Which frame is stiffer, a Specialized Tarmac or Venge?

Thanks

They're both ugly imo but the Venge looks beefier.

why do you care? you gona buy one?

Venge

I was looking at both last year and ended up getting a Tarmac SL4.

For BB flex and front-end stiffness, they were both plenty stiff and I couldn't tell the difference. Keep in mind that I'm not a big powerful sprinter, so YMMV.

The thing I immediately noticed was that the Tarmac isn't near as jarring or rough over chip seal, etc. The Venge rides like a brick. It's the roughest riding carbon frame I've ever ridden. The Tarmac isn't a Cadillac (I've got a roubaix for that kind of riding), but I have no problem doing 100 mile rides on the Tarmac.

I don't know about the Venge but my Tarmac feels pretty stiff to me. I love it.
