As with anything from Shimano, it does exactly what it said in the description. Delivered next day, fitted in 10 minutes and works faultlessly. Never heard of Merlin cycles until I googled for this derailleur, was the cheapest by some distance. Will use Merlin again!
Smooth shifting from Shimano. The SLX may not be the best in their range however one can't complain. As good as some of the so called better gear on the market at a much better price.
Great shifting. Smooth and precise. Little to no chain slap.
Great value, provides good shifts just as any XT derailleur. Only con is it is slightly heavier.
Excellent quality drailleur, very accurate gear changing and easy to set up. I recomend this product to anyone requirng a replacement
