Skylark Posted January 7, 2019 Posted January 7, 2019 Slightly off topic chaps.....so I was looking at the same scenario. Xmas came and with it a voucher which I used to get the NX upgrade kit. I've installed and and am happy with it. To be honest I find the shifting, pretty smooth and silent and the lever action lighter than my previous XTR setup. This could be due to my immense strength build from "playstation/xbox thumbs" However has anyone had any issues with "trail chatter" from the rear derailleur? I find that over bumpy sections the derailleur is quite noisy. Would this be because there is no "lock out" clutch?Does it have a clutch at all? The lock out clutch I was referring to earlier is on some Sram clutches where you can lock the Rd down, which is handy when taking the wheel out or changing the chain, you disable that lock when riding though, so that feature has zero effect when you are out on the trails.
Butterbean Posted January 7, 2019 Author Posted January 7, 2019 What is MS, do you have a link to it?It's the same as mine, and will work just like the NX would work.
DieselnDust Posted January 7, 2019 Posted January 7, 2019 MS? As in micro spline? That's only for XTR 12speed SRAM dérailleurs don't have a clutch like Shimano dérailleurs. They don't need them as they are only intended for 1x use. The derailleur moves in one plane by design.The lock mechanism is just there to keep the jockey cage out of the way to make wheel removal easier as the jockey cage spring is much much stronger than in other brands dérailleurs. At all times the jockey cage lock must be off for the derailleur to work properly. As for trail chatter, what bike are you riding. Some rear sus designed do cause a lot of trail chatter

Might just have to setup the gopro on brackets and clamps to have a look to see whats going on.
Quagga Posted January 8, 2019 Posted January 8, 2019 Yip and with XD-R coming for road Shimano will never see my money again.... Ever.If I buy a Crank it will be from Stages but more likely I'll be using quarq going forward. Just sick of Shimano poor design and expensive locked in replacement parts. Sick of warrantying shifters and dérailleurs. SRAM and campagnolo make better products because they are not fueled by the arrogance of monopoly. If they don't build better parts they go out of business so they just build better equipment on every levelDont do it 1. No local support, you can not get it calibrated here if you ever need to2. Mine and a friends lasted 5years and constant issues3. Stages WORKS and WORKS AND WORKS
Quagga Posted January 8, 2019 Posted January 8, 2019 I am with D I D here... another way to do it is 46 - 34 = 12T50 - 36 = 14T Now 2 teeth dif might seems small until you change the chaing by 2T and see how big the difference is 0.74 vs 0.72 is hardly the same..The app I used is called calculator hahahaha really? 0.02 difference? No man.... 32/19 and 34/20 feel pretty much the same to me on the SS.... Are you arguing semantics or genuine gear ratios?

T-Bag68 Posted January 8, 2019 Posted January 8, 2019 https://www.cwcycles.co.za/product/sunrace12sp-upgrade-kit-1x12Thanks for doing this GrahamS2.. So if I buy this kit, then all I need is the Sunrace front blade ?
Quagga Posted January 8, 2019 Posted January 8, 2019 Thanks for doing this GrahamS2.. So if I buy this kit, then all I need is the Sunrace front blade ? No, all you need is ANY front blade that is narrow/wide
DieselnDust Posted January 8, 2019 Posted January 8, 2019 SRAM does have a clutch, even says so on the website, what they dont have an method to engage or disengage the clutch. EDIT attache picsram.JPGYa I saw this but when disassembling the thing all that's inside is a moerse strong spring and a roller ball bearing instead of a bushing like road dérailleurs. The "clutch" is just a strong spring.Hence if you use an oval chain ring it won't wear the clutch out

The bearing "grabs" to keep the chain tention

Apemanscolony Posted January 8, 2019 Posted January 8, 2019 I must say, im looking at getting the Sunrace setup, as its cheap and Sunrace is on the market for years on end. WOuld like to hear how its going after a week, 2 weeks and so forth. The front blade dilemma, is a bit each to their own. Why do u want top end? How fast do u want to go on top end? I have a 34 oval on my bike, 1 x 11, with the Sunrace 10-46 on, and it works great for me. Even if im going 50, im going to stay on 34. Im doing 34km/h avg on that gearing easy, and even can do a 45km/h on flats. Yes flats u can go higher and spin, but how many flats are there really, depending on where you ride. Depends on your riding style, where you ride, what you ride etc. Test all and choose the best option
Quagga Posted January 9, 2019 Posted January 9, 2019 Huh? 2 teeth doesn't change the ratio? 0.739 vs 0.72. 0.019 difference is negligibleSo why does it make such a difference to go from 34T chainring to a 32T? Espcially for climbing. I can not climb a certain steep section on my 34 but put the 32 on and there I go
