From listening here, and talking with others, I take it the 'obvious' is that short cage can't
handle as wide a gear range.

The advantage is, AFAIK, that with a shorter cage, bushing slop and other play in the system has a
reduced effect on the crispness of gear changing, because it is acting through less leverage. This
means for people running gears within the narrower range the short cage can handle, it is a better
option - crisp, sharp gear changes, and slower effective wearing.

Disclaimer: This is purely hearsay and conjecture, but it's probably all true anyhow.

It has to do with the 'chain wrap capacity'. You take the difference between the largest and
smallest cog in the rear and the same in the front and add the two numbers together. This is the
'chain capacity'. You match this number with the rear derailleur capacity number on the spec sheet
(and max cog number you want to use). Since us downhillers only use one cog up front the capacity
number is small so we should use a short or mid cage rear derailleur. I use mid cage (GS) XTR
rapidrise on my DH bikes. I've seen road derailleurs used as well. It's when those XC weenies shift
into the small/small combo the chain has to have somewhere to go.

HTH

Mike -BTW the mid cage is shorter than the long one....duh!

And I thought it was longer than the short one - Thanks for clearing that up for me.

Ahh.....great explanation ( way better than that Rimmer dewd ;^ o ) Wasn't sure which to get for
the DH sled.

Now, which one was longer???

Thanks (both of you)!

The more lengthy one.

Shocker? Oh yeah? Well, google it MoFo - when I can help, and I get there first, I always

Nothing yet, but I'm learning a valuable lesson. It's not good enough to have the cash ready, you
must also have good timing.

Was going to buy another pair of Stiffies and I find out RRR is shut-down and being sold ;~( So I
decide to go for a pair of Purples, but I'm having a difficult time finding anyone with a full set.

Now my truck needs new rotors/front brakes and shocks all around.....sheesh, always something.
That's ok, it aint stopping me from my plan......bwahahaha!!!

Sure look pretty. Will it fit on a SS?

The mind serves properly as a window glass rather than as a reflector, that is, the mind should give
an immediate view instead of an interpretation of the world.
