I am about to buy a 2003 Giant Warp DS1 (japanese model), Yes i was asking about it ages ago, but i got the price down some more now!! ;)

But it has a TRUVATIV FIVE-D 42T 170mm only on the front, and I was thinking i'd like to get a smaller ring for the front if a 42 teeth ring is a bit big (i'd like to be able to ride up and down a bit) I was also thinking about getting a bash guard too. It's got 4 bolts to attach the ring, so i guess its a 104BCD.

But is it easy to change, and do I have to worry about what brand to buy?? It'd be nice to swap depending on what i'm going to be riding, or to just find a size thats good for all.

What size would you suggest???

In the future I guess eventually i will get a triple ringset on the front and a derailer. Is this also gonna be a case of just bolting on a few bits, or would I have to change the BB and cranks????

thx for the help!!!

You should just go to a 2 ring setup with bash guard, add a spacer to BB, XT front derailleur & triger shifter, adjust chain length.
The crank arm doesnt care about brand loyalty as long as the bolt pattern is the same, run any sprocket & bash you want.

Thx man, so I'm pretty much free to add what i want to it all.

What sizes are good for a twin ring setup, I'm thinking 32t and 42t (so i can use keep my current ring). I thought that some rings were meant specifically for multiring setups, and single ring setups. If this is true, then the ring that is on there now won't have the little step tooth (sorry, i don't know the name of it) to help changing gears and so I can't use it as the big ring in a dual ring setup.

Does this make sense or have I lost it. If that is right then does it go both ways?? ;) in that a ring meant for multi ring setups will have the step up tooth and not be ideal in a single ring setup??? oh man I gotta stop thinking about this!!!!

Ok so i didnt mention that yes it does need the ramp pins to go to the larger sprocket.
For a 2 ring set up you should run a 32 or 36T & 22T, most common is 32T & 22T. I run the 32x22T setup & almost never need a bigger sprocket. Go ride & see what you need. Also if you need to run a tensioner because the trails are so rough the chain comes off there are more chain tensioner options for 2 sprockets than 3. Going up hill you want the 22T all the rest you will be in the 32T sprocket.
Another brain fart, some DH cranks dont have the holes for the 22T sprocket, they are lower. If that is the case you will need new crank arm.

Thx again for the info, this is kinda what I expected, but as they say, "Assumption is the Mother of all ****ups!"

I think for now I will get a something like a 32 or a 34 tooth ring and see how that goes. For now I will be riding the streets of Tokyo, but there are mountains around so I hope that I can it get out there, just the issue of taking the bike on the subway to get there!! :(
