Way back in 2006 Gary Fisher introduced the HiFi and with it Genesis 2.0 Geometry. G2 was a radical project to improve the slow speed handling of the original Genesis Geometry without affecting the dialed high speed stability and climbing characteristics. Fork offsets were adjusted, trail figures were modified, and the HiFi fast became one of the most popular 5" travel trail bikes ever.
But Gary can't leave well enough alone. Sometimes, you don't need 5" of suspension. Sometimes you will gladly trade inches of travel for a lighter bike. Sometimes you want the ultimate cross-country machine because that's what the trail dictates or that's simply who you are.
