The auction is for both front and back (left and right) shifters and attached cables.

They are suitable for Shimano 2x11 speed Di2 group sets except 7970

They can be used on their own or in conjunction with your regular shifters for extra options.

More info can be found here

They are fully working but are used, they have some cosmetic marks / scuffs (see photos)

They are not the prettiest but do the job as they should

I am also selling more quality bike parts so check my other listings

Thanks for looking
