Hi,
As the thread suggests I'm trying to build up a race bike. I've been told my son needs an "Expert" size but unlike road and mtb bikes I've built, I'm a bit daunted by the fact that certain parts come in different sizes, so sourcing them may be more difficult than I thought.
As a guide is it just the forks that would need to be of an "expert" size or am I going to have my work cut out with everything?
