Brilliant simply brilliant. Was super easy to install and this would have been easier if my frame was ready for internal wiring. Crisp changes everytime and never miss a gear change. Very much looking forward to trying out the new syncro shift function.
A really great kit. Everything needed to upgrade my bike to Di2. The only thing you need to add to it is an adaptor to hold the battery in the seat post.
Shifting is very deliberate and smooth, I can never go back to mechanical.
Upgraded for my current Shimano 105 set and I have to say it's worth every penny. Shifting is flawless and quick. I would definitely recommend this to anyone who ask.
I bought this exact item from Merlin last year and liked it so much, with the transaction process as well as the item, so I purchased again for my second bike. I always wanted to do this once I switched to DI2.
Excellent service from Merlin. Just done my first 100 mile sportive with this kit and it really is awesome. Nice light touch to change gear and never missed a beat. Fantastic how the front derailleur automatically trims itself and you move up and down the cassette. Installation was simple and it hardly needed and setup as it seemed to work first time.
Received items as described. Cables were sufficient in length for a 56 cm bike. Great product and great service.
I ordered two of these sets for my bicycles: Giant TCR and Scott Solace 10. The best upgrade I've ever done to my bikes. Easy shifting, accurate and smooth. As posted here, only the parts to be upgrades are changed. For TCR Giant, battery can't be installed inside the seat post therefore, I had to order battery house from different site.
Having put DI2 on my TT bike a couple of years ago the whole fleet is slowly being converted. Cheaper than ever, reliable and never misses a shift. Will eventually kit all of my bikes out with it. Currently also have a tandem with DI2 on it as well as the etube cabling means you can simply extend the cables using a 40 or 41 junction box along the chain and plug and play the rest.
It's like a dream come true. Absolutely phenomenal shifting performance, without the constant maintenance.
I am sure Dura-Ace is a little better but for the price a Ultegra Di2 setup is awesome.
It is great to change from 6800 gear kit, high speed shifting, more easy to install. I can shift up and down when I use lower handle bar now.
DI2 is awesome. You have to try it!
Ultegra Di2 is a fantastic buy. Smooth, clean and quiet shifting - no more chain scrape and cable maintenance. Worth the money - it would be hard to turn back to mech!
Really impressed with the 2nd gen Di2 products. Hidden battery and downsized motors. Benchmark for shifting.
Great bit of kit. Could never go back to mechanical . Brilliant service by Merlin.
Got this because of sore wrists and problem with mechanical front shift. Simply brilliant. Lovely hoods. No sideways movement when braking. Can`t see how Dura Ace would be better. One little quibble - why not offer medium cage rear derailleur as an option?
Very happy with this upgrade to Ultegra 6870. The upgrade was supplied with the latest charger which now handles the software upgrades and settings, no need to purchase additional hardware!
First class kit upgraded from Ultegra and the difference in shifting is great. Any gear or combination and it works effortlessly.
Superb consistent shifting without the hassle of adjusting cables. Beautiful polished mechs. Couldn't resist Merlins offer price. Fast wel packaged delivery.
Faultless performance and easy to install
Cheapest price, well packing, fast shipping, awesome look, fast shifting, easy install, programmable controls, replaced from SRAM red, can't go back, two words "Must Buy"
Great quality, tried sram but gone back to Shimano for the ultra smooth changes
Great kit and great service! The Ultegra 6870 Di2 kit was exactly as describe and packaged well with all the original packaging. The kit came with everything needed to upgrade my bike to Di2. The shifting is awesome! The hoods feel great and the shifting is very quick and precise. Once properly tuned there is very little need for fine tuning adjustments unlike cable driven shifting. All I can say is if your on the fence about making the change to electronic shifting just do it! You won't regret your decision and it lives up to all the positive hype and reviews. My bike was originally built SRAM Red 22 and the frame was Di2 ready. Red 22 was great and by all means there was nothing wrong with it. The biggest reason for the change is consistency. With cable systems there is always that missed gear or tweaking the adjustments as your riding and triming the front derailer. With Di2 you always get the desired shift and auto front derailer triming. This was my first time using Merlin Cycles and I can say it won't be my last. They have the best prices and their shipping is very fast. I live in Oklahoma in the USA and was a little leery about ordering from overseas. From reviews like this one I took a chance and you've gained a customer for life. Product exactly as described, great prices and product arrived same week I ordered it. What more could I ask for! Thanks!
