The XT 12-volt battery can be used. As a replacement for the SLX version, there is now a speed RD version. No issue. It's important to note that they're both 12 years old. speed.
There are two types of passators: 1x12 for 51T and 2x12 for 45T, and I'd buy one of each.
Yes, I'm using it on a 10-inch screen right now. 51, with one extra as a back-up.
I'm sure it will, to be honest. But that's like asking if you can be pushed down the road by people on the outside of the car if you're sitting inside it. Yes, but it is preferable to purchase an older 7 or 8-inch model. For $20 on Ebay, I got a speed derailleur. These will work far better with a friction shifter and will cost you $90 less because they were designed to handle larger jumps.

This derailleur is absolutely incredible. Shifting is fantastic, and there is no skipping. br>br>A Shimano slx 11-speed shifter and 11-speed derailleur are used with this 12 speed derailleur. SunRace cassette number 51.
However, the item was damaged upon arrival. First and foremost, I installed the derailleur because my old one was broken and, as any mountain biker knows, I "needed" to ride; the broken piece was more of a nuisance than anything else. Inside the box, there was a separate bag for the broken lever switch part. (pic 1). It was clearly a broken piece, and I quickly identified the source of the break. I didn't want to have to wait another two weeks for a replacement. It shifts well once installed, and it arrived sooner than expected, to their credit. This, however, did not break during transportation. Was this an item that was returned but not examined? I dunno.
Precision, smoothness, and strength are all qualities that can be found in this product. It takes a lot more abuse than the XTR ones, in my opinion. The only caveat is that you must perform clutch maintenance, such as cleaning it once in a while and applying waterproof grease (instructions can be found on YouTube).
This is my second one (this one is for my new bike), and the first one I bought has given me 750 miles of trouble-free service.
My Kona's drivetrain was changed from 1x10 to 1x12. The xt derailleur shifts smoothly and performs admirably when shifting on an incline. I strongly advise you to upgrade.
YUP! SGS 1x12 XT Derailleur with a truly long cage! Thank you very much! You were the only ones who had it on hand. I can't think of anything else to ask for. It does exactly what it says on the tin.
My Deore derailleur was replaced with an XT derailleur, and the shifting is now more precise and crisp.
Shimano 12 speed is far more finicky and unreliable than Shimano 11 speed in my experience.
