Review: Perfect upgrade - Best deraileur for a 1x11 build
Review: Smooth Shifting - 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.

## Questions & Answers

**Q: What is the chain stabaliser, does this derailleur have a clutch ?**
A: The stabiliser is the system used to keep the chain from slipping off, or jumping the cogs. All dérailleurs claim the same. And yes, this model has a clutch, a little switch at the top of the unit which tightens/slackens the chain for maintenance.

### ⭐⭐⭐⭐⭐ Bike or Hike?
*by C***S on 10 March 2026*

I was surprised how easy the derailleur drop down was to fit. Once I’d removed the old one from the spokes of the rear wheel!! I thought I might have an issue with the gear cable as it had been caught up too, but it was intact and serviceable. I unscrewed the Allen bolt and then after admiring the workmanship that went into this marvel, I cleaned the chain which was clogged with grease and realised I might have been lazy in not doing good maintenance on it. It wouldn’t have taken much to have a stone trapped in a link or two!! Sorry, I digressed - that went into this marvel. I installed it with ease and made an adjustment to tune the positioning of the shift. Oiling the chain and also the cassette will be something which I will do in future maintenance tasks. Yes it’s a very good product for the money, but like me if you don’t maintain your bike you might have a few miles to get home, and who wants that! Eh?
