Thanks again for all the compliments!
Willier: I thought I'd ridden the Ultimate the most, however I've only ridden it the most so far this year. In total I've covered 6600 kms on it since I got it in March, and 7000 kms on the Aeroad since December.
The way the bikes are set up the Ultimate allows for a lower position. I can get lower in the drops and on the hoods because of a greater drop, and because of the 130mm stem I am more stretched out than on the Aeroad with its 120mm stem and slightly smaller drop.
The Aeroad feels somewhat more nervous and that requires just a little bit getting used to, but once I do, it feels natural, and the bike handles in a more agile manner and taking it around turns on steep descents is more comfortable. The Ultimate is more stable and is great in races.
As far as comfort goes I can't really tell any big difference. The Aeroad may feel a bit less stiff, but it is all pretty subjective. If I am going to perform a really hard effort I'll do it on the Ultimate because that's the bike I use in races, and my impression of the bikes may be skewed by that fact.
The Ultimate means business. There are no gimmicks and it's an easy bike to maintain. On the Aeroad I've had some troubles with the inserts that allows you to change fork rake. One of them came loose without me noticing, and the screw that holds it in place was stripped of its thread before I noticed anything. As a result I've epoxied the inserts to the fork. I wasn't going to swap them anyway.
