How to measure crank / chainrings size BCD

How to measure Bolt Circle Diameter BCD ?

Bolt Circle Diameter or BCD is the diameter of the circle that goes through the center of all of the bolts on your chainring. On bicycle chainring this dimension is usually measured in millimeters. It is critical to know the BCD of your crankset when you are selecting a new chainring for your bike. In many cases the BCD is printed right on the chainring, sometimes it is stamped or engraved on the back side of the chainring.

If it is not labeled on your chainring you will need to measure it. On a chainring with 4 bolts the BCD is the distance between two bolts across from each other. Alternatively you can measure the distance between two adjacent bolts and use the table below to determine the BCD.

Classic methos how to measure BCD is :

Chainring with 5 bolts -> distance (mm) between the two holes X * 1.7
Chainring with 4 bolts -> distance (mm) between the two holes X * 1.4

Alternatively at this slow and tedious measurement you can print this template (file .pdf)

Pdf file that you have to print without editing, making sure that your print settings do not reduce or enlarge it. You just have to put your chainring on the sheet, make the holes match and read the number, easy!

Postmodern Bicycles – Modern Parts on Classic Frame

Colnago Postmodern Bicycles – Modern Parts on Classic Frame

Imagine combining a classic steel frame with a modern groupset. This is what we call a ‘postmodern’ bicycle. I’m not sure this term exists but let’s call such bikes this way. At least it gives us an impression of being intellectual. Anyway, tell us what do you think about such combination?

Here we present the last OLDBICI Postmodern: Colnago Master Olympic Art Decor with Campagnolo Chorus 10s group

The advantages of postmodern bikes are:

  • Steel frame, much sexier than carbon fibre one
  • Efficiency and comfort of modern shifting
  • Safety of modern brakes
  • Lightness of modern wheels
  • Cool and Unique look
  • Lightness: you can easily achieve weight under 8kg with a mid-sized steel frame ex. made of Columbus SL or SLX steel tubes and Campagnolo or Shimano Dura-Ace groupset and other lightweight modern components…
  • Stiffness and great feeling of riding a steel frame
  • History and real craftsmanship behind the frame combined with modern technologies
  • And the value is very stable and rather increasing than falling (it’s a classic steel frame ;-))

So if you are looking for a postmodern bicycle, contact us if you want a custom-built road racer!

 

Campagnolo Tool box Tool kit

Our Campagnolo Tool box Tool kit is used and shows some light signs of use.
The tools are all still in amazing condition. Most of the tools show hardly any signs of use, they seem like a new never used. All taps and cutters are in excellent conditions.

We ship this wooden toolbox (weight 21kg) in two separate packages, one with just the empty wooden box and one with all the tools wrapped in paper and pluriball. Otherwise the tools could damage the inside of the box during shipment.

Campagnolo 50th Anniversary Groupset

The 50th Anniversary Groupset Campagnolo is a beautiful bit of engineering and production the like of which you don’t see today. The style and design of the components is hard to match and no modern components seem to have the same soul of these components.
That’s not to ignore the undoubted quality and functionality of modern groupsets but they just don’t have “it”.

Please note if there is anything incorrect in the below please let me know, I am always happy to update this page with more information.

This group was released in 1983 to commemorate Campagnolo‘s 50th year in business, this was also the same year founder Tullio Campagnolo passed away.

In the region of 15,000 of these groups were made.

Group #0001 was retained in the Campagnolo museum, and #0002 was presented to Pope John Paul ll. They all came with a numbered “membership card”.

The group was based on the Super Record and Cobalto group of the era and was top of the range, with some significant extra touches. Most pieces were marked by a 22 carrot gold logo with a raised/textured Campagnolo shield logo. All pieces contained an engraved signature of Tullio Campagnolo, and a special “50th” logo.

The group was supplied in a nice carrying case has a 50th logo printed on it in gold. The zippers on the case were sealed and an inventory tag detailed the contents. A close up of the seal is shown in the below gallery.

I have only one group for sale with the bag unopened NIB
