bored at work, thinking up questions.
« on: November 28, 2008, 05:25:02 PM »
ok so I keep looking at sites for parts and wondering whats what and why that? so here are some questions that baffle me.

-cassettes, most of what I see are 9-speeds, I have an 8-speed now why would I go to 9 if I bearly use anything above 5th speed, also wouldn't that put more strain on the chain?

-derailers, sram x.5, x.7, x.9, shimano's whats the deal, and what does someone like me really need (not racing, just looking for good reliable, crisp shifts), I mostly ride for fun and exercise and mostly at loyce harpe.

-shifters, the ones that came on my bike are shimano 1 peice lever/shifters (shifter and brake in one unit) and seem to work fine, but my LBS keeps tellin me to look at upgrading. whats the advantage and what do I get?

-bottom bracket, is this the bearing pack in between the crank arms? how do you know which one to choose? I think mine is made out of plastic or something(stock sr suntour crank) so I should probably take car of that before something happens.

-cranks, do I really need to upgrade this? whats the advantage? weight? what about the gears? and why do they have 3 gears? really why not just have 1 or 2, I pretty much always use the middle gear.

well thats all I can think of for right now, enjoy.

The more you ride the more you will shift and invaritably the more you will find yourself in that Bad place between :o gears either spinning too fast or hammering to hard :P that extra cog makes that transition a little smaller ;)don't look now but rumor is a 10 speed is just around the corner.
Shimano or Sram is personal preference when refering to derailers and shifters, I have both and like different characteristics of each but both work equally well. For off road riding, if you are upgrading I would go Shimano XT or Sram X9 the price difference between that and a LX or X7 setup is not that much.
With this upgrade you will get more reliable shifting and a stronger spring on the jockey wheel cage which keeps that DANG chain from beating your beautiful chainstays to death :'(
BB's are the bearings between the crankarms, there are a few styles. I am guessing you probably have a ISIS set up where the bearings are internally in the bike. Most upgrades go with a external bearing cup that threads on to the bike leaving the bearing cups exposed with the advantage of being stiffer by way of a larger bearing and crank shaft.
Check out the Park tools site for a lot of detailed maintanance reference :)

depends alot on your personal needs.

You can get any kind of cassette you want.  Just go to the Local Bike shop and they will get it for you.

In my experience, most of the time, the more you pay, the better performance when it comes to shifting you get.

I have Sram X0 complete drive train on my bike.  Built it all up for around 250 dollars by shopping on the web.

Its a crisp shift and the lightest system out which, in the grand scheme of things, weight to power ratio does make a determination on your overall speed.

I use twist shifters which is an entirely different debate.  Mainly I use them, cause 1. I dont shift often, 2. its the lightest set up. 3. Hard to crash into a tree and break a grip shift, but I have seen many triggers break in the backwoods.

The biggest high dollar difference I see, is shifting under pressure.
The scenario: You come around a corner and you got nothing but a ridiculous sharp uphill that goes for a small distance.  under pressure XT, X0, XTR will deliver, LX and others may just lock up on you forcing a dismount.

If you dont care about dismounting in that scenario, and can anticipate your shifts use whatever you want as LONG as its a brand name.  Always use SRAM chains, Drive train just match the brand.
Deore is the lowest
XTR is the highest.
in SRam x 7 is lowest, or just sram is lowest and x0 is the highest. 

Hope that helps,

Shred!

For the most part I agree with Nk and Anthem.

Just a point about shifters. The higher end shifters will definitely make a difference.

If you have an X9 or a Xt derailluer, and you are using a X5 or a Deore (not the lowest Shimano), you will degrade the performance of the derailluer.

Like Naked said you can make these upgrades fairly modestly either at your local bike shop or online.

You can.

The people who know how to haul ass, use all three.

BUT

there are people that can Haul ass on one gear.

but there are no ten speed cassettes for mountain bikes.

either Shimano xt or higher, or Sram X7 or higher.

Ride what you got till you either KILL it or the performance is no longer acceptable to you :)

For the record Gregg, I have seen a ten speed MTB.  And it is Ted's. Or was Ted's.

And Anthem gave you the best advice of all.

Bring some cash, Im sure you can upgrade on the spot tomorrow for cheap at Boyette round 9am.

Well let's segway convo's then.

Is 10 speed necessary?

I always thought the fastest bike I ever had was a 6 speed.

It was not by choice, just poor performance, but those 6 gears were fast!

due to my current finances I will be taking the advise of riding it till I break it, unfortunately I think that will be very soon for my fork :-[
