Custom Bike
It's expensive, and the price/performance ratio is low. The benefit you get is probably marginal vs the investment, but why not.
It will be your bike, made for you and it's euphoric.
Why Custom Bike Frame
The basics about geometry (chain stay, wheelbase, fork angle) of custom build are fit to your body geometry.
The comfort on your bike is primarily determined by the contact points; handlebar, saddle, pedals.
The main advantage of a custom frame is that it is built to fit your geometry and not the other round. Furthermore, you can have exactly what you want on it.
How to Build Your First Custom Bike Frame?
1. Decide on the type of material you want to use for your bike frame, Steel or Titanium.
2. Decide who will be your bike builder, Cherubim, and Mosaic
Types of Bike Frames
- Steel, most classic frame material, has been used by frame builders.
- Flexibility of the material to bend and shape.
- Adaptable material caters to cyclists' most demanding needs.
- It offers excellent ride quality.
- Durable, easy to repair and maintain.
- Titanium is the strongest, and most expensive frame materials.
- It rivals aluminium in weight and is as comfortable as steel.
- Titanium frames are very costly to produce.
- Hard on metalworking tools, requires specialised titanium welding rod.
- Process must be done in a controlled environment.
