    S3Disc and D-Fly

    So, just got my S3 Disc with 6870 Di2 and I'm wondering about wireless compatibility with either an EW-WU101 or EW-WU111 and iOS. Shimano requires a DN110 battery so I looked into the seat tube to see what I've got and... there's no battery in there! In fact, I can't find the battery, though I'm assuming it must be somehow mounted to the 2 little bolts at the bottom of the downtube. Does anyone know what battery is in the S3 Disc? or if it can use one of the new Bluetooth wireless units? I know the SM-EWW01 will work but it is Ant+ only, so no iPhone. Thanks!

    Hi jeffhenc, You will need to remove your battery to verify which battery is used on your S3 Disc. Here's why - The current S3 disc shipping now uses the new internal battery (Shimano code - BT-DN110 ) and the battery mounting hardware as the S5 (Cervelo code - DI-BMNT-S5D). It installs through the bottom bracket cable guide opening. You can see the supplementary manual on the bottom of the S5 page here - https://www.cervelo.com/en-us/road/s-series/s5 However, The new Shimano BT-DN110 battery only became available a the end of June 2016, AFTER we started building S3 disc models (parts need to be ordered months in advance of launch dates) so dependent upon when the bike was made/ parts were ordered, it could have either the older or newer battery. Hope that helps!

    Download the E-Tube software and hook it to your bike via the USB-junction box connection. E-Tube will show you the exact part numbers installed in your bike. I've got the non-bluetooth D-Fly and the old battery, so no remote setup and no sychro shifting for me.

    Thanks for the reply. I had my battery out last night and I DO have the newer BT-DN110. Unfortunately lost one of the M3 nuts in the process so I'll have to hit the hobby shop today for another one. No Loctite on my bolts and while one nut was held securely in the recess in the battery holder, the other fell right out. At any rate, thanks for your help.
