Why We Love It
This is a blazing fast titanium gravel rig. The Mosaic GT-1 falls much closer to the performance road side of a gravel bike than a dedicated gravel bike. With a steeper head tube and short chain stays, the handling is sharp and snappy. However, a slightly longer wheelbase and lower bottom bracket provide stability and traction for chattery gravel roads. Mosaic provides enough space in the GT-1 for a forgiving 38mm tire. Additionally, a wisely-designed frame incorporates smaller tube shapes that provide a more compliant ride. All said, the Mosaic GT-1 is designed for the race-focused drop bar rider looking to push the gas pedal whether on pavement or gravel.
  • New Vittoria Terreno Mix tires for greater speed & higher performance on any terrain.
Master Mechanic’s Notes
  • Frame geometry was measured by hand and is therefore approximate.
  • Minor scratches on the fork legs.
  • Light scuff on the rear derailleur & crank arms.
  • Light wear and tear from cable rub, heel rub & chain.
