaix Builder Challenge: Mosaic

For Boulder, Colorado’s Mosaic Cycles, the Rouge Roubaix Builder Challenge was the perfect epilogue for the 2015 North American Handmade Bicycle Show. Many of the bikes featured at NAHBS found their way to the RRBC and rightfully so. Why build something if it’s not meant to be ridden… Into. The. Ground.

The Mosaic line is divided into a number of specific uses. There’s a binomial nomenclature of sorts, or a key, to deciphering what bike is made for what and out of what material. Each member from Team Mosaic chose a bike that best fit their riding style. Be it steel or titanium, disc or rim brake, each of these bikes were built specifically to reflect their own preference.

As for the application process and the overall team, Aaron selected Boulder shredmeister Brandon Newcomer on an RS-1 (road steel), Velo Magazine correspondent Spencer Powlison on an RS-1 and finally, Derek Yarra, the RRBC winner on an RT-1d (road titanium disc), which matches Aaron’s own bike selection.

Derek and Aaron’s bikes will fit a fat, plump tire and because titanium is a naturally forgiving material, they offered a bit of compliance during the 100 mile race. If you’d like a further break down on each of these riders and their bikes, head to Mosaic to read up.

… there’s more coming soon on what else Mosaic brought with them: a wild card group of ladies…

As for Derek’s RT-1d, it’s built with Shimano Ultegra Di2, R685 hydraulic road disc brakes, Shimano Pro Vibe cockpit, and Shimano RX80 tubeless-ready wheels. My personal favorite detail: the Shimano mtb pedals!

Team Mosaic would like to thank Shimano, q36.5 Kits and Rothera Caps.
