Silvio’s Bike Components

As mentioned in the first page I bought all components by myself and built the bike from the bottom up. I started with this frame:

1 Material Aluminum Superlite Trekking Cross Double Butted
2 Weight 1’925 g
3 Wheel size 28″
4 Headset 1 1/8 “(ZS 44mm) semi-integrated
5 Bottom bracket housing Shimano BSA
6 Front derailleur 31.8 mm
7 Recommended fork travel 63mm
8 Saddle clamp 31.8mm
9 Rear disc brake IS2000
10 Seat support 27.2mm
11  Back wheel Standard quick release 135mm

As I started all the numbers and characteristics above were meaningless to me. Component after component I figured out what each row means.

Let’s start with the most obvious – 1 to 3: Material, weight and frame size. The most recommended material for the frame is steel. The general opinion is that steel is somewhat resilient and easier to repair. Since I got an aluminum frame we will see how much the general opinion is worth. Weight…. the less weight the better. For the wheel size, it is widely recommended to cycle with 26″ wheels through the countries we are planning to explore. Because of equipment for preparation. Only with those first three points, I realized quickly the frame is not the best for our endeavor. However, call me stubborn I still continued using this frame.

I never thought about how the handlebar or pedals are mounted. This is where point 4 and 5 comes into play. The headset is basically a ball-bearing which holds the fork. Maybe this is obvious for you.. but to me it was an astonishing moment when I realized there is an inner- and an outer diameter. The outer diameter has to fit my frame. The inner diameter holds onto the fork. Back in the good old times, the forks had a diameter of 1 inch. Nowadays 1 1/8 inch is widely used. Also back then the fork and the handlebar were two components. That is why we need spacers to fix the fork or move them around when we want to alter the height of the handlebar. See below all parts to put together the frame with the fork.

After I figured out which component would fit the fork, I got into another action. This time with the pedals. I learned that the crankset – this is where the chain roles over – is connected via a “bottom bracket”. My datasheet form above states “BSA”. BSA stands for (British Standard Cycle. This is a standard for the measurements of diameter (~34 mm) and width (68 mm).
