Sram X.9 or Shimano XT rear derailleur?
I am looking to buy a new derailleur. Could anyone recommended which
on of these would be a better choice, a Sram X.9 or a Shimano XT. I ride a lot of aggressive cross country with some downhill mixed in. The most important thing is that it's durable and it needs a strong cage. Weight is no issue. Thanks for the help, John. |

I ride a lot of aggressive cross country with some downhill mixed in. The most important thing is that it's durable and it needs a strong cage. Weight is no issue. Thanks for the help, John. First off: what are your shifters? SRAM derailleurs must be matched with SRAM shifters. The mechanical advantage of Shimano and SRAM derailleurs is completely different, and so they are completely incompatible. Second, as far as weight, here is what my favorite bike shop advises. The owners/operators in this shop largely service the downhill crowd. In their store I will see one customer every 15 minutes pushing a $6,000 45-pound full-suspension downhill rig that has some kind of hideous problem. Busted frames, broken fork stantions, sheared-off stems and bars, derailleur hangers torn clean off, seatposts sheared off at the frame, etc. The derailleur they spec: Deore. XT and XTR have alu cages, so they are actually more fragile than the cheaper versions. Deore has steel cages. The expensive derailleurs are made to be light. They are also made to withstand pivot wear due to their sealed brass bushing pivots and forged cage plates. Out of the box, a Deore unit will shift as well as XTR. But barring accidents, after 5 years, the XTR will still shift great, and the Deore will be sloppy. This is all good in theory, but some of this shops regular clients destroy on average a derailleur per month. If you are doing any kind of real mountain biking, you'll never wear out a derailleur; you'll break 'em. |

The problem is I keep breaking the cages or on my current one the cage is badly bent. Maybe my hanger isn't working right. Either way I would not have a problem getting sram shifters if there were a derailleur that would be more durable. Or should I just deal with having the replace them more often then I would like. Do you think I should get a new Deore or is there something better? |

The reason you break derailleurs is your riding - you are running into things. So you should make the reasonable assumption you will continue to break derailleurs. The reason everyone here is recommending that you buy cheap Shimano derailleurs is because they work well and are cheap. More expensive derailleurs are easier to break, because they are made with more alloy parts and less steel. SRAM derailleurs are no more durable than the cheap Shimano ones. Based on your question, I assume a bike shop is trying to sell you something expensive... Ignore them. Your 'hanger' has nothing to do with you breaking derailleurs. If it is not straight, then get a shop to align it. If it is not straight, then your shifting will be crap no matter what derailleur you use. |
