I shouldn't have gone talking to the bike shop guys. :-)
Shimano Di2 on a carbon disc bike, tempting but expensive.
Why Di2 for me?
Well, I can't use my right hand/arm so all controls are on the left side of my handle bar.
For the last 5 years I ride an Apollo Transfer 40, kind of hybrid/MTB.
The rear shifting is done by a SRAM grip shifter, front with the normal two lever shifter. Both on the left.
The rear and the front disc brakes are controlled by 2 separate levers, also on the left.
So it s very cluttered on the left while the right side is empty.
That's where Di2 might come in.
Apparently it is customisable so you can program what ever each shifter needs to do.
However the cheapest I saw (and liked) is still $4,000: Merida Reacto 7000-E
Anyone else using Di2?
