Limited Edition Titanium Gravel Magic
As longtime devotees of Aaron and Mosaic’s passionate design and small-batch build process, we’ve been looking for a chance to collaborate with these Boulder-based titanium and steel architects to craft something totally unique to the market – and the opportunity finally presented itself. In addition, we brought TPC founder, Nick Martin, and The Radavist founder, John Watson, along for this once-in-a-lifetime ride.
The results of this creative and design alliance are the stunning TPC x Mosaic GT-2 45, GT-2 45 Di2 and GT-2 X. Conceived and built as limited-editions exclusive to TPC, once these bikes are sold, no others will be made. From the ground up, they’re like nothing else on the trail.
The first thing that catches the eye is the subtly exceptional paint scheme in either Desert Tan or Nebula Green. Inspired by Nick and John’s love of classic Toyota Land Cruisers, the paint replicates the colors made famous by those iconic 1970’s 4x4’s.
The GT-2 45 Di2 is a titanium gravel stallion designed to conquer the harshest roads – and ask for more. The 45mm tires and handbuilt titanium frame create a smooth ride you may not expect from such a burly bike. With Shimano GRX Di2 electronic shifting, Industry Nine UL 250 carbon wheels and an ENVE cockpit, the GT-2 45 Di2 reflects a top-shelf build that delivers all-day on the trail. Whether you're in the lottery for Unbound Gravel or planning epic, multi-day adventures along the Aquarius Trail Hut system, the GT-2 45 Di2 will be your trusty sidekick.
The TPC x Mosaic GT-2 45, GT-2 45 Di2 and GT-2 X fuse enduring aesthetics, modern efficiency and the comfort of titanium in a gravel bike that’s more than capable of tackling any route – and turning heads.
Go inside the build and see how these incredible bikes were conceived, created and ridden. And, watch a conversation
with TPC founder, Nick Martin, and Mosaic founder, Aaron Barcheck, as they discuss the bikes, Mosaic’s beginnings and the ties that bind these industry leaders.
And if you’re ready to ride a rare build that can hold its own on the trail, find your TPC x Mosaic collaboration model and start planning your next adventure.
