A Sekai 2700 limped in the back yard last week, equipped with Superbe Pro RD and shifters, original Suntour Vx front derailleur, Diacomp G, Sugino cranks and bb, Tange Levin hs, with junk Normandy hubs on 27" Wolber Super Champion rims.
The brakes will be replaced with Royal Gran Comp aero levers and calipers, the derailleurs are now Cyclone, the wheels will be chunked and 700 wheels will replace the current offerings, the bars I haven't decided yet to replace but probably will. The hs and bb cleaned up and roll smoothly. I will replace the 42 tooth chain ring and a freewheel for some hill friendly gearing.
The Sekai 2700
The RGC calipers will work with the new wheels, but I will do a slight mod on the pads to increase my reach.
