Hello All! I have recently purchased a used Dahon 2005 Helios SL. However, the Rolf Prima™ Accel wheels did not comes with it? I understand the wheels are no longer in production from Dahon. Does anyone know where I get a lightweight substitution besides the Kinetix Pro S wheelset? Or would it be a good opportunity for go for 451mm wheelset? My goal is both lightweight & speed if possible.
