BOMMA ST 29" The all-new Bomma 29 stays true to the original formula that made it a favourite in the culture, but now comes upgraded where it matters most. We’ve fitted a powerful Shimano MT200 hydraulic rear brake for improved control at balance point, switched to a freewheel rear hub for ease of upgrades and added integrated peg mounts to the rear dropouts so you can push combos without damaging rear axles!Built around the same proven steel frame and wheelie-specific geometry, the Bomma steel delivers a huge balance point, predictable handling and the durability to take daily street abuse.Whether you’re learning your first wheelies or smashing combos like a pro, this is a bike designed by riders who live the culture and know exactly what you need.
