Colnago Nuovo Mexico Bicycle Restoration (Part 8)

Colnago Nuovo Mexico Bicycle Restoration

Welcome to part 7 of my Colnago Nuovo Mexico restoration. In the previous parts I have discussed the following parts of this restoration;

Test Ride – The Big Day has Arrived.

Now that the bike has been built, all that remains is a quick test ride before I finish the build by wrapping the bars with bar tape. I always ride the bike before wrapping the bars just in case the brake levers need to be repositioned for some reason.

It’s always a weird feeling riding a bike you have just built on it’s first ride. In the back of your mind you’re thinking will the wheels be OK, is the frame solid (will it collapse under me), did I forget to tighten a bolt somewhere? So I always start in a quiet side street and ride at a slow pace until your confidence grows. Yes, the brakes and steering work, the wheels and frame are just fine. All those original fears were unfounded, the bike is solid as a rock.

Then you start shifting of the gears. It’s fairly typical some adjustments will be required; tension the shift levers and adjusting the derailleur limit screws, but within a short period, the bike is cruising the streets with smooth gear shifts and a nice quiet ride EXCEPT the front brake that squeals when you stop.

This is a common problem and I had the exact same issue with the Campagnolo Super Record brakes on my previous Colnago build. This bike has new brake pads and rims, but the brake pads definitely need some toe-in to stop the squeal. Please check my article how to fix brake squeal on a vintage bike. The method used for this situation was to bend the caliper arms using adjustable spanners to create the 2-3mm of toe-in required to stop the squeal. I added the toe-in very gradually and test rode a few times in between until I reached the right amount.

It is a little tricky to see in this image, but the front of the pad is touching the rim on both sides and the rear of the pad has a 2 to 3mm gap from the rim. It is also important to make sure that the brake shoes are reinstalled in the calipers in the correct orientation so the pads do not get ejected under heavy braking. The whole process took about 1 hour (taking my time) and I suspect it is only required to be done once. Definitely time well spent.

The lever and saddle position all felt good, so last step is to wrap the bars with bar tape.

Wrap the Bar Tape

Having test ridden the bike and happy with the location of the brake levers on the handle bars, it was time to complete the bike by wrapping the handle bars with some white bar tape. I’m using Fizik Classic Touch Superlight 2mm bar tape which is not vintage but has a classic perforated leather look with a hard wearing exterior.

I’ve used Fizik Superlight 2mm bar tape on a number of different bikes. It is not super stretchy so it is a bit harder to apply than the materials used in other types of wraps like cork. Always give the bars a good clean to remove any old residue before starting.

I’m not going into the detail of how to wrap handle bar tape as there is plenty of pages on the internet discussing the many different methods that can be used. I only apply handle bar tape once every year or so, so I don’t consider myself an expert and I think it is a bit of an art form. Trying to get a professional even finish requires some patience and practice. I basically re-wrapped sections of each side multiple times until I achieved a finish I was happy with. Wrapping the second side is always quicker than the first as you know what to expect.

When using a white bar tape, it pays to do your homework by reading reviews about the ease of keeping it looking white. My research uncovered this bar tape which can be kept white with a regular wipe down and some care. Here are a few tips;

  • Put a towel over the handle bars when working on the bike so you don’t touch the bars with greasy hands. As vintage gear levers are not integrated into the brake levers like modern bikes, there is little need to touch the handle bars when working on a vintage bike.
  • Don’t use brand new cycling gloves (with black dyed palms) on white bar tape. I made this mistake previously and the dye from the gloves stained the white bar tape and cleaning the tape did not return it to the original white finish.
  • Start each ride with clean hands and regularly wipe the bar tape with baby wipes or isopropyl alcohol.

The Fizik bar tape comes with short pieces to cover the brake lever clamps. I fitted this piece to the rear of each lever and used a wrap of black electrical tape to keep it in place (step 1). I then wrapped the tape in an inward direction and finished off the tape with another wrap of black electrical tape (step 2) before covering with the Fizik finishing tape (not shown). Lastly I fitted an aftermarket Colnago bar plug (step 3).

My only gripe with this bar tape is it is not perforated the full length of the tape. About 8cm at either end is plan white bar tape with no perforations. This effectively shortens the bar tape by some 16cm, so you need to get the spacing just right if you want the perforations showing from start to finish on the bars.

Note: The internal diameter of vintage bars is smaller than modern bars. Therefore the Fizik bar plugs are too wide to fit inside without some kind of modification. The solution is to buy a set of aftermarket bar plugs on eBay which are available in a wide variety of styles and add a nice detail to the handle bars. I chose these Colnago branded bar plugs which are available in a variety of colors. They are easy to fit and secure the bar tape very nicely. I expect they could be re-used when changing tapes if required.

Fit the Biddon Cage

The last item to be fitted to the bike is the Elite Ciussi bottle cage. This is the alloy model with 2 x yellow and gold trimmed buttons to hold the biddon firmly in place. Elite sell a variety of these style of cages. My Colnago Master is fitted with the Inox steel version. I think the cage suits the build nicely with the colours matching the Colnago decal.

These vintage Colnago frames only have one biddon cage mount, so you’ll need to refill your bottle on longer rides. Not a problem if you have a team car on your ride.
