Can anyone help highlight the differences between the 381 and the 361 for me?

I understand that the 381 has some shaped tubing and seems to be touted as stiffer, but what does this really mean? how do each of the bikes compare in stiffness and comfort with other similar bikes like the trek and colnago offerings.

I built a 381i for my brother. He also recently had a C40.

The 381i is somewhat stiffer than the other frames in the LOOK line. Part of this extra stiffness is due to the externally butted shaped tubes of the front triangle and part is due to the way stiffer front fork. My brother said that the 381i is a little bit "rougher" feeling than his late C40. He thought they were about the same stiffness in the BB area. Plenty stiff!

The 381i would best be described as a no nonsense race bike with a lot of technology.

The 361 should be a tiny bit "softer" than the 381i. I wouldn't worry about that unless you are a monster big guy like Cipo.

I have both, although the 361 is just a frame now, since I put all the parts on the 381i.

The 361 has round tubes on the main triangle. The 381i has shaped tubes, not round, and they are externally butted.

The 361 has normal rear dropouts. The 381i has moveable dropouts, so you change the wheelbase.

The 361 uses HR carbon fiber. The 381i use HM carbon fiber. HM is stiffer and lighter.

The 361 uses a 1" steel steerer tube with an aheadset style headset. The 381i uses a 1 1/8" carbon steerer tube with a hidden headset.

I think I covered all the differences. Anyway, they ride pretty close in terms of road feel. The 381i may be slightly stiffer, but it isn't like you throw a leg over it and go "Wow, what a difference." Although the 1 1/8" steerer tube did make a big difference.

I used to ride a Trek 5200. Close in terms of stiffness. But the road feel is completely different. The road seems to disappear with the Trek. Some people like it, some people don't, it never really bothered me.
