Happy

A great derailleur for the price, shifts perfectly and quietly and is totally silent while operating on all sprockets. It is easy to install with a just a few allen wrenches, I didn't bother taking apart the chain, I just disassembled the cage slightly to get the chain inside it. Adjusting was slightly more difficult. The only issue is that there are no paper instructions for installation and especially ADJUSTING it. It is essential to adjust the low and the high limits to align the upper jockey wheels and chain with the low and high sprockets, THEN just as importantly, when derailleur is on smallest sprocket remove ALL slack on the cable by pulling the cable tight when the cable attachment bolt is loose, then retightening the bolt, and/or by screwing the cable adjustment barrel until the derailleur just starts to move inward to the next gear. Maximum rear sprocket size is supposedly 34 tooth, and I found it best the adjust the B tension screw inward quite a bit (the one on the bracket that limits the derailleur front and back swivelling) to help the upper jockey wheel clear the larger sprocket (28 tooth in my case) better. Once installed and adjusted, it worked PERFECTLY every time.

Just got as spare but good quality recommend

My bike had an old Shimano Nexus system and it was time for a replacement. This one works responsive and every screw does its job to adjust every part.

Het werkt heel goed en zonder problemen

Boa qualidade
