What is my XYZ worth? How much is THIS worth? Value my...

Dear forum members,

I have recently inherited two (high-end) vintage road bikes from my grandfather and have yet to receive an accurate appraisal on the bikes, which is why I hope to be receiving some pointers from the experienced veterans in this particular forum.

The first of the road bikes has been gone over mechanically and is ready for sale, while the other is being looked over mechanically and will be put up for sale shortly.

Here's the data for the first:

1983 Eddy Merckx Professional Aero with complete 50th Anniversary Group (#2063)

Please view the over 100 full-sized HD pictures that can be found here:

Frame size: 51 cm (c-c)
Top tube: 52,5 cm (c-c)
Head tube: 10 cm
Stem size: 11 cm (c-c)

Frame color: red (with a mix of purple)
Tubing: Columbus SL steel (custom)

This is a custom order Eddy Merckx Professional Aero with a complete 50th Anniversary Group, save the down-tube shifters which were originally replaced because the ICS type are more ergonomic. The bike has been family-owned (one owner) since new and seen little use.

Following parts are guaranteed NOS:

• NOS Mavic S.S.C. Rims (front and rear, with original decals) with NOS 50th Anniversary Hubs (front and rear) and NOS 50th Anniversary quick release skewers (front and rear). The tubular tires have NOT been glued to allow the new owner to mount another pair of his liking if he so chooses.
  
• NOS 50th Anniversary toe clips
  
• NOS Regina Oro Freewheel, 6 Speed
  
• NOS Sachs Oro Chain
  
  

The bike was ridden using a pair of Mavic GP4 Rims with Campagnolo Hubs and Christophe toe clips, which is why the parts listed above are all new / NOS and have just been mounted recently for this particular sale.

As mentioned above, the bicycle features a custom order aero frame, featuring all-internal cable routing for the brakes and gears and custom metallic paint that fades into the chrome of the rear stays. Underneath the paintwork the frame is fully chromed. The paintwork ist 100% original with not one single touch-up or restoration having been undertaken on the whole frame. There are absolutely no dents, rust, pickles in the chrome, etc. of any kind on the frame. All the tiny little knicks of time have been protocolled extensively in the over 100 HD pictures.

All parts are guaranteed original and have not been replaced / modified. These include:

• original pair of hoods
  
• original bar tape and bar ends
  
• original Alfredo Binda toe straps
  
• original Selle San Marco Rolls saddle (date code: 1983)
  
• original 3TTT stem and Competizione handlebars
  
• original T.A. bottle cage
  
• original ergonomic, chrome-plated ICS modified Campagnolo Super Record Shifters with leather inlays
  
• original decals
  
  

The bicycle has been mechanically inspected and serviced by the kind and incredibly knowledgeable guys over at Cicli Scampi Zürich. They house an indescribable collection of vintage bikes and parts. Check out their webpage and online-store for some absolute masterpieces at:

The NOS parts were recently mounted for the first time. The drivetrain received fresh lube and the gears and brakes were adjusted accordingly. The bicycle is fully serviced and ready to use as-is.
The frame and group set show very very little blemishes and wear, which have been protocolled in-depth in over 100 full-size HD pictures that I have taken and can be viewed here:

I hope the pictures suffice. I have tried to show-case all blemishes and to take a picture from every possible angle. Further pictures can be requested.

What would be an adequate price for this road bike? I am looking to get a more accurate quote than I have received thus far.

Thank you for your time, interest and efforts!
