Meezo Posted July 27, 2016 Posted July 27, 2016 a little PM telling me more RE where you got that would be most appreciated!there you are, did order a few other things that aided in free shipping Mopkop 1
Hairy Posted July 27, 2016 Posted July 27, 2016 there you are, did order a few other things that aided in free shippingshot ... never looked at Merlin cycles before!
Meezo Posted July 27, 2016 Posted July 27, 2016 shot ... never looked at Merlin cycles before! if you not too hasty, mates were looking at doing a group buy, after i fitted the NX to my Trance obviously... i'll inform if you we're(they're) planning on ordering again! Hairy 1
splat Posted July 27, 2016 Posted July 27, 2016 It would be great if there was an SLX version of the new 11-46 cassette Hairy 1
Meezo Posted August 12, 2016 Posted August 12, 2016 Pricing is excellent! Merlin, stopped shipping SRAM to South Africa...
Headshot Posted August 12, 2016 Posted August 12, 2016 Bike discount.de can be cheaper and they happily ship here - even complete Radon bikes.  I think its worth getting XT an rear derailleur over SLX - the SLX item is far heavier due to abundant use of steel instead of ali and the XT cassette also weighs significantly less. Not sure about the brakes, but I doubt there is major weight to be saved there and the performance is allegedly on a par.  The new SLX crank looks better than the old one. Does it use a different BB as XT does?
robsc Posted October 12, 2016 Posted October 12, 2016 (edited) Anybody checked yet whether the new M7000 rear derailleur works with the old 10 speed shifter ? M670 Edited October 12, 2016 by robsc
Fisan Posted October 12, 2016 Posted October 12, 2016 Anybody checked yet whether the new M7000 rear derailleur works with the old 10 speed shifter ? Why would it? The ratchet / gear selector (sorry can't find the term now) only allows for 10 gear shifts. With the 10-speed SRAM shifters you could replace the ratchet to upgrade to 11 speed, but as far as I know you can't do that with Shimano... You will at minimum require 4 new components coming from 10x speed. shifter, RD, chain and cassette.
robsc Posted October 12, 2016 Posted October 12, 2016 (edited) Why shouldnt it ? The derailleur will move as many shifts as the shifter allows . I am just asking as I am not sure that the "ratio/yaw" that the derailleur moves will be the same as the old 10 speed SLXÂ Edited October 12, 2016 by robsc
robsc Posted October 12, 2016 Posted October 12, 2016 (edited) On the Mrs. bike I have a brand new chain and an 11-42 cassette (Sunrace 10 speed) running my old XT 10 speed derailleur (1 x 10). The problem is that to accomodate the 42 cog the B-Screw has to be turned in very far and the top pulley wheel while in the 11 up to 21 tooth sprockets is far away from the cassette. I know that the newer 7000 and 8000 series rear derailleurs have addressed this problem (I am running an XT M8000 1 x 11 on my bike) . Hence my question is would the new M7000 derailleur work on a 10 speed shifter , it will save me a bit of cash until I need to replace the cassette and chain with which I will then go M7000 everything  Edited October 12, 2016 by robsc
Fisan Posted October 12, 2016 Posted October 12, 2016 (edited) My understanding is that 11 speed spacing is slightly narrower than the 10 speed spacing. In such a case you might have some problems to begin with. But in any case, the 10 speed shifter will render your 11 speed RD to a 10 speed RD...which kind of defeats the purpose. If you are referring to running a 10 speed setup with a the m7000 RD...It might work, but I can't imagine that you will have the same smooth shifting as a normal 10x combo. Shimano 10x: 36t Cassette:  11-13-15-17-19-21-24-28-32-36TShimano 11x: 42t Cassette:  11-13-15-17-19-21-24-28-32-37-42T So your bottom range is similar, but again, spacing as well as offset differences might complicate matters. The question still remains why!?...  Okay now I see why... One suggestion is to check yourself? Using your M8000 RD... But it's a lot of time & effort and you'll probably have to redial to RD back on your own setup. My final suggestion is just to take the bite, buy an upgrade and sell off the old parts. Throw in some Sunrace components to save cash. It is not that expensive anymore (yet..?). Edited October 12, 2016 by Koei
robsc Posted October 12, 2016 Posted October 12, 2016 Thanks Koei , I am heading in that direction . Would just love to know if the system is "backwards compatible" . Shimano wont tell you as they want you to buy the newer stuffÂ
robsc Posted October 12, 2016 Posted October 12, 2016 (edited) Just read in another forum where a chap has used an XTR M9000 rear derailleur with an older 10 speed XTR shifter and he says it works flawlessly (running 1 x 10).

I was happy with mine for the last 18 months. I just changed to full M8000 setup with the 11-46 cassette. Shifting is very much better - light, slick and near instantaneous in all gears. Just beware, based on current Shimano specs from their website (possible error) the M7000 long cage RD is for 3x systems and is 10speed and still only designed for max. 36t big cog on the cassette whereas the medium cage RD can take 11-46 in a 1x system or 11-42 on 2x systems but is designed for minimum 40t on the big cog which means the top RD pulley might be too far away for a standard 11-36t 10 speed cassette. If it works with your M8000 RD it will work with the M7000-GS RD. Sent from my SM-G935F using Tapatalk Edited October 12, 2016 by JXV
robsc Posted October 12, 2016 Posted October 12, 2016 (edited) Yeah thanks JXV. I have the GS M8000 rear derailleur . Will also get the M7000 GS rear for her bike as well . Edited October 12, 2016 by robsc
