I haven't tried it, but I wouldn't want to run them because of the aero penalty you'd suffer with them on (I have a 5.2, same frame style, different carbon). I think 25c is probably the best balance between aero and comfort.

Thank you for your answer. What kind of wheels are you using? The bontrager aerolus are blowing up the tyres a little bit.

Zipp 404's. They make 23's plump up to almost 25c. I'll let you know how the 25's turn out when they arrive next week.

Madone 9: 28 Conti GP 4 seasons fit with plenty of room to spare on wide aeolus clincher rims.

super wide 30 strada biancha tubulars fit but lack a reasonable amount of clearance for road debris.

28mm Continental Grand Prix 4 Season is identical to 25mm in width but only heavier. Continental is aware of the mistake from their end and will release new batch in the near future.

Totally. That bike would be impossible to pedal with all the drag from 28's.

I'm running clx64 with 26mm sworks turbo pro in the rear on Madone 9. Balloons out to just under 30mm, Has plenty of clearance all around.

It depends... On the quality of roads mostly running on. The dissadvantage of increased drag with 28c might be smaller than what you gain with decreased rolling resistance on lower quality road surface with 28c's.
There is still a good option to opt for 25 on front and 28 in the rear. So you get the advantage of beter rollign resistance, increased comfort and pretty much unaffected aerodynamic drag.

I think that, 28c tire is too much on road bike.
And chainstay clearance is not cover to 28c tire.
And if you use the 28c tire, brakes also not covered.
Which brakes you using?? Please let me know.
I try to 26c tire, but zero gravity brakes covered maximum 25c tire.
