As in the pic (my bike) currently running Ultegra 6500 including hub set and BB.
I'm doing a rebuild from top to bottom on this and pushing for the 7.3 kg mark depending on the frame weight, but if its more than 1.5kg it seems impossible without spending huge and risking dodgy v weight in a few components.
Does anyone know about or is able to source info on this frame? It's a Nishiki/Releigh RC4000. Plush ride for an Al frame and rather whippy.
