dual suspension selection

Hey guys! I am looking for a new dual suspension bike and i had a few questions...

1. I currently have a trek mamba 29er and i was wondering if i bought a trek dual suspension frame then i could put it on the wheels and handle bars on the dual suspension frame. Would i have to buy the same size frame or have to buy a frame that had 29 inch tires on it to fit my tires?

2. Does anybody have a remedy 8 29er, top fuel 8, or a fuel EX 8 29er? i was wondering how they liked it?

3. Is there a bike with a pair of dual suspension shocks that i should not get that anybody could recomend? Such as a bike that looks great but turns out for the shocks to bend or not be able to hold the amount of pressure and break?

Thanks!!

Also is there such a thing as a dual suspension kit that can turn your bike into a dual suspension? I've looked online and cant find anything but i was wondering if any one else had heard of this?

No such thing as a dual-suspension kit, but Cane Creek (I think it was them) used to sell a pretty darn nice suspension seatpost.

On the frame swap thing, I did several of those during a period of stability in standards as my son was growing up. These days you really need to have a specific target bike, and then go through part-by-part to see what's possible to move across. If wanting to move your 29er wheels and tires, then you'll need a 29er frame and fork with the same dropout configuration as on your current bike.

I have been reading about these seat posts and i am very interested because i don't exactly have all the money for a full suspension bike. what does it mean for a seat post to be 27.2x450mm. or 30.9x400mm or 31.6x350mm. these l switch around in different ways such as 27.2x350mm but anyway, i wasn't sure what those sizes were actually referring to on the seat post and do i have to match those specifications to my current seat post? thanks!!!

The numbers 27.2, 30.9, and 31.6 refer to the diameter of the seatpost itself. Whatever diameter seatpost you currently have on your bike, that's what you need. If you pull your post, the diameter is sometimes stamped on it at the very bottom.

The larger number -- 450mm, 400mm, 350mm -- refers to the length of the post. This has to do with how much of the post ends up insider your bicycle's seat tube. Some riders prefer shorter posts to save the weight. Some bicycle frames have welds or other barriers in the seat tube to prevent a post from going past a certain point. Other frames can take any length seatpost. Best is to measure your current post length. Match it if possible, or stay close to it. If you buy a new post that is longer, look insider your seat tube to see whether there are any obstructions.

Edit: Those Cane Creek Thudbuster posts look like they can simply be cut like any other post to whatever length you need. Note that such is not typically the case with suspension posts, but the Thudbuster design means that the post part is just a post.

They are heavy and the weight is way up high on the bike, Very Bad..

They are great for mellow trail riding but are Un-damped so the 2 to 3 Inch travel Is like a fat bike tire In that aspect Except,,,,,,,

The fat bike tire is controlled by the rider bending his legs, making His/her body the damped shock absorber..

The seat will only compress and rebound Instantly at the worst time and the worst time Is anytime your rear end Is in the saddle....
On real trail riding we need to be OFF the saddle and ON our feet to help the bike absorb things..

You try and make the Thud buster a substitute for controlled rear swing arm suspension with managed rebound and compression on any real single track you will know pain,,, Intimately !

That thing is great for fire roads and nasty pavement cracks but does not belong on a Trail bike...

Good entry level dual suspension,,,,,
So many.

Giant Stance with the lower spec.. $2200 ish
Trek Fuel, again at the lowest spec level,, $2000 ish

If you can stand heavy,, I cannot,, then Bikes direct has some options maybe in the $1500 range,,maybe.
But these Internet bikes are nothing I would want. I would rather buy a used quality made bike...

My Scott Spark Is the Lowest spec'd of the Spark line,,I love it,,$1900 new,, I got a year end closeout for $1500 before my trade in..$1280 after tax.
A year on it and Its still great. but Its a light duty trail bike not a Black Diamond trail eater...

IF I had $2800 burning a hole In my pocket I'd move to the Trek Fuel EX 8 In a heart beat, rip the tubes out of it and strip It to a 1 X 10 before the first ride...

But I don't

No, that is not a good idea. That is a bad idea.

If you're planning on buying a frame and want to use 29" wheels from your Mamba, you have to buy a 29er frame. The size of the frame should be the same size as your Mamba provided you've determined the Mamba is the correct size for you. A word of caution. Buying a frame and building it up is not the cheap way out. First, you have to be a bike mechanic, with a number of uncommon tools, in order to build the bike up. Second, parts are not always transferrable from one frame to another, and cables, cable housing and incidentals will eat up some of that "savings". If you're just an average rider, who can change a flat or maybe a chain, but after that you rely on a bike shop, IMHO, you'll be better off buying a complete bike.
