A natural evolution of our legendary Asura Frame, the ICARUS is our fully heat-treated Chromoly 26″ frame made for dirt, skatepark and street riding. Designed & developed over 3 years with MTB street pioneer Niklas Tilk, the ICARUS utilizes a brand new tubing construction as well as handy features such as a Mid Sized BB style bottom bracket, rotor tabs, beefier dropouts with chain tensioners, greater compatibility for suspension forks, and oval/tapered stays for maximum tire/sprocket clearance.
The short/snappy geometry and reinforced tubing constriction make the ICARUS the ultimate do-it-all 26″ machine. If you need any proof of what the ICARUS is capable of just take a look at Niklas Tilk’s Radio vdieo projects. Say no more.
