Overview of components
Fork material
The fork is made out of steel, which is tougher than carbon in the case of an impact. However, it can add some extra weight to the bike.
Wheels size
When leaving the production line, the Midnight Special model has aluminum wheels. 650b wheels make a great choice if you want to sacrifice speed for comfort. However, they don’t perform so well when you go over bumps and obstacles.
Brakes
For your safety, it is important to have quality breaks on your bike. Surly Midnight Special has Mechanical Disc brakes installed. These brakes are also very popular, and a lot cheaper than hydraulic disk brakes. However, performance-wise there is room for improvement.
