INVINCIBLE Tires: No

9 likes

Lovely backers,

Part of building your new favorite bike involved finding tires that would be beefy enough to eat curbs for breakfast without being fat and clunky. 

After months of testing, we found the happy medium:

These tires were inspired by cyclocross bikes. 

They're 32x700C, so they're wide enough to gobble a curb but not fat like a mountain bike's, which minimizes drag and clunkiness. 

We also made sure they'd give you the speed you need while having enough tread to give you traction when you're adventuring off-road and/or in foul weather. 

 Oh, and did we mention they're specifically designed to prevent flat tires? 

Bring it on, city streets :)

Next update, we'll give you the inside look at our brakes. 

In the meantime, enjoy what's left of 2015!
