This is why I bought a new derailleur hanger that had the main thru-axle threads on the outer piece. The thru-axle itself then tightens down the whole back end. The tiny little screw then doesn’t offer any structural support.

Hi! Has anyone built the frame with di2, and if so, how did you mount the battery?

Hey guys,

I ordered my frameset and its in the process of painting, in candy blue.
But I still have some questions while planning my build.

Did your frameset come with grommets for the exit ports of the brake hose? Meaning the holes in the chainstay and fork to prevent rubbung of the brake hose on the carbon.
Or did you buy Specialized grommets? Or use none at all?

Secondly: Does the frame come with di2 cable grommets? Or which ones did you source yourself?

How did the Di2-Users mount the battery? I read about just stuffing it in with bubblewrap, but is that safe?
Has anyone tried the SL7 Battery mounting grommets (S199900003)


Thanks for your input! Really looking forward to build up mine soon!

How do you mount the Di2 battery in the seat post?

After about a year with the Sensah Empire Pro 12s and an 11/34 cassette I’m just done with the subpar shifting and splurged 

If the C ring is the only thing holding you back, there are a few easy fixes to solve it. I bypassed it all together with a different compression ring that came with my handlebars (The One Pro). The Tarmac SL7 ring is another option at like $30USD.  Granted, I get that it’s super annoying to have to immediately replace a stock part to get the bike rolling, but that’s what I expect when you’re paying $700. I also immediately replaced the rear derailleur hanger because I think the stock one is unsafe but that’s just me.
