Room for a large volume tire so you can go farther, faster.
Designed from the ground up. We were tired of using off the shelf components to build our frames. We invested in designing and sourcing our our parts to build a better product.
Larger diameter bottom bracket allows us to tailor the ride and to hide unsightly cables.
We have a size chart here for the Gibraltar model with all of the XY measurements to help you find the perfect fit.
