Mr Ian Chidgey Great upgrade for my bike. Smooth seamless operation and bang on accurate gear changes every time. The items arrived the following day after I ordered them so great service too.
SI Excellent value for Di2 upgrade - this is the second time I have bought this from Merlin as it's so good it's now going on my other bike!
Mr Andres The simplest conversion I have ever done. Everything fitted perfect didn't even have to make any adjustments shifting was perfect straight out of the box. Using the DI2 is a whole new riding experience and now I have get one for my TT bike as well.
Mr kelly I've been wanting to try di2 for a long time. After coming into some money I decided to make the conversion from mechanical ultegra. Installation was surprisingly easy once I found proper manuals from shimano and specialized. Check out si.shimano.com for dealer manuals with advanced installation info. My first response after a couple of rides is that I'm unsure it would have been worth it if I didn't have the cash to spare. I miss the feedback you get from a mechanical shift, and my old ultegra used to shift spot on every time. Only 4 stars as although it's an awesome bit of kit it isn't a 'necassary' upgrade.
Mr Tate With this price you are a fool to not upgrade to this set up. 100% shift change everytime, no more clunking or missed gears plus the added extra of improved braking.
Freelance mechanic from down under Everything you need is in the kit, including the control box, shifter cables etc. best value around. I've now ordered my second set! Do it.
Mr standen A great gear set!!! Was easy to fit and set up!!! Works a treat, and the best thing it was a bargin!! merlins service was great too!
Mr Coleman Heaven! Easy to fit; easy to trim (with some YouTube help!) Just loving it!
Mr Todd Custom bike build of a Cervelo S5 2012 has allowed me to pick the best parts available, these shifters are tried and tested and work brilliantly with faultless shifting even under maximum stress - I'm 250lbs so a heavy bike rider ! albeit on target to 200Lbs. The Di2 shifter Gear Kit is an upgrade option for most buyers wanting to switch thier existing setup whilst keeping an eye on costs etc Well worth the money Thanks
Mr Purcell Extremely happy with the Ultegra Di2 upgrade. Everything was as described and the well packed.
