Italian tubing and component maker Columbus has an all-new Trittico system of carbon bars, stem & fork developed to bring modern fully internal cable routing to the custom handmade bike market. Designed to fit inside a conventional 1 1/8″ upper headset cup, the Columbus Trittico features a unique Trefoil fork steerer tube that outperforms many other shaped steerers. Plus, a creative stem solution delivers unmatched cockpit adjustability, without messing with your brake lines…
Columbus Trittico carbon cockpits integrate handmade bikes

The idea behind these new Columbus Components carbon Trittico parts was simple. Give handmade bikes the option to build fully internal cable routing with existing tubing – specifically headtube – sizing.

Columbus sells a lot of steel and (increasingly) titanium tubesets to custom frame builders. And even though most of those now use so-called ‘oversized’ tubing diameters relative to old school 1″ steel tubes. We’re still talking about a maximum 44mm headtube for tapered 1.5-1.125″ steerer tubes.
While oversized carbon bikes can often get away with going to a massive 1.5″ upper headset cup to fit shift & brake lines inside. Metal bikes start to look weird with bigger headtubes.
