My recumbent requires a long cage shifter due to its long & convoluted chain path. This is a perfect replacement for the Shimano Dura Ace RD-7700, and a perfect mare to Shimano SL-BS77 Dura Ace Double/Triple Bar End Shifters. Simple to install, and very smooth shifting.

Easy to install , clutch is a useful feature. When set up properly the chain stays where it belongs at all times .

Ottimo deragliatore preciso e silenzioso

Cooles Schaltwerk. Funktioniert sehr gut mit dem Deore-Schalthebel. Ich benutze es in einem 2x10-Antrieb an einem HT MTB 27,5-Zoll-Bike. Kassette 11-42, Kurbel 26-36.

I put this on my vintage GT mountain bike as part of an updated 1x drivetrain. Works great! It shifts perfectly with very easy set up. Don’t make the mistake I did… I first tried to pair it with a 11-48 cassette but quickly realized it wouldn’t work, looked closer at the description, and saw that it maxes out with a 46t gear. No big deal though. Got an appropriate cassette and it all came together perfectly.
