Gravel racing tracks keep getting tougher, but the speed isn\u2019t going down, so Mosaic updates its flagship titanium gravel bike with a bigger clearance GT i55 series. Sure, bumping up to 55mm tire clearance seems pretty on point with current gravel racing trends. But doing it on a ti gravel race bike is a bit trickier, and it led to Mosaic developing their first 3D-printed titanium frame elements to fit big tires and big gears. Plus, Mosaic wasn\u2019t satisfied with current big clearance carbon forks, so they designed their own\u2026<\/p>\n

Mosaic\u2019s titanium GT began life as a gravel race bike when 40mm tires seemed like plenty for those who wanted to go fast. By 2019<\/a>, it had already been updated to 45mm clear, with its Enve forks topping out at 50mm. And its i45 evolution<\/a> a couple of years back combined that bigger clearance with integrated cable routing, and some killer paint jobs. They even built a special GT-X adventure iteration<\/a> that would fit 2.25\u2033 (57mm) tires.<\/p>\n
