olmobelgium, Congratulations on your bike. Sadly there are not too many Olmo owners in N. America as they were only imported here for a very short time span. Those of us that have them are quite happy with the quality and attention to detail.
If you don't have any experience working on a bicycle, this will be a wonderful teaching tool. Basically you'll disassemble it, clean, grease and reassemble, all the while replacing consumables like tires, tubes, brake pads, cable and cable housing.
