Bombshell Ratchet 2024 cranks are fully CNC'd crank set. Lighter and stiffer cranks are more efficient and making our own cranks and spiders allows us to create perfect fit for every frame. Bombshell Cranks have been an industry leader for over 12 years. Adding half sizes reflects industry demand for every single detail turning it into advantage on the track. Decreased Q factor by 10 mm still provides sufficient clearance on all BMX frames. Interchangeable spiders allowing to install chairing inside/outside to finetune chain line on every single hub/ frame/ crank combination. We always deliver unique Bombshell design. We listen to riders needs and comments, trying to make better and better products. Ratchet cranks are fully redesigned and improved to deliver better ride overall. Fatigue testing of AL 7075 - Hollow 24 MM spindle for super light weight, and new spider design for better chain alignment, overall contact area between spindle, and arm adding required stiffness to transfer the power to the rear wheel. Feel the difference. Ride the Ratchet.
