One of the questions I get a lot is, 'What are some of the differences between SRAM and Shimano?' For the answer, I did some digging on the SRAM website and came up with the following:
Well, SRAM's ESP design uses a 1:1 ratio. This means that for each millimeter of cable moved in the shifter, an equal millimeter will be moved in the derailleur. This allows a greater acceptance of off-road conditions (dirt, water, sand, etc.) and also gives SRAM a unique shifting technology. Conversely, Shimano uses a 1:2 ratio for its shifting systems. This means that for every one millimeter of movement in the cable there will be two millimeters of corresponding movement in the rear derailleur. The ratios are not the same; therefore, you cannot use an ESP shifter and a Shimano derailleur, or vice versa.
What does this explanation mean in real life applications? In short, it means that Shimano derailleurs shift as well as SRAM derailleurs UNTIL something interferes with the shifting process (sand, mud, dirt, water, crashes). Once that occurs Shimano derailleurs, because they move two millimeters for every millimeter of cable pulled, become 'out-of-tune' more quickly than the 1:1 based derailleurs offered by SRAM.

seems like the explanation is biased in favor of SRAM

I agree.. remember shimano are the only Company doesn't have compatibility... Since they hold the big piece of the pie.. they say "you follow or you go down"

SRAM cant deny the fact the a large pie of the market is still in Shimano's hands, so that's why they're still the best on grip shifters. I like the new dual control of Shimano, but I find SRAMs system better.

But here's the interesting part. SRAM will offer two new mountain bike cassettes in 2006 to compliment its X.0 rear derailleur and trigger shifters. - PG-980 and PG-990 both utilize aluminum "spiders" to carry their cogs.
- The high-end PG 990 uses a full anodized red spider
- The more-affordable PG 980 uses a mix of a full and mini spiders to carry its cogs.
- Both were designed to carry SRAM's improved PC-950, PC-970 and PC-990 chains more efficiently
- Both cassettes will be available in 11-32 or 11-34 tooth options (where the 11-34 will now feature a more mild 30 to 34 tooth jump instead of the previous more aggressive 28-34 tooth jump)

warlock are you using the sram cogs?
i got the xt cassette for my x9s 'cause they are still lighter by a few grams.
i've read that the initial price of the x0 triggers is to the tune of $240. phew! that's already an 04 xt integrated shifter, fd, rd & cassette!

Honestly I'm not that smooth when it comes to shifting and considering that huge jump (SRAM), chances I might destroy the cogset. yeah... velonews claims it'll cost about $225 link, I'm not really sure which is correct but with that price, guess my X.9 triggers will last me forever ;D

Sometimes its a kinda a personal preference also it people start talking about intuitiveness, shifting and other stuffs relating to drivetrains. Cons...SRAM X.0 is very expensive, now they have this carbon model, at $225 man! compared to the original model @ $120...crazy

i find that SRAM's not that durable. my first experience w/ SRAM and i broke my new Rocket shifter in less than 2 months. i have my Shimano Deore for 3 years and it's all bang up but still working. Lucky hit on the SRAM? myb.
I like the SRAM triggers.
SRAM's rear D do shift really nice too - crisp!

tried both systems and found its really a matter of preference, f u need a lightning quick shift from a low gear to high gear or vice versa , sram can't be beat. i find it easier to tune the srams ( but hey i'm no expert mechanic). shimanos are here to stay and will be the most available shifters in the market. personally after using both systems its the srams for me.
