Nothing beats the efficiency, simplicity, and straight-up fun of an X-Cal hardtail in 29er or 27.5". Great for XC racing, or simply shredding singletrack.

Old guy getting back into again (55). After looking at hybreds, fitness and mountain bikes this puppy fit the bill. Test rode many bikes, many brands and talked with the staff on how I ride the fit was great. At only 5'6" tall the seat post was a little high and could not be lowered because of the accessory attachment bolts took an inch off and now the seat and fit is much improved. The X Caliber 9s'components are great improve over the 8 and well worth the extra $. 100 miles into ownership and I am loving it.
