The Ridley is a funny bike. It has a BMC fork on it that I put on because 1 1/8 to 1 1/2 forks are pretty rare/ I don't know if a Ridley Fork acts like this but there isn't a lot of trail. Bikes with significant tail you can hold by the seal and tip one way or the other to steer them while you're walking them. The Ridley barely reacts to this method. And yet it hardly wanders around at all. It will ride staaight despite bulps and uneven pavement that causes my other bikes to steer back and forth. This causes me to believe Dr. Richad Feinman. He said that no one really understands why bicycles work because bikes have been built specoifoca;ly to nullify each theory and the bikes have turned out to be rideable.
One of the most common theories is that the trail of the steering is the cause but my Ridley which has a very smooth steering obviously has very little trail and rides quite impressively. It handles so well that I have taken to riding it almost exclusively. The trail on my Colnago Master X lite is so fast that it takes some getting used to. It actually a bit scarry at first. It takes about 20 minutes of riding before you stop paying full attention to steering. The DeRosa Merak handles exqusitely but it wanders arould according to road surface as well. And it is using 32 mm tires.
So whatever Ridley has done, it is really well thought out.
