Bike Rumor caught up with a Swiss rider to check out their custom 44Bikes Kid Dangerous single speed 29er. The bike has some pretty short chainstays utilizing flattened tubing for better lateral stiffness. The bike also includes internal routing and some other nice touches. Check out the rest of the article for more info.
“He found that the bike was really stiff and the tire tended to bounce around a bit, which is what led to the flattened stays…they’re there to add lateral stiffness, not really for vertical compliance.” – Bike Rumor
