Have been seeing more and more bikes that look different to the norm lately, what do you guys think of the new 2007 GT DHi?

Well that bike did get run straight into an immovable object at high speed. What else would you expect to happen?Eggzoi said:Looks fine to me, I'm all about performance.
This however concerns me. Kink could be a weak point.
No idea what they were getting at with so cal speed???, but I will ad the ping pong decals were about the lamest thing ever.vitox said:stikman is that "so cal speed" sticker on top of the seatstay the 21st century version of the table tennis logo?
That would be great if it was. You could raise and lower the BB and shorten or lengthen the chain stay.peachy said:is that an adjustable BB? depending on the "bone" u use?
If you take a careful look, you'll see the BB is attached to the swingarm and front triangle, and it's position is governed by where the swingarm is in it's travel.bballe336 said:That would be great if it was. You could raise and lower the BB and shorten or lengthen the chain stay.
Just like the i-drives of old...I have an '03 (or '04...can't remember) i-Drive XC frame hangin' in my garage...(went through 3 of those frames...warranties of course...now I think I'll build it for a buddy of mine who's starting out...) this design looks the same (dogbone) they just got rid of the BB eccentric design that was prone to issues from being one of the most stressed pieces (The BB eccentric was the failure point of 2 of the 3 busted one's for me....just cracked in half!!!) The old i-drive pedaled amazingly, was prone to brake jack (locked out the suspension...not squatted...), and did a decent job for me as an XC training ride....I'd like to get some time on one of these new DHi's though....just to make the comparison to my new Rotec....(and to see how much better my bike is!!! I keeed, I keeed!)Superdeft said:So the BB moves with the swingarm, interesting.
Look closer. The BB is attached to the swingarm so it doesn't bob while pedalling. But it remains in the same position throughout the travel. It is riding on some type of bearings and that link piece would prevent it from moving with the swingarm. It is attached but independent at the same time if that makes sense.Superdeft said:If you take a careful look, you'll see the BB is attached to the swingarm and front triangle, and it's position is governed by where the swingarm is in it's travel.
I think we agree here, do you think the bb stays in place with respect to the front triangle or the swingarm? The latter would mean no chain growth, but I'm unsure as to what that might also do to pedaling.bballe336 said:Look closer. The BB is attached to the swingarm so it doesn't bob while pedalling.

The botom bracket stays in place with respect to the front triangle. The position it is in in the pictures is where it would stay regardless of swingarm position.Superdeft said:I think we agree here, do you think the bb stays in place with respect to the front triangle or the swingarm?
