I would like to upgrade my nine year old custom sprint track bike (steel) with a carbon track fork...straight blade. Can anyone recommend a carbon fork that is track specific? What range of rake is recommended? Is it possible to convert to threadless, and is there a preference to either 1 inch vs 1 1/8 inch? I'm guessing mine is an inch. I've looked on web sites, and every fork is made for the rode.... with a drilled brake hole.
