Review: Fits perfectly over the original that it replaced - 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

## 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.

### ⭐⭐⭐⭐⭐ Smooth Shifting
*by J***N on 12 December 2022*

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.
