CNC-machined from 6061-T6 aluminum and equipped with six titanium bolts, this stem delivers increased stiffness and reduced weight compared to traditional 22.2mm BMX stems. The oversized 31.8mm bar clamp area provides a more rigid connection between bars and fork, improving front-end responsiveness for racing applications.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e31.8mm Oversized Bar Clamp\u003c\/strong\u003e – Larger clamp diameter creates a stiffer interface between handlebars and stem, reducing flex during hard accelerations, jumps, and aggressive cornering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6061-T6 CNC-Machined Aluminum\u003c\/strong\u003e – High-strength alloy construction with precision machining ensures strength while minimizing material and weight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix Titanium Tapered-Head Bolts\u003c\/strong\u003e – Titanium hardware (M8 x 25 x 1.25) significantly reduces weight compared to steel bolts without sacrificing clamping strength\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e33mm Low Stack Height\u003c\/strong\u003e – Shorter steerer tube stack allows for lower bar positioning and reduces overall cockpit height\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e29.93mm Stem Rise\u003c\/strong\u003e – Distance from bar center to stem bottom provides consistent geometry across all reach lengths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBar Clamp Diameter: 31.8mm (oversized—requires 31.8mm handlebars)\u003c\/li\u003e\n\u003cli\u003eSteerer Tube Diameter: 1-1\/8\" only\u003c\/li\u003e\n\u003cli\u003eMaterial: 6061-T6 aluminum alloy\u003c\/li\u003e\n\u003cli\u003eClamping Type: Top load\u003c\/li\u003e\n\u003cli\u003eBolt Material: Titanium (6 bolts, M8 x 25 x 1.25 thread)\u003c\/li\u003e\n\u003cli\u003eStack Height: 33mm\u003c\/li\u003e\n\u003cli\u003eStem Rise: 29.93mm\u003c\/li\u003e\n\u003cli\u003eAvailable Lengths: 45mm, 50mm, 53mm, 57mm, 60mm\u003c\/li\u003e\n\u003cli\u003eColor Options: Anodized Black, Polish, Red, Blue\u003c\/li\u003e\n\u003cli\u003eWeight: 45mm (229g \/ 8.1oz) | 50mm (249g \/ 8.7oz) | 53mm (259g \/ 9.1oz) | 57mm (269g \/ 9.4oz) | 60mm (277g \/ 9.7oz)\u003c\/li\u003e\n\u003cli\u003eMaximum Torque: 13Nm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility and Ideal Use Cases\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility Requirements:\u003c\/strong\u003e This stem requires 31.8mm oversized handlebars and a 1-1\/8\" steerer tube fork.
