The Kalloy 820 is an adjustable threadless stem designed to fine-tune handlebar height and reach without changing stem length. It uses a hinged angle mechanism to allow bar position adjustment using standard hex tools.
Constructed from aluminum and finished in black, this stem clamps to a 1 1/8" threadless steerer and accepts 25.4 mm handlebars. The adjustable angle makes it suitable for comfort-focused setups or fit corrections where spacer changes alone are insufficient.
This model is intended for compatibility with common threadless systems and conventional flat or riser bars using a 25.4 mm clamp diameter.
