Mountain Biking - need advice from a bike shop owner that knows bikes well!

hey, i own a 2001 koan roast and is goign to upgrade it only the forks though. I have been told the junior T's work on the roast and have also been told the junior t's do nto work on the roast. I have alsop been told that single crown forks work better on hardtails and double crown doesn't. Which is true? And does junior t's work on a roast?

pics of my kona can be found at: http://www.freewebs.com/kona_roastbika/picturesofmybike.htm

Generally the Roast is more of a Dirtjump style bike,which would not fit in with a bike like an Evil Imperial or a 24 Letoy IV. Kona's Dirt Jumping bikes seem to do really well with a fork that has 5" of travel. They just feel right with that much travel. With your situation, a Z1 or Dirt Jumper 3 will do wonders.

thanks Danka for the advice u own a kona stuff right? if you do mine and ur bike is like similar so u know what a hardtail needs for suspension

thanks for the advice

Correct.

I've seen plenty of Kona Stuff's with DC forks on them. Kona claims they will support a DC fork but only up to 6" of travel (well, that's all their warranty will cover anyways). danka is right though, they aren't the best hardtail to put a DC fork on. If you're really set on a hardtail with a DC fork your best bet is something like a Norco Sasquatch or any North Shore Norco hardtail. If you want bombproof, something like a Banshee or .243 is also popular.

thanks again for advice! but i'd stick with my roast and get like dirt jumpers or some fox forks or a shiver sc :D

I agree as well DC forks on a hardtail are a bit much. The Marzocchi DJ forks are a good choice, as are the Fox.

thanks again for advice!!! i appreciate it!

I will just put in my 2 cents. I love the feel of a 6 inch jrT on my roast. Felt great for jumping. Kona also keeps the warranty live. As fo can it, should it, will it...it 'rides' best with a 5 inch for. If you want a dc try and find a jrT 2 OEM norco fork. It was a 5 in version of the jrT made in 2002.

There are quite a few forks out there that will take the punishment of a hard ridden Kona. My experience is very limited, due to budget, But I went for Marzochi Freeride dropoffs. Thanks to weight, had to change springs to the heaviest duty, but this medium priced fork has shocked me on what it has had to stand up to, and the lack of wear taken place in the 2 years I have had them.

Punishment it takes is on a tandem, ridden to the extreme off road, with 440lbs all up on it. Milage has been around 2,000, and as I say, the lack of wear, after its 2nd service is non existant. My only criticism is that it could still do with a stronger spring rate, as we do bottom out on the lumpy descents taken at full bore.
