Mosaic GT-1 Custom Ti

[rollinslow]

Fully custom, titanium, Mosaic GT-1. Handmade in Boulder Colorado, internally routed with a small titanium guide tube welded inside the downtube. Max 45mm tires and has fender eyelets. And, of course, built in my home workshop. Build quality and flat mount so perfect it took 1 attempt to have perfect rotor alignment.

The goal of this bike was to do everything from chunky gravel to fast road, bad weather, and anyhting else I could think of. The emphasis was on ability to climb steep gradients (lots of 18-20%+ around here). Simplicity was important for ease of packing to fly with.

Beautifull bike, with a stunning paint job. The only thing I dislike is the 3T cranck, it doesn't look right on the bike.

that's funny, I actually love the Torno crank. I had wanted that for a long time due to that trapazoid shape and the insane lightweight.

Beautiful bike! Just one thing...is the Enve stem original? Usually a tell tale sign of fake stems is the bolt holes not being drilled all the way through.

Thanks!!!

Well, I assume Mosaic painted and filled it for cosmetic reasons to smooth the paint. If for the 8-9k USD for the frame/stem/sestpost (lost track of cost) that I paid when they made it for me they used a fake that would be quite the scandal for them haha. I have enough faith that a top tier builder would only use genuine parts.

Absolutely, I thought maybe you had bought the parts yourself from someone. Having been through the authentication process with Enve I was told about a few obvious things to look out for.

The stem looks so much better with the holes plugged up.

Wow, what a build! Recently I've really been loving the look of a metal bike with colormatched stem. The lines of the Enve stem in particular are quite nice.

Hahah yeah. you certainly need to do some good convincing! My wife also has a Mosaic, and a friend has an RT-2 based on my positive experience with Mosaic. Everyone is happy so I can only say positive things about Mosaic.
