I hope you don't think that carbon fiber under compression is somehow less "stiff" than aluminum. Neither compresses or bends at all under any force you could exert.
I'm running these right now.Indeed the tension seemed way too low. In the end, the guy was in 4th gear or something and the chain was jumping like a mf. Usually on the lower gears (i.e. 1-4) the chain should to be already quite tight.
@Ron Bez: I talked to a Specialized Turbo tech expert in Germany. He said that it would be possible to put a chain guide also in my bike but the drilling needed would mean that some sort stress tests are necessary to make sure the frame durability hasn't been compromised. Too complicated, I thought. Possibly also some ugly clamp attachmen could developed but even that could be difficult because the seat post tube is kind of edged.
About the tires. I would have thought the Schwalbes would be harder than the std slicks. But I bet they beat the slicks in traction. And faster, likely yes. What width are your tires. Are they these.

Narrow one's 700×35's. I ordered 37's and they sent the narrower one's. I decided to try them as I came from road bikes with really narrow tires, and I got Really cheap from Jet. They work really well for me. No flats through goat head season here. The speed and efficientcy as well as ride quality and handling are so much better, I couldn't believe it. I run them at the lowest recommended pressure, the roads I ride on are trashed. I started with 700×38 Marathons, and was so impressed with them I wanted to try one of Schwable's faster better gripping tires. These would be an great choice if you want to stay with the stock size

BTW Specialized has the tire I am using listed as recommend for use on the Turbo in my manual.
Sorry it's been such a hassle for you with the chain dropping, Specialized should have taken care of that on older bike like they have on the new ones.
Good luck, keep us posted.
I had (Link Removed - No Longer Exists) (48T) installed to my Turbo, after getting sick of putting the fallen chain back on about every 5 miles. I will post experiences as soon as I have them. Had the chain replaced as well. The bike mechanic claimed that the old chain was off sync with the new ring. Dont know about that, the chain only had about 2k miles on it. He was almost insisting on changing the cassette as well. The original chainring cover did not fit for some reason which was not clear to me. Altogether about 200$.
Marko,
I have a few questions if it is not too much trouble.
1. Did you buy your own interface to the bike or are you borrowing your dealer's?
2. Do you have access to the latest firmware files for each of the bike's systems? Are those the versions shown?
3. Is that the latest diagnostic software?
I ask these questions as I have very little faith in my local Specialized Service store. As I do not trust them, I am trying to find out as much as possible to make sure that any work they do, can be verified.
Thanks and regards, Frank
