San Francisco 21-Speed BLX components
Fork material
The fork is made out of steel, so, it can add some extra weight to your bike. However, steel is a pretty tough and durable material.
Wheels
When leaving the production line, the San Francisco 21-Speed BLX model has 700c aluminum wheels. These are the most popular wheels for road, aero, gravel, cyclocross, race, and gravel bikes. However, these wheels don’t perform so well when passing over obstacles.
