Mosaic

Mosaic is a boutique manufacturer of beautiful Steel and Titanium frame sets, based out of Boulder, Colorado. Their RT-1 redefined what one can expect from a Titanium bicycle as it combined stiffness and explosiveness once found only in the harshest carbon frames, with a subtlety and liveliness that only metal can provide. The RT-1 is available in full custom geometry and paint schemes and the understated raw Ti finishes are a thing of beauty. Their mastery of steel is unrivalled and their RS-1 is quite possibly the finest steel bike available.
