Replacement for my old one of the same type that died in a crash during a group ride. This derailleur works great, so far no need to go to 11-speed groupset. Shifting is crisp and quick. These days, no easy feat to find it online, though! Thanks Merlin for having it in stock.
Super slick shifting - was using 6700 shifters with an old XTR 950 rear mech which worked, but this mech is very light action. Also works ok with a 11-32 MTB cassette
Very good (as Shimano kit usually is), easy to fit and adjust, no problems at all.
I ordered med cage 6700 derailleur due to moving to 30 rear cog, fitting and tuning was very easy, followed the Shimano website instruction. Derailleur has been fitted now for two weeks and all is running very smoothly.
This was a replacement as I needed lower gearing for the alps, works as well as the short cage did. Clean and crisp shifting, what more can you ask for.
A nice upgrade from my old 105 derailleur, more accurate, lighter and precise shifting and always the best price from Merlin .
Beautiful bit of kit. Smooth changes (on 9 speed) and excellent price.
Great derailleur. Light weight, looks good, shifts are smooth and quick.
Purchased Two of these as they were on such a good offer from Merlin - upgrades for my Winter Bike and my Carbon Tarmac. Had them fitted and tuned they provide silky smooth indexing that I have never experienced before. Thoroughly recommended purchase and seller.
Fast delivery, best price. Replacement for broken 6600 version. Perfect operation, exactly as you would expect from Ultegra.
After my old Tiagra 4600 rear derailleur, Ultegra RD is perfect. The jockey wheels are made from good material and its good that Ultegra RD is not influenced by temperature like Tiagra RD. Thanks Merlin for fast ship and care.
Very happy with this product. I had smashed up an old Dura Ace 7800 rear mech in a crash and could not afford a new Dura Ace one. Decided to go for the more affordable Ultegra and would say it was a better derailleur than my old one - looks great, super smooth shifting and no problems so far. Highly recommended as a high quality yet affordable alternative to the top end kit.
Huge improvement in shifting compared to 105 (5700) even when used with 105 shiftlevers.
You know how good this kit is, shimano never fail to deliver
Upgrade from 105, shifting far more precise even though I am still using 105 lever, great price and service from Merlin
As usual Shimano have produced a great value piece if kit. Lightweight easy to fit and adjust with super smooth gear change. Top marks and highly recommended.
Envio rapido, bien empaquetado. 100% recomendable. el Ultegra es un gran cambio, preciso y suave.
Much slicker shifting than the 105 it replaced. Would advise anyone to invest that extra cash & go for the Ultegra over 105
Great! Super Crisp Shifting & Looks Great!
It's everything you hear around. Shifts great, and handles up to 28t sprockets with standard or compact chainsets. It is said that it performs as well as Dura-ace, but I haven't ridden one of those to compare.
Great smooth shifting perfect for 28 tooth sprockets. Upgraded from 105 well pleased !! Delivered next day GREAT SERVICE FROM MERLIN !
Excellent price, Delivered fast ! This was a replacement mech for an old Dura Ace mech that had seen about 5 years service, it went on the bike easily and immediately made shifting quicker and snappier. Very pleased with it.
This is a great bit of kit shifting is spot on set up very easy and looks great. It's super lite and would highly recommend it to anyone.
Beautifull derailleur and faster shifter
Great product, very fast delivery in Brazil
Best price and fast delivery, will certainly use again...oh,and the mech is pretty good too :0)
