WARNING! THREAD JACK!

38/10 = 97 gear inches. With a 26x2.1 tire, 75rpm = about 22mph and 100rpm = about 29mph. If I were you, rather than trying to get a 10-tooth cog on there, I'd look at getting a 42 or 44 tooth large chainring.
What's the formula for those numbers? I'm sure I could use my wonderful math skills that I aquired in high school,but I just barely got passing grades.

END THREAD JACK.
