Normal size range, so stock bikes should be fine.
Touring bikes are a niche product. You have REI Novarro, Trek 520, and Bruce Gorden BLT, and possibly Fuji. Discount sellers are unlikely to stock these.
Anything more is going to be a custom or boutique bike, like Rivendell , Waterford, or your local speciality frame builder.
HenryJames.com has a good index to custom builders.
