Drilling a Ti Frame for Di2?
 

Hi all, can you give me some thoughts on doing this? Who can do it, is it advisable?
Thanks!

no matter what
 

my guess is there will not be room for the wires to get past the bottom bracket coming from the front of the bike.

the perfect situation for ETAP. try it, you'll like it.

Thoughts? eTap

Unless you're running a 30mm spindle in a BSA 68mm shell, there will be plenty of room for the wires to go past the BB spindle.

You need three holes, one for the FD wire, one for the RD wire, and one for the entry point.

Litespeed has the best solution, IMHO. See the pic below where the headtube cable stops can be removed to open a port for the Di2 wire. If I were drilling a hole up front, that's how I would do it.

In the back, you could probably just have the wires exit the bottom of the BB shell where the cable guide screws in - tape the rear one under the chainstay to run it out the back and the front one just tucks up behind the seat-tube. Or have the RD cable stop shaved off and a hole drilled there so you can feed the wire down the inside of the chainstay and out that hole.

Good luck!

great explanation

As for "who can do it" - try TiCycles: https://www.ticycles.com/services#retrofit

They list Di2 retrofit as a service, and Dave Levy (the guy behind it all) has been working on titanium longer than most.

That frame is an interesting one -- I think it's a Litespeed Vortex front end with some retrofitted monostay in the back.. Or else Ti Cycles got ahold of the same tubes that Litespeed was using in the years before the T1SL came out.

Good stuff gang. I have a good set of Di2 I could use.

Depends on the frame. My EPS wires had no problem getting by/under my BB on my Merckx.

And, just for info..not titanium but I think more forgiving..I drilled the holes for EXTERNAL battery EPS into my knackered Merckx MXLeader..Been riding it since Feb 2014..no issues.

Yep. He is the person I contacted for my retrofit. The prices are quite reasonable as well.

Anybody with the correct drill bit can do it. My buddy drilled his Ti Warbird for Di2 and it worked perfectly.

When you go through the bb shell make sure there is room where the drive side bb cup threads in and the vent hole. Also the grommits the Di2 comes with are for thicker material than a ti tube, they work but are loose fitting. Jagwire makes ones for thinner tubing and I believe they use a different drilled hole diameter.

If you choose to do this tonight, perhaps after a few 7&7's, please post pictures.

People are so precious about stuff. I can't imagine how this could possibly be problematic.

Buy a nice new carbide bit for it.

This made me chuckle!

DRILL! DRILL! oops...

They forgot the head tube and handle bars Ha Ha
