Bombshell Ratchet 2-Piece BMX Crankset 180mm Black 7075 aluminum 24 mm shaft

  

Bombshell Ratchet 2019 is next generation of our US made, 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.

It has been over 7 years now when our new 2 pc cranks started taking titles all over the World. Ratchets come in more sizes than before. 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 clearence on all bmx frames.

Interchangeable spiders allowing to install chairing inside/outside to finetune chainline on every single hub/ frame/ crank combination. We always try to deliver unique Bombshell design, 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 - T6 spindle exceed strength of comparable crmo product while responding better to force applied to crank arms. New spider locking system increases overall contact area between spindle and arm adding requiered stiffnes to transfer the power to the rear wheel. The fact we machine cranks in house gave us a chance to increase strength, adding more material where needed while keeping the weight down to a minimum. Mini 135-155 mm rider weight limit 85 lb. Expert 160-170 mm rider weight limit 150 lb.

Pro 175-180 mm rider weight limit 250 lb.
