For the sauce: In a small bowl, whisk together the vinegar, tamari, chili paste, ginger and 1 tablespoon water. Set aside to let the flavors marry for about 10 minutes.
For the rolls: Meanwhile, in a medium bowl, toss the rice noodles with the sesame oil.
Fill a pie pan with warm tap water. Working with one wrapper at a time, soak the rice paper in the warm water for about 30 seconds or until pliable. Lay a few pieces of cilantro and basil across the center of the wrapper. Top the herbs with some crab, followed by some of the red pepper and cucumber. Top with approximately 1/3 cup of the dressed rice noodles. Roll the edge closest to you over the filling, pulling tightly. Fold in the ends and continue to roll to seal. Store on a tray with a damp paper towel. Continue with the remaining wrappers and filling. Serve with the dipping sauce.
