Mosaic RT-1 Limited Edition

Top-flight titanium race bike from Colorado company

Based out of Colorado, USA, Mosaic are a brand that specialise in hand-crafting metal bikes. They’ve been making them since 2009 when founder Aaron Barcheck left Dean Titanium Bicycles to form his own company.

Mosaic make bikes from two materials: steel and titanium. They also make road, mountain and ‘cross bikes and so have a wealth of experience and versatility with their two chosen mediums.

This one was built for our shoot by Prestige Cycles down in Brighton, who also happen to be the UK source for Mosaic bikes. And, as you can see, they’ve done a pretty amazing job.

The other thing is Mosaic don’t make off-the-peg bikes, they tailor each frame to the specific needs of a rider. That means you go through a fit before ordering, and the measurements – over the course of time – are changed into a beautiful bike frame.

The Mosaic RT-1 Limited Edition is the brand’s top flight titanium race bike. It’s built around a lightweight double-butted titanium frame.

That frame is paired to Enve’s Road 2.0 fork, a 350g piece of carbon beauty that retails at a cool £350, that’s £1 for each gram. Until you cut the steerer tube, of course.

Of course, being a custom bike, you can get your hands on one of these built up pretty much however you fancy. This one was built for our shoot by Prestige Cycles down in Brighton, who also happen to be the UK source for Mosaic bikes. And, as you can see, they’ve done a pretty amazing job.

Our bike was equipped with a gorgeous brushed titanium seatpost that perfectly matched the frame.

Groupset is Campagnolo’s Athena EPS, which works so nicely because the RT-1 frame is internally routed for electronic groupsets and, as it happens, has internal routing for both brake and gear shifting.

When you order a Mosaic, you can have your choice of bottom bracket, making it ideal for Campagnolo who offer setups that fit with the classic BSA style threaded bottom brackets as well as (comparatively) newer press fit internal bearings. If you’re after even more options, you can also buy a disc brake ready version of the frameset.

Seatpost on here is 30.9mm, rather than the currently popular skinny 27.2mm, but seeing as titanium is a more forgiving material than carbon that likely won’t cause too much discomfort out on the road. The shoot bike was equipped with a gorgeous brushed titanium seatpost that perfectly matched the frame.

Up front, the 3T Aeronova bars are a seriously fast looking piece of finishing kit, and the black of the bars and red Lizard Skins bar tape match up wonderfully with the red and black Fizik Arione saddle. Oh, and if that’s not enough the build rolls on a set of Campagnolo Bora Ultra 50 tubular wheels.

However, if you want this particular bike, it’s not going to be easy to find one. Mosaic made five of these special edition framesets to raise awareness for prostate cancer – hence the ‘Men United’ laser etched into the top tube and the pictures that adorn the top and down tubes. The plan is to sell off the five and £1,000 from each sale will go to charity. Needless to say, they’re not going to be cheap.
