|   Short vs. Long Cage Deraileur | JBurton
May 19, 2002 6:23 PM | | In which situations would a short cage deraileur be used? I currently have a long cage XT, but was planning on upgrading to XTR soon. I run an 11-32 cassette. Will the short cage offer any advantages in shifting? Obviously there is an advantage in the ground clearance, and I have banged my XT numerous times.
Thoughts? |

May 19, 2002 6:26 PM | | basically short cage= more clearance and more precise/snappy shifting, but it wont work with an 11-32 cassette

| Why then would Shimano even offer it? | JBurton
May 19, 2002 8:25 PM | | In the XTR group, the only cassette offered is a 12-34. In the XT group, there is a choice of 12-34 or 11-32. Why would they offer a deraileur that won't be compatible with its own cassettes? |

May 19, 2002 9:52 PM | | I'm using mine with an 11-34 cassette, shifts fine.
What you loose is the ability to go into some of the small-small combos, which you don't do anyway, so there's really no reason not to. If you should accidentally shift into small-small, worst that'll happen is you drop your chain.
Bennies snapier shifting, higher ground clearance and greater spoke clearance (should you bend it) cinch the deal for me.

The benefit is faster shifting and more clearance. |

May 19, 2002 10:17 PM | | when XTR was introduced, the ONLY derailleur option, the middle cage GS size
didn't have the total capacity needed to support EITHER one of the two
cassettes available with the group (the 12-32 8speed size or the 12-28 size)
with the crankset's 26-36-46 chainring spread (requires 40T and 36T respectively
but could only support 33T).
Shorter lengths weigh less is the principal reason as to why they're
used. Actually SS-cage models really only have the capacity needed
to support road bike gearing, but they've offered them for various
MTB groups over the years. Deore DX, XT and XTR have all had them at
various times. Hell, a decade ago shimano had a 13-34 cassette yet
they had NO derailleurs made that were rated to take 34T cogs. |

May 19, 2002 10:31 PM | | Shorter cage = less chain flop on rough downhills = fewer tossed chains on technical sections. Short cage deraileurs work best if you run your chain a few links short then completely avoid your big/big small/small gear combos. |

May 20, 2002 3:36 AM | | The short cage mech will work on Mega-9 cassettes, it will not work with a triple ring set up so if your like me and only run 1 or 2 rings you will be fine. If you use 3 rings go for the long cage. |
| Not so... | næstep
May 20, 2002 5:59 AM | | Makes no difference: 1, 2 or 3 chainrings, it'll work. I ran a GS for two years with a standard 3 ring drivetrain.

| It WILL work. Just no granny ring with smallest 1 or 2 cogs | DJS
May 20, 2002 6:34 AM | | big deal, who uses those gears together anyways? well - scratch that, I see lots of clueless riders on the paved bike path using that gear.
DO NOT shorten your chain less than 1 link+big ring+big cog.
If you end up in that gear by accident, bad stuff happens. Not worth it. Some goofball borrows your bike for a minute, goes big big, and you are one un-happy camper. |
