I weight 145, maybe 150 soaking wet.
I came from a FM015 ISP before this and I think this is just at stiff if not more, as far as I can tell. I mashed the pedals with my little legs and easily got to over 30 without any noticeable flex for me. Granted I haven't experienced "name brand" frames but it's as stiff as I can tell for my lowly wattage outputs and high cadence
I will say one thing I noticed was the amazing acceleration! I was like whoa!
This thing is a rocket. I was able to react to attacks on our group rides and caught up so fast I disrupted the train of riders that was coming to pass me. On another note it want's to climb really bad too! I really notice the difference in weight on climbs.
Still don't have a final weight but will soon!
Thanks, I like the look too as I have always lusted over cervelo's but didn't want to shell out that much for a frame. I love the way it rides, stiff and quick acceleration with my little experience (stated above). I too was looking at the new Allez frame but am really happy I went with this one. Honestly, I think they are both great frames and would have been happy with either! I just want to get out and ride more this year.
