As you would already know, for my Dahon Boardwalk, the colour scheme is mainly black and gold. Using black coloured components as the base, I add gold coloured bits here and there to make the bike unique. This time, I added gold coloured bits at some less-noticed areas. You can read about how I started sourcing for gold bling for my Dahon Boardwalk here.
One of the rarer coloured bits you can find would be the left crank cap on a Shimano Hollowtech II crankset. This is a black plastic cap that is used to preload the bearings in the Hollowtech II bottom bracket cups. If you want to make your bike unique, this is one of the parts where you can really make a difference!

Ta-da! Gold coloured crank cap! Super bling, I like it!
All the gold bits on the bike. Some parts are a different shade of gold, but no matter, still looks nice!
Another gold part that I got are the barrel adjusters for road caliper brakes. Again, these are uncommon parts to add bling, unlike common bits such as chainring bolts or bottle cage bolts.

At the same time, I decided to change out the gold coloured brake pad holders which I had been using. These gold coloured brake pad holders were installed a few months earlier. However, due to an issue with the function, I decided to change to special brake pad holders.
Gold brake pad holders. Even with the brake pad holder moved all the way to the bottom of the brake arm, the brake pad comes very close to the tires during braking, with a clearance of only 1mm.
Because of this small clearance, I don't feel at ease with the brake pad so close to the tires. If the brake pad is shifted out of place, it will rub on the tire during braking and rapidly wear out the tires. The brakes work, but I will feel safer with properly aligned brake pads that can afford more clearance. This time, function is more important than appearance.
I found these special brake pad holders that has the brake pads offset from the mounting bolt. Referring to the picture below, the standard gold brake pad holder has the brake pad located at the same height as the mounting bolt. However, the special black brake pad holder has the brake pad located below the mounting bolt. This effectively gives me extra reach with the brake calipers.
Given the same mounting location, the brake pad in the black brake pad holder is located lower by about 1 cm.
Not too clear from this picture, but with this special brake pad holder, I can locate the brake pads slightly lower on the rim, providing more clearance between the brake pad and the tires.

These are merely cosmetic upgrades, they don't make the bike faster or lighter. However, they do make the bike unique and strengthens the colour concept of gold on black.
In the next part of the Dahon Boardwalk upgrade series, I will be discussing an upgrade in SPD pedals. Stay tuned!
