Santa Cruz Bronson Frame

The MX configuration—a 29-inch front wheel paired with a 27.5-inch rear—is designed to give you the best of both worlds. The larger front wheel rolls over obstacles and maintains momentum, while the smaller rear wheel keeps the bike agile and easier to maneuver through tight, technical sections.

Yes, the frame includes a flip-chip located on the lower link. This allows you to make subtle adjustments to the bottom bracket height and head tube angle, letting you fine-tune the bike's handling to suit your riding style or specific trail conditions.

The Bronson uses a BSA threaded bottom bracket. This is a widely preferred standard because it is reliable, easy to service, and generally quieter than press-fit alternatives.

Yes, the frame features an integrated 'glovebox' in the downtube. It provides a secure, rattle-free space to stash essential tools, a spare tube, or a pump, keeping your pockets or pack lighter.

The geometry is optimized for a 160mm travel fork. Using a fork with this travel ensures the bike handles as intended, balancing climbing efficiency with aggressive descending capability.

The internal routing is designed to be clean and protected, which helps reduce maintenance over time. While internal routing generally requires a bit more patience during initial setup compared to external routing, it keeps the bike looking tidy and prevents cable rub on the frame.
