That could cause brake reach problems in the other direction of course, but it sounds like maybe it's going to be a fixed gear, with maybe no rear brake at all-
OK interesting to hear about the Schwinn,a good one,that conversion comes-up sometimes.As far as the OP,I thought of a couple/few possible scenarios too,I shot from the hip in answering,I used a dis-similar make once it once.
