    Date Reviewed: February 11, 2008
    Favorite Trail:Shermans Branch
    Duration Product Used:More than 3 years
    Price Paid: $40.00
    Strengths:Easy to set up. Seems like it will last forever.
    Weaknesses:Can be pricey.
    Similar Products Used:LX,XT and other lower grade Shimano
    Bike Setup:2004 Superlight,Marzocchi MX Comp fork, mechanical Avid disc,various wheel and tire combinations
    Bottom Line:I bought this XTR rapid rise used for about $40. I coupled it with some old Scram grip shifters. It stays in adjustment and has never ghost shifted on me. I do my own work.With it I'm confident to stand on the pedals and down shift as needed. As with any nine speed the adjustments to keep it in tune are small. You have to be adaptable to shifting backward.I think XTR is overrated and too expensive. When I replace this unit it will be XT or another used XTR.

    Strengths:Rapid rise, solid, smooth
    Weaknesses:None after the first 2 rides. Once you've got used to rapid rise, you're hooked
    Similar Products Used:Other Shimano
    Bike Setup:Scale, XTR
    Bottom Line:Rapid rise is the way forward if you _ever_ hit an unexpected uphill. That must be anyone who's not doing 100% DH. Try it and you'll be converted. (I've given it 4 Chilis for value because now you can get rapid rise in XT). Apart from that, it's as precise and smooth as you'd expect from XTR.

    Bottom Line:this review is for the 2007 model. It's so beautiful and it shifts like nothing I've tried before. It shifts perfectly even when running 20mph over rock garden. The SGS (rapid rise feature) is very usefull if you are serious about climbing. Much better then the SRAMs, possibilly because of the rapid rise. I've tried X0 and, even if it's a gorgeous derailleur, I prefer the XTR, it seems smoother.
    I use the XTR with SRAM Attack triggers (best ever shifter system).

    Bottom Line:Looking for some help / advice.
    I have a brand new B1 Team XC Pro fitted with XTR rear mech, Dura Ace ( 9spd. )chain, SRAM 9 speed ( 11-34t ) cassette. This works perfectly on the bike stand - shifts like a dream.
    Out on the trail it will not go uphill at all - any slight load on the pedals causes the chain to jump the cassette sprockets as though it is a brand new chain on an old cassette. This has been set up by a bike mechanic and I have also spent more than 12 hours trying to sort this thing. Please help.

    Strengths:Light. Great shifting. Easy to adjust. Rapid rise is the only way to shift! Quick shifts. Always shift in bad condition and during excessive bumping and chattering on descents. Shifts on the climbs even when cranking on the pedals.
    Weaknesses:Finish scratches easliy. Not sure if it could take a huge direct hit because of "lightweight construction", although I'm not sure of what would. A little expensive.

Mine has worked fine for over 2 years, and I downhill, dirt jump, freeride, and trailride with it! This derailleur will always put you in thr right gear no matter what the conditions are.

    Strengths:Shifts well when properly setup
    Weaknesses:Very sensitive to cable friction when shifting to high gears.
    Similar Products Used:Various
    Bike Setup:2003 Fuji Adventure SL
    Bottom Line:Had problems with cable friction. Would not shift into higher gears but would always shift to lower gears no problem. Turned out the problem was too much cable friction. I put on a rollamajig and that fixed it. It still is a little slow to shift to higher gears but at least it shifts. I think it needs a stronger return spring to pull all the slack out of the cable. There is not much room for error with a 9 speed system so cable friction has to be small for it to work.

    Favorite Trail:Fullerton Loop
    Duration Product Used:3 months
    Price Paid: $120.00
    Purchased At:local bike shop
    Weaknesses:Two significant weaknesses... the product itself and Customer Service at Shimano. After running this product for less than three months I bunny hopped a curb on the Fullerton Loop at the first Euclid Crossing. No big deal... no hitting the derailer on anything...nevertheless, upon landing the bunnyhop, my derailer sucks into my spokes and nearly jacks me off the bike. There were two witnesses who observed what happened, and If I thought Shimano was going to play the “rider error” card, I would have got their names. Anyway, I take the product back to the local bike shop and the Shimano representative doesn't even request the product for review, and plays the rider error card.

    My personal opinion, if I am going to pay over 100.00 on a product, I expect it to last longer than three months. And if you going to call bunny hopping a curb, rider error... you should at least look at the product to evidence if this is indeed the case.
    Similar Products Used:SRAM XO
    Bike Setup:Cannondale Jekyl with XT XTR drive train components.
    Bottom Line:DO NOT BUY THIS PRODUCT! This is my first attempt, and likely only, attempt to contact Shimano concerning their products. In my opinion, this is a poor product. Beyond this, this service policy is even worse! If this is how Shimano does customer service... I am done with their product in part and in whole.

