Granite MK2 Frameset details

There are many many 20-inch wheels bikes over the world, but with thin tire. As a result, they are fast but not as comfortable as wider tires. So we are thinking how about build one extremely comfortable 20-inch wheels bike, and up to 20" 2.4 tires clearance can even support gravel riding. Now the dream has come true. Standard Granite comes with BSA 68 bottom bracket, and EBB version ( Eccentric Bottom Bracket ) is designed for internal gear system or single speed.
