For those who have a Gunnar Sport, Ebay has Bontrager Satellite Plus forks for $50. It is the more streamlined fork that weighs around 560g with 335 steerer tube. It takes standard/long reach brakes and has fender eyelits. It only comes in the 45 rake and Dave Hellekson says that a 50 rake is more appropriate for the Sport due to the 385 axle to crown height.
With a 45 rake and higher axle to crown height, I assume the Sport would steer a little slower and increase the trail.
Either way, for $50 it is an another option.