    Strengths:Smooth, fast, reliable. Looks great.
    Weaknesses:Price. Difficult to clean.
    Similar Products Used:Deore.
    Bike Setup:XT,XTR Giant Terrago
    Bottom Line:This thing rocks! Compared to, say, Deore there is a minimal difference in shifting. If they're clean and new. However, when the crap starts to fly you'll see where your extra (a lot of extra) money went. In the dirt i had constant problems with Deore, often the thing simply refused to shift when coverd with mud or sand. When i cleaned it again, the problems were over. Not so with the XTR (RD-M960). When covered in mud mixed with pine needles (very nasty stuff) the thing didn't fail once. Ofcourse 'clean' mud and sand are even less of a problem. I use it with an XT cassette and at the time had a KMC chain (which is a disaster on XT chainrings with the mud/pineneedle combo). Now i use an XT chain which is better. Only thing i can whine about is the price (but you get what you pay for) and the fact it took me more than a week to get all the pine needles out (like i said:nasty stuff). It would have been easier if it was skeletonized, like SRAM XO. So that's the only downside i found so far, which is nothing since it doesn't affect the action. I think the main difference, compared to XT/LX/Deore, is durability, quality materials and manufacturing tolerances. If you're not a fanatic when it comes to riding, you're better off with the cheaper brothers. But if you are, and want top notch toys, XTR is the choice for you!

    Duration Product Used:2 Years
    Price Paid: $225.00
    Purchased At:LBS
    Strengths:Light and sexy.
    Ultra smooth and fast when dialed in.
    Shifts better (and much better under load) than forward-action/high normal derailleurs.
    Weaknesses:Very fussy about cable tension and contamination.
    Hard to keep dialed with regurlar cables under regular (ie dirty) conditions.
    Similar Products Used:'01 XTR rapid rise 8-speed rear derailleur
    '01 XTR high normal (regular) 8-speed rear derailleur
    Bike Setup:Baum Ristretto (custom steel hardtail), XT/XTR etc
    Bottom Line:A lot of people have been blaming poor shifting and a general unwillingness to stay in adjustment on the low-normal (or Rapid Rise) system. However, it's not Rapid Rise that's the problem, it's the Shimano 9-speed system. More gears in the same space = less room for error = more easily contaminated and damaged = poorer shifting on mountain bikes. My old 8-speed XTR rapid rise was the best derailleur I've ever owned.

    I've been struggling with on again / off again shifting from my XTR short cage for two years. It's silky smooth, quiet and fast when everything's dialed at least half the time that's not the case.

    The cheapest solution is to run a Teflon-coated or preferably fully-sealed, compression-resistant cable system like Avid's FlackJackets, and make sure your cable routing is nothing short of perfect. If you have down tube routing (hell, even if you don't), ditch the last loop of housing for a rollermajig or similar.

    With those three factors (careful routing, sealed cable system and rollermajig) taken care the derailleur has been a joy, and so far has held up in muddy conditions.

    Who should buy this?
    Anyone who loves Shimano's light, smooth action and is prepared to jump through a few hoops to get it dialed. For people with full suspension bikes or other rigs with funny cable routing it might not be worth the hassle, go straight to SRAM.

    Bottom Line:Rapid rise is the way MTB Derailleurs should have made from the very beginning. Being able to downshift on a climb without to much worry of breaking things under load only makes perfect sense. Your front Derailleur (left hand shifting) works like rapid rise why not the rear (right side as well).

    Took me one or two rides to become adjusted to shifting (backwards) I hate to call it backwards but I will to make a point. I will never switch back to standard rise.

    As far as shifting in general. Ive not had any problems with shifting performance. I always keep my bike tuned and cleaned ready to race. If your having shifting problems its not the Derailleur.

    Bottom Line:This derailleur has outperformed my expectations. I've only had it for a week or two now but it shifts accurately and quietly and the rapid rise is the way to go. Took me one ride around the parking lot to get used to it; on the trail today it was already second nature. Easy to work on the upshifts and downshifts alike.

    When the only notification of your shift is more or less resistance in the pedal, you know you have a good product :)

    Strengths:When new, shifts great to lower gear, even under load.
    Weaknesses:Because of the reverse spring system, it becomes harder and harder to shift to lower gears efficiently. After 6 months, I must have adjusted the thing 20 times, and then the LBS tried to adjust it. We both found that only after 6 months of just weekend use, the derailler no longer shifted to the lowest gear. What a waste of money. Don't buy the hype, Rapid Rise is not efficient at all.

    Bike Setup:04 Epic with XT package, crossmax enduro wheels, thompson seatpost and stem, easton handle bar
    Bottom Line:This system works great with the dual control shifters, but it (as so many others have said) always needs fine tuning. I rode this for 3 months and have already adjusted it (or brought to the mechanic) more often than I took my old XTR which I rode for 3 years. A long time ago Mountain Bike Action wrote a review which said let the people with the money to spend test the new products don't buy based on hype. I should have listened. Shimano needs more product development before this system is truly ready for the market.

    Just last week I jammed a 2 1/2" log through my wheel and destroyed my derailler, normaly I would have been pissed but this was the oppurtunity to switch back to the proven performance of Shimano's standard XTR derailler. I took it.
