Stems

A vibrant and affordable A-head stem that’ll turn heads. The 6 degree drops means you can set it to be flat or have it rise up a bit for that more alert position when riding in heavy traffic.

The stem has a trapezoid shape with a flattened top section for torsional stiffness and excellent aerodynamic performance.

Designed for the most demanding riders, the stem is manufactured using an innovative 3D alloy forging process.

The BLB Lite CNC stem offers the best combination of lightweight, strength and stiffness making this a solid choice for any cockpit and those looking for performance.

The one-bolt clamping mechanism makes this stem lighter and slick looking. Capable of running flip-flop you get a 7º rise/drop depending what way up you run the stem and a 41mm stack height.

The 6066 T6 aluminium alloy with which this stem is manufactured is processed with sophisticated CNC machining steps, both internal and external, in order to obtain variable thicknesses.

The result is a stem that expresses strength and high technology. The front panel has the lightning bolt of Mash cut into it and the machining on the sides of the stem’s body are emphasized by the two logos.

Quill (22.2 mm) stem for one inch threaded head set, open clamp for 26.0mm handlebar diameter. Drop forged and CNC turned 6061 T6 aluminium light alloy.

F5 always wanted a stem that could accommodate 31.8mm handlebars without having to use an adapter and still look classic enough that it would compliment any 1″ threaded headset bike.

Made from 7075 aluminium, it is incredibly light. The removable faceplate is held in place with two stainless steel screws and subtly finished with the Circle F5 logo laser-etched in the centre.

The stem is high polished and deep anodised in silver and black to give the traditional quill stem look. It delivers performance and style, which for a component with so much attention, delivers exactly the right level of satisfaction.

The fully rounded design adds strength and allows the stem to be milled out to an insane degree.

This stem was designed from the ground up to be stiff, strong and pretty darn light too. The rounded box shape is some 25% stiffer than the competition and after extensive real world and machine testing, proven this to be the best combination of these three principles as well as one damn strong stem!

The stems come in a zero rise and a +/- 15 degree rise. Lengths are 50, 70 and 90mm. All screws are the same pan head T25 Torx type screws in stainless steel. Why Torx? Because they work so well, and are the same wrench size as the ubiquitous rotor screws all makers use. All screws are high strength stainless steel with the popular T25 head. Made in Chico, California with US sourced 2024 aircraft alloy.
