Re: My first build. Need some advice and I have some questions.
I'll offer one caution on the Cranbrook: watch out for that rear hub. They are not very good.
I've had to rebuild mine 4 or times during this summer.
Other than that, though, the Cranbrook really is a good bike for this job. More stout than I'd imagined.
Though you might want to switch to a shock absorbing fork as well. A 'no suspension' set-up will beat you to death.
