Description

Promax Impact stems have a 45-degree top-load clamp design for BMX racing and freestyle. This oversized 31.8mm clamp version is available in 53mm and 60mm lengths. Cold forged from the highest quality 6061-T6 aluminium then CNC machined to refine the shape and further reduce weight.

The "open" design keeps weight low (265 grams in a 53-mm extension), while maintaining plenty of strength and ensuring your bars stay put. These Promax stems are our pick for one of the best value for money stems on the race market.
