Promax Banger stems have a front-load design and can be used with either side up, providing a 5-millimeter drop or rise. Available with 48-millimeter and 53-millimeter extensions, they are cold forged from the highest quality 6061-T6 aluminum then CNC machined to enhance the shape and further reduce weight.
