Oden Posted February 8, 2012 Posted February 8, 2012 (edited) Hi All what Rear Derailer is better My first choice is a Shimano XT RD M770 Rear Derailer 9Spd Deore XT rear derailleur delivers reliable and precise shifting with a stiff and lightweight open design Rapid Rise.All-alloy construction leads to lower weight without compromising strength and durability.Four fluorine-coated link pin bushings make this one of the slickest shifting derailleurs on the trailsHigh rigidity wide outer link braces the pulley body to increase pivot joint rigidityMega9 compatible for use with 9-speed drivetrainsDurable sealed bearing tension pulley for low friction and smooth running of the drivetrainLow normal spring uses the spring to select lower gears, best suited to use with Dual Control leversTop normal spring uses the spring to select higher gears, best suited to use with Rapidfire shiftersRubber bumper reduces noise when used on non-conventional frame designs and my second choice Shimano XT 772 Rear Derailer 9Spd Shadow features a super low profile design that reduces the risk of damage from trail side hazardsSingle tension spring prevents contact with the chainstay resulting in a silent rideDirect cable routing prevents snagging from any trail side hazardsAll-alloy construction leads to lower weight without compromising strength and durabilityFour fluorine-coated link pin bushings make this one of the slickest shifting derailleurs on the trailsHigh rigidity wide outer link braces the pulley body to increase pivot joint rigidity resulting in a crisp shiftStrong return spring for a positive shifting feelSGS cage for use with triple chainsetsMega9, 8 & 7 speed compatibleDurable sealed bearing tension pulleyTop normal spring for use with Rapidfire shifters Edited February 8, 2012 by Oden
Caerus Posted February 9, 2012 Posted February 9, 2012 The cheaper one, as XT is XT. There must be a difference surley, as one of them is a Shadow derailleur
Mojoman Posted February 9, 2012 Posted February 9, 2012 I have the one with the silver cage, over 11,000km and no issues. I have replaced the jockey wheels once with the Tracx ones offered by CWC.
CAAD4 Posted February 9, 2012 Posted February 9, 2012 When I used to ride Shimano I had both and I could feel no difference, but I am no expert...
Bos Posted February 9, 2012 Posted February 9, 2012 not much difference in deraleurs.. BUT the day I got XTR shifters. .Deraleurs might be slightly stiffer and lighter the better they get, but If you want a fat change in performance get a XTR shifter..I smile everytime I shift a gear - also keep your cables clean
Oden Posted February 9, 2012 Author Posted February 9, 2012 (edited) Hi, TX ALL BOTH COST THE SAME R 699. I think i will go with the 770 as I have Aleavio rapid fire shifters. Edited February 9, 2012 by Oden
MoreTrails Posted February 9, 2012 Posted February 9, 2012 Aim for a medium cage, less chain slap, tighter chain quieter bike
Pusher Posted February 9, 2012 Posted February 9, 2012 Why go XT with Aleavio shifters? Rather go SLX and save towards better shifters!
Oden Posted February 9, 2012 Author Posted February 9, 2012 (edited) Hi I will be getting the XT Rapidfire shifters in March (20th or so) Edited February 9, 2012 by Oden
El Dodgius Bastardo Posted February 9, 2012 Posted February 9, 2012 Running XTR shfters with an XT rear dr, and it ROCKS. You can't go wrong either way, so pick the one that works for the colour scheme
Oden Posted February 9, 2012 Author Posted February 9, 2012 Running XTR shfters with an XT rear dr, and it ROCKS. You can't go wrong either way, so pick the one that works for the colour scheme Got a better quote on the XT than the XTR shifters and i have a silverback saturn the white one.
El Dodgius Bastardo Posted February 9, 2012 Posted February 9, 2012 You probably will get a better quote on XT than XTR...it's the nature of the beast. In terms of shifters, XT vs XTR is like Klusener vs De Villiers. Both get the job done, but De Villiers just does it with class
patches Posted February 9, 2012 Posted February 9, 2012 (edited) in my opinion the best Shimano 9sp RD is the Saint. I love mine and have never had issues with it. http://www.bicyclebuys.com/productimages/1010058.jpg I know it's not used in all applications... - it is super compact (ie. keeps out of the way of rocks),- it has a skid-plate for those times you do find the rocks.- The spring is super stiff, which keeps the chain nice and tight...- and lastly... just look at it! BTW, SLX is also a good route. Highly underated, but shifts well and nice and robust. Also no issues with that. My 3rd bike is running SRAM X0, so not allowed to talk about that under this topic Edited February 9, 2012 by patches
The Drongo Posted February 9, 2012 Posted February 9, 2012 Either is good. Shadow is cool. Just go for a Rapid Rise derailleur. It should be law for mountainbiking.
