What is meant by try for fit?
Saracens are still OK, but the others have caught up in terms of value. The two bikes you mention are about the best for the money you can get - test them out?
Wharncliffe is great!
Doesn't always mean an increase in budget, some good options for that price if asomewhat heavier than a hardtail. New guides should be up next week for 09 bikes.
So where will you be riding?
