Understanding Bicycle Frame Geometry
Understanding the Steering The front end of the bike is a bit complicated but we can work through it. There
Increasing the fork rake makes steering faster.
Fork Trail (Fork Offset) The product of the head tube angle and the fork rake is the ‘trail’. This is
Touring bikes have a long wheelbase due to a combination of a slack head angle, long fork rake and long chainstay length.
Chainstay Length One of the more important measurements on a touring bike is the chainstay length. A longer chainstay length is
it’s best to compare bikes based on their stack and reach measurements if you can.
Effective Top Tube Length The effective top tube (ETT) length is the simplest way to determine a bike’s size. That
