Review on ๐Ÿšฒ Shimano Rd-tz 31 Rear Derailleur: 7-Speed Hub Bolt Mount for Efficient Shifting by Mike Mitchell

Revainrating 1 out of 5

Very bad quality. at Derailleurs & Shifters

about a week after return date, same as the switch. Shifting was poor and very rough from the start, even after fine-tuning. Eventually the plastic support frame fell apart. Poorly designed and built with inferior materials. Complete junk/garbage. Don't waste your money on this model. Salvaged another derailleur from a broken bike, works great. (yes, all solid metal construction.)

Pros
  • Easy set up
Cons
  • Weight
