The TR stem is a little bit lighter and more suited to trail and all mountain use compared to the style of the Gravity stem. Optimum machining has been used to obtain the lightest weight without compromising stiffness. Opposing steerer clamp bolts provide exceptionally rigid steering characteristics while the 2-piece front plate design with a simple "no gap" clamping system.CNC machined from a solid billet of 2014 T6 aluminium with optimum machining to reduce weight without compromising stiffnessStainless steel taper head screws supplied56 mm clamping width for reliable strengthZero rise TECH SPECS table{border-collapse:collapse;width:auto;max-width:100%;} td{text-align:left;padding:12px;font-weight:350;word-wrap:break-word;} tr:nth-child(even){background-color:#f2f2f2} th{background-color:#eb212e;color:white;text-align:left;padding:8px;} .desc .specs-heading{font-size:24px;font-weight:600;padding-top:35px;border-top:3px solid #f0f0f0;display:inline-block;border-bottom:4px solid #eb212e;width:142px;margin:0;} Stem Angle (deg) 0 Length 32 Material Aluminum S.H.I.S.
