Simply stated, the 1991 Alpinestars Ti-Mega is the most technologically advanced mountain bike in the world period. At the heart of this technological breakthrough is the EOS frame system. We developed a revolutionary design consisting of radically short 15.9” chain stays and curved seat tube for the ultimate combination of power climbing, traction and tire clearance. Combine these features with a titanium frame, fork, handlebar, stem, and seatpost made of oversize titanium tubing (renowned for its tremendous strength and light weight), and you have every racer’s dream machine. Well, dream no more – the Ti-Mega EOS is your competitions worst nightmare.
