Ole Ritter vintage bicycle, not much info found on the web on the bicycle except for the former Danish racing rider himself.
Bike top tube at 53cm having Groupset of Shimano 600 Tricolour with great condition, (still shinning):- stem, brake lever brake calliper, Shifter, crank, RD, FD, wheel set hub also a hyper glide cassette hub with Wolber rim. All in great condition except some slight scratches on the left of the brake lever and the crank arm. Seat post however just a Shimano but i am not sure which series it is. The drop bar is France make and the cable guide is label with MODELLE VITUS DEPOSE, which means pattern and design by Vitus. Bike came with road SPD pedal model PD-1056 which is a release in the early 1990.
Frame have internal route running under the lower part of the top tube.
The ride is consider smooth and consider light at +/- 11 kg , the weight probably came from the wheel set it self as it is a vintage wheel set with significant weight.
Got it with a good price and only need to replace shifter and brake cable to get it in good running condition.
Had seen only a few seller in Singapore selling this bicycle with same features but different group set.
