Hey guys!! nobody want to help me or what?
 
Cykario,

I've just joined too. I dont know where this site is based ( Europe?). I'm in UK and its 2.30am, I should be in bed.

Any how, re: your chain set question. Without being nasty, I wouldn't bother upgrading from your current one to the one you suggest, as there wont be that much difference to notice.

If you can afford it go for a shimano deore or lx chainset.

You'll notice the diference. Also, upgrading your shifters will make a massive difference to your shifting. I had deore and went to xt, and couldn't believe the improvement.

Similarly, if you upgraded , again, to deore or lx shifters you'll notice a massive difference for not much cash.

I hope this helps

cykario,
Give responses some time man just be patient. Anyway what style of riding are you doing? If you are looking to start a overall upgrade campaign that begins with the cranks, you might want to start looking at new bikes. From what I gather you spent about $250 on this bike. For starts a new crank is going to run you, $32+ shipping. probably $40. So lets say you switch to alivio shifters, that is another $32 probably $40. Then you decide to upgrade brakes......
 
Sorry guys =P, so...........your suggestions are.....1) look for a new bike 2) Dont upgrade your current crankset 3)Get a new chainset (Deore or better) right?

I usually ride 2 o 3 times in a week. (Not downhill)
 
You can put anything you want in there, but chances are you will also need a new bottom bracket.
 
Whether you upgrade components or replace the bike outright depends upon how many miles you are doing and how hard those miles are on your bike.

Typically, if you need to replace one part of a particular component group (e.g. Tourney) due to its lack of durability or performance for the type of riding you are doing with a higher-end part (e.g. Deore LX), then you will probably be replacing other parts on the bike pretty soon as well.

If you are wearing out or breaking parts on a somewhat regular basis, then you may want to take a look at what bikes others are riding who ride in the same places you ride. Then head to your local bike shop for some test rides (and your bank for some budget calculations).

You have to be careful upgrading parts on a sub ~US$350 bike (typically a hi-tensil steel or 3-tube Cro-moly frame and comfort suspension fork) since you can easily spend enough (or close to it) to buy a brand new bike outright with the same components AND a much nicer frame and fork (e.g. full cro-moly frame and entry level performance suspension fork).

Typically components in the Deore or Deore LX groups provide a very good price to performance ratio for most mountain biking in a variety of conditions.

Just try to keep in mind when making upgrade versus buy decisions that how the bike performs depends on how the frame, fork and components work together as a whole. So just be conscious of significant mismatches between frame, fork and component performance and durability.

Also note that the frame, fork and components that make up a bike are much less expensive when purchased together (i.e. as a bike in a bike shop) than trying to purchase each bit individually.

Good luck!
