Unfortunately I wiped out today and snapped off one the Di2 shifters on my road bike. I'm trying to figure out which one I need to buy in order to replace it. Can anybody here tell me of there's a part or model number inscribed anywhere on these shifters so that I can reliably order the correct part? Just looking for some help in identifying the part that I have. If it helps at all, this is the standard groupset that came on the 2015 Cervelo S3.
Thanks in advance!!
