9:ZERO:7 Aluminum 170mm Centered Frame 1-1/8' Head-Tube

Named after the area code of Alaska, the 9:ZERO:7 170mm 1-1/8" head-tube frame is crafted out of 7005 aluminum and offers a host of features to optimize your fat tire experience. Starting with an elongated head-tube and longer chain-stays, the 9:ZERO:7 features six rack mounts, three water bottle mounts, fender mounts, and full cable housing.

A non-offset, 170mm centered frame features more tire clearance than the 9:ZERO:7 135mm offset frame. The symmetrical rear wheel design also stronger than an offset rear. The 170 makes building up a pair of summer wheels super easy.

While featuring all of the benefits of the original 9:ZERO:7 aluminum frame, the 2012 frame utilizes a hydroformed top tube. This dramatically improves standover height without adding excess weight, making it easier to get on and off the bike in soft snow conditions. A hydroformed down tube is used to enhance fork crown clearance and allows the use of many different kinds of forks.

The chain and seat stays have been redesigned to accomodate even fatter rim and tire combinations. With the increase in clearance, the new 9:ZERO:7 easily accomodates 100mm rims. The 170mm frame is also ideal for those seeking to run Big Fat Larry tires.
