The Pleg 2+ features a completely re-designed 7075 aluminum core and proprietary plastic sleeve. This new design allows for a smaller overall peg diameter and substantially increases stiffness. The Pleg 2+ core runs 3/4\" of the length of the sleeve so direct damage to the core\'s end can be avoided, simplifying sleeve removal and maintaining socket fit. ###section### Product Specs LENGTH: 4.25\" (108mm) DIAMETER: 39mm MATERIAL: Plastic AXLE SIZE: 10mm / 14mm PACK SIZE: Single WEIGHT: 105g / 3.7oz
