Mr Hudon Fast shipping and Great Prices !!!! Very Satisfied
Mr Romano Arenas Perfect
Mr Hide It is a great quality. The spring feels a little strong but it shifts very smoothly.
Bowen Works like a Swiss watch. Im enjoying the extended gear range
Mr McNamara Bought to upgrade from 10 speed Dura Ace. Excellent quality, super smooth and direct shifting. Coupled it with R9001 levers, very, very happy with the upgrade. The ability to be able to run up to a 30 tooth cassette with it is excellent, it allowed me to keep my 39/52 cranks for a bit of cost saving on the upgrade but still get a great range of shifting for climbing.
CARMEN Llega el paquete en perfectas condiciones. El material suministrado es el esperado ya esta montado y funciona perfectamente
Al Olby Very clean shifting, and handles a 32 sprocket no problem. I'm not a fan of the look, and it also looks weird when you look down at it while riding because the position of the body is further inboard to a regular rear mech. However it does what it says on the tin and gives very smooth shifting.
MITCHELL Really great price on one of the best new rear derailleurs out there . I love that it sits back and doesn't get in the way when you drop the rear wheel, not to mention it just looks cool.
Mr Chaves Barboza Junior The rear derailleur can also be used with a direct mount, making installation of thru axles easier. And the most important to me, who is a cyclist that like mountains but am tall and "heavy", is that derailleur 9100 enabling the use of Shimanos new 11-speed 11-30 cassette.
