I want to ask a physics-related question, I'm a male, 162cm, height 50kg/110lbs (I'm healthy, but too light!).
Right now I'm building a Surly Cross Check and I'm confused what wheels I should purchase. So I have two options: Alex DM18 (cheap) and Alex DH19(more expensive). They have similar inner rim width (17.9mm an 18mm). I really want DH19 but I'm little bit overbudget on other parts. I plan to use my bike for commuting and a little bit offroad. If I use the bike for offroad, do DH19 rims will stay true longer? Or because I'm thin, would using DM18 have insignificant difference?
Edit: the plan is to build an ss cx bike, no consideration of cassette/drivertrain
