Innovation takes place in and out of the classroom. Peter Wen, a mechanical engineering student at the University of Toronto and member of the schools Varsity Mountain Bike Team was tired of carrying a bulky allen key set. While fixing his bike on the trails he thought there had to be a better, lighter allen key set. There wasnt. So he blended what he learned in the classroom with his passion for cycling and designed the worlds first universal allen key. He calls it Telehex.
