Rated 5 out of 5 by Damolition Super upgrade
Got this to upgrade and replace my old deore mech. After setting it up, it has done everything i was hoping and more! I just wish I had got it sooner!

I replaced a rather old LX rear mech with this one - bargain price at CRC. Once I had set it up properly (ie indexed the gears and readjusted after the cable had stretched) the shifting was fantastic. No noise, no fuss, just a super smooth shift up and down the sprockets - effortless and instant. I am using XTR cables with the PTFE coating which probably helps, but I think the improvement is at least 90% mech.
This is probably the best upgrade I have made to my bike and worth every penny. If you are upgrading an older bike, as I was, then I couldn't recommend this product more highly.

Rated 5 out of 5 by Anonymous I replaced my old deore m591 rear derailleur with this one. What a difference! Really smooth shifting!

forget the shadow options of the XT rear mech - from my POV they are no where near as well made and strong.
I rode XT and SLX shadow for a couple of years destroying them very quickly.
I have had this one on my bike for 9 months - the shifting performance is second to none and it is still straight as a die - unlike the shadow versions which seem to twist out of shape very quickly.

I have this on my Mckenzie German mountain bike. Its a bit clunky changing gears if your pedling to hard, but apart from thats its a really nice, light and tidy derailleur

Rated 5 out of 5 by Anonymous Отличный переключатель
Оказался легче на 64гр моего стокового LX. Внешне понравился))
Переключает хорошо, пока ничего отрицательного сказать не могу.

Rated 4 out of 5 by Anonymous impressive
Just bought this to replace old bog standard derailleur that came on the bike and it has made an instant difference. The old (acera I think) had stopped shifting precisely but this one is extremely smooth. didn't take too long to setup, my only gripe is that it doesn't have a barrel adjuster. Once set up it does work perfectly but I would have preferred the option of a barrel adjuster so fine adjusments can be made later on.
