well I was riding today and my der. exploded. Or atleast it seemed like it.

I guess I got it caught up in a branch and it ripped right off. I really want to ride on thurs. so I was wondering what my choices where just in case my LBS only has a limited amount of der. in stock?

Here is my setup: 9.0 gripshift shifters with 32 tooth cassette, can I throw any der. I want on there?

what is the difference between a 9.0 and a 9.0 SL <-(what I had)

I am thinking I will go with a 7.0 because this will happen again with the type of riding where I am.....

If I am in a bind, can I throw a shimano back there?

What is the difference between sg and sgs?

When do I need a long or short cage?

I know I have a lot of questions, thanks for the help....

9.0 SL requires a SRAM rear der.
sg is mid cage,sgs is long cage.
The 7.0 der would be fine.
You will be very frustrated with a Shimano der, you can't quite get it to shift right with SL.
Cage length has to do with the tooth difference front to rear. The exact spec is in the lit. in the der. box, I can't remember offhand.

In essence, short cages are for single and some dual ring front setups. Long cage is needed for a triple-ring front, or a dual-ring front with a cassette over 28t in the rear.

That's oversimplified; however, it's a reasonable general guide.

You can't run a shimano der., like the good reverend said. SRAM makes shimano-compatible shifters, but they're not the numbered series; they have names like Attack and Rocket.

At the moment, SRAM only makes one cage length (long) to my knowledge, but a mid-cage version is coming out soon with the X.7 and X.9 series of parts due in summer.

nope wrong, w/ the lengths. you can get a mid and short now. b/c i have both in my hands as we speak

What series is the short cage? SRAM guy told me it was mid/long only for x-7/x-9, and due out in June..?? Hmmm? No holding back now...what's the dillio??

the 9.0 and 9.0 sl have been in short and mid(long) for a few years now

 

[MikeD]

Huh...I had no idea. I'm waiting for the X-series to come out before going back to ESP shifting...very excited. Just can't decide on trigger or twist. Long live 8sp!!

I think this might really hurt Shimano's Saint system, btw. A viable trigger and nice derailleur...wow!

well i always knew they'd make a move into the trigger shifter market. they've been tryin to get it right over the last few years and have tried a bunch of stuff that not many ppl know about. i think things are gonna be big for sram in the next few years on many standpoints. i've always liked the twist shifters, just something i haven't been able to use efficently is the trigger....

These guys got it good on the cages to choose, but I thought I'd point out one quibble: you can use a short cage with a triple. My little brother rides in Massachusetts and is strong, so he runs a 12-28 cogset (24/34/46 rings) and a short cage XT on a bike I built so long ago we won't talk about that. Works great in the Lynn Woods, I hear.

 

[MikeD]

Yes, you're right. I thought I was pretty clear...

the short cage w/ the 12-27 is killer trust me that's what i used for a long time.

I did too, but that it was "clearly wrong" and I tried to soft pedal it. Short cages are used on roadies and cross bikes with triples all the time. Just to be clear.

Hakuna Matata brother man!

Short cage /long cage only becomes an issue when crosschaining. The longer der. can handle more tooth differential. If you run a lot of chain you can get away with a big-big misshift on a short der., but if you shift to the small ring and any but the biggest cogs the short der won't have enough length to keep tension on the chain. This won't really hurt anything, except maybe wearing notches in the keepers on the der. cage, but people will deride you and your saggy chain. That, and the fact that you need to use the small ring in the first place.
Me, I run a 30t/12-26 with a Dura/Ace der. and 32t/11-28 with an XT der.

Or when you're about to smack your derailleur on a rock...I've had far fewer impact-related problems with the shorter cages...and I appreciate the stronger springs on the roadie mechs.

i use to run grip shifts with an xt der, it worked fine although i had some sketchy routing it never messed up until the stupid bike shop ppl tried to adjust it when all i wanted them to do was fix the front der:angry:

The 9.0 SL has been discontinued in lieu of the X.O. For 2003 the 9.0 gets aluminum knuckles where the 02 plastic ones broke. Go with a 9.0 if weight is an issue, if price is an issue get the 7.0.

A Shimano mech will not be compatible with the cable pull of your particular SRAM shifters.
