Oh. It's perfect! Going to tell the store manager to order one for me. Many thanks thewanted! But now I'm wondering if I have the 220mm one. Mine seems much more than 15mm longer than the one in the photo.
I could but the battery has a notch in it that dovetails perfectly with the bottle cage to keep the battery snug. If I rotate it there's no more notch.
Here is the 160mm (i.e., the old one) range extender cable on my SL2. It's workable. I called Specialized Denver and there are no 145mm cables to sell me at this time. All the 145mm cables went with the S-Works bikes.
If you have an S-Works, I'd love to see what the 145mm cable looks like when...
