Hi im new to bike building, I have a Brody Cretin 2010 and i want to buy new rims for it. The current ones are 20'' im not sure if those are small but i want to buy new ones. All i see really are 26'' rims so if i buy 26'' will i have to buy new spokes, new tires and tubes? also if i buy online do i have to add 2 to the ''cart'' or do they come as pairs. I was looking at these rims http://www.chainreactioncycles.com/ca/en/ns-bikes-trailmaster-rim-26-/rp-prod87935 and i was wondering if they would fit and what spokes i would need
if you are, yes you will need new spokes. Yes you will have to say "2" when ordering online. unless it says they come in pairs.
Also check your spoke count on the hubs to make sure they match the rims you plan on ordering. as for length. Time to learn the spoke calculator.. don't forget spoke nipples as well.
