Huh? Uh, while a DHR is sort of remotely similar to an F4 (but really not all that similar), the GT is completely and entirely different. Totally different. The only similarity is that it has lots of travel and is made to go downhill, off-road.
Sorry, but it does require a special guide due to the fact that the BB rotates independent of the swingarm and main frame. The guide shown in the photo would not work if setup that way - that was just an off-the-shelf guide we sent them for some test fit-ups.
We've been cooking up something special, so keep your eyes peeled when looking at Interbike photos.
I give big props to these guys...small cali' office of people keeping GT alive, they have to battle against the bottom line of Pacific who runs a tight business model-but it works. For them to come out with all the new protos is really cool. I think the bike would be really nice given a better graphics kit...props to the GTers.
I really like the looks of that bike. If it ends up being like the old DH-i I am sure it will be awesome. I have the same i-drive design on my XC bike and it works the same as the old design that i have on my dh-i, but it is lighter and much easier to service. GT has always taken their DH race bikes seriously and i am sure this one will not disapoint.
