great di2 upgrade

Posted02 December 2014
Yes, I recommend this product.
Pros: Good quality, Comfortable, Lightweight, Looks great
Cons: Expensive, poor fit instructions
Easy enough to plug in just unravel your bar tape, you'll need a di2 cable tool, take out the plugs in the spare sockets, plug the tri shifters in and away you go. Plug and play made easy. These come with two buttons, for front and rear gear changes. Not sure why anyone would want the more expensive single Button version? These are awesome. Just make sure you tidy up the cables under your bar tape and an internal routed clip on bars or tri bars. Only gripe is no real fit instructions, unless you've got straight extensions its fairly tricky to get a tight fit as you won't be able to get an allen key in to tighten up so need to force in tight and dont want to hammer them in and risk damaging your shiney new tri bars without them coming loose. Think I've got the hang of it but occasionally they come loose and need to unravel the bar tape to slacken up the cable remove the shifters to tighten them up. Bit of a pain.

Great product when adding aerobars to a road bike

Posted15 September 2014
Yes, I recommend this product.
Pros: Good quality, Lightweight, Looks great, easy to fit
Cons: Expensive
If you've got the compatible Di2 system these shifters will just plug into your regular shifters to give you the option of shifting from the aero position. They are the usual sturdy Shimano build quality.. They ARE a shade pricey though.

Plug and Play Ultegra 6770 Di2 10 Speed

Posted25 May 2014
Yes, I recommend this product.
Pros: Good value, Good quality, Comfortable, Lightweight, Looks great
I fitted the switches into the ends of my aero clip-ons, plugged the cables into the spare sockets on my STI levers and they worked perfectly!
Cables come with plugs and are the perfect length to run from the break levers to the end of the TT bars.
I love how easy these are to use and they are always spot on changing gears.

Di2 TT changers are fantastic

Posted11 May 2014
Yes, I recommend this product.
Pros: Good value, Good quality, Comfortable
The bar end TT changers matched with the brake lever changers gives such good control. The buttons give a very positive change and to me are much better than the road version which tries to duplicate the movement of mechanical changers. I think Shimano should use buttons on the road version.
