Shimano Deore M5100 rear derailleur, 11-speed, Shadow+, SGS long cage,Black

I had major gear skipping. Changed gear cable, purchased a derailleur hanger tool and also bought some spare hangers. I had reindexed numerous times but no go. Last thing to replace was the derailleur itself and that fixed the issue. These are solid derailleur and not overly expensive if they end up damaged!

Son managed to trash his existing one over some rather horrible curbs on his paperround. This set fitted perfectly on his bike and the build quality is brill. Works perfectlyl with his cassette already on the bike.Installation was easy, but it did require some care remembering which order to put things back together and how the chain goes on, but this is more cycle maintenance, rather than product related.It has now been on his bike for 10months with no issues, both to school, paper round and off roading at the weekend. Great replacement

Very long derailleur perfect for large cogs.gear selection is quick and smooth.

Fitted because my old derailleur wore out and I wanted this item so I could fit a cassette with a larger low cog (11-51). It works fine with my 10 speed drivetrain and SL-M4100 shifter. A good upgrade.

Price was decent, andd amid all the rumours of fake copies I cannot see any difference between this and an older one bought from a well established bike shop. Great delivery times and in original Shimano packaging. Excellent.

I am a bit of a one for looks and really like the look of this, but the observant will notice I have this fitted to a nine speed, I did look on the internet to see if this 11 speed would work with a nine, the answer seemed to be yes as the shifter determines the amount of shift, so I went for it.I have to say what I read was partly right, this does work with a nine speed and very smoothly as well, the downside is it only works with seven of the cogs, I could run it using the first seven or the last, I set it for the larger cogs, it's all to do with how much travel the rear mech moves to the amount of movement on the shifter.Is there a way round it?, yes fit a Sram X5 nine speed shifter it's a 1:1 and it works, I have nine gears now and still nice and smooth.I need to see how this goes longevity wise, the old Shimano Deore that I had fitted to this before had done thousands of miles and was at least 15 years old, it's done well with just replacement of pully wheels but was starting not to shift quite as well and as I have converted this bike to a mid drive e bike gear shifts need to be smooth to avoid damage, so far this is working well.
