Matching Chain Stay Length to Trail
This winter I resurrected the first frame I built and put a new rear end on it. In the process I added 1cm to the chain stays. I like long trail bikes and this one has a figure of 67mm trail. Yesterday I gave it the first flogging, and it seemed more settled at speed, meaning it felt very stable and needed zero input to hold a line. In the original configuration the bike felt more like a mix of a road bike and touring bike, but now it feels more like an all day go bike. Not a touring bike, but a "lets go fast today" bike. Not a race bike to rail corners, but a point to point get there quickly ride.
The chain stay length is 43cm, previously it was 42cm.
My mind might be playing tricks on me, but have any of you experienced chain stay length needs to match up with the trail to get a desired characteristic from a frame?
