South African company cSixx provided the last-minute solution for many a World Cup racer's 1x10 drivetrain needs, as seen here on Jean-Christophe Peraud's Lapierre. The team apparently couldn’t' get a hold of the correct size on such short notice, though, so a chunk of rubber serves as an emergency shim. (Image credit: Jonny Irick)
Kona privateer Spencer Paxson's setup is impressively versatile. Here, he's using Easton's tougher Haven Carbon bars instead of lighter-weight, less durable, or narrower options. (Image credit: Jonny Irick)
