Thank you guys for responses. I'm just going to ride out with what I have.
Should have asked about my wheelset from the beginning as well -- forgive another silly question. I've got the Shimano WH-R500 wheelset that came with my bike. It has 24 rear/20 front spokes. Now, I've already had a problem with one of the front spokes coming loose and I ended up replacing it and using loctite on the new nipple. My question is this less than the number of spokes necessary for touring? I know that sturdy wheels are good to have -- the bike will be carrying a load of ~260 lbs rider+cargo. Once again, hoping not to replace what I have.
