Product Information

Specialized Chisel Expert Men's Mountain Bike

It's been said, "If you haven't ridden an aluminium bike lately, you haven't ridden an aluminium bike." The Chisel justifies this quote not only for the premium aluminium the frame was constructed with but the D'Aluisio Smartweld technology that went into the welding of the frame allowing greater compliance, whilst remaining lightweight and stiff. The Chisel Expert comes kitted out with SRAM NX Eagle 12x1 11-50T groupset allowing enough gears to spin up your favourite MTB tracks as well as grind down your favourite trails. To finish with, last years XC geometry has now been revised with trail aspects that provides greater stability down the hills and round the bends. 

Full Specification



Strong, Stable & Lightweight M5 Aluminium

Given its lightweight and ultra-stiff characteristics, M5 aluminium was the natural choice for the frame's construction. And when complemented with Specialized's speed-focused XC 29 Geometry, D'Aluisio Smartweld technology, and internal cable routing, you get a bike that compromises nothing in delivering explosive speed, confident handling, and hassle-free maintenance.


Smooth Travel on Every Trail

A custom RockShox Reba RL 29 fork offers up 90/100mm of smooth travel (size-specific), while an easily accessible compression and rebound adjust permit you to customize the feel according to the terrain at hand.


SRAM 12-Speed Groupset

SRAM's 12-speed NX Eagle groupset, with its 11-50t cassette, provides a wide gear range that lets you spin up the climbs, yet have plenty of top end for the descents. One-by setups also decrease weight and make it next to impossible to drop a chain.

Great quality aluminium is a world apart from mass-produced, poorly constructed carbon. The Chisel Expert has been designed to provide compliance that you would expect from bikes far further up the market and looks like great hardtail fun for any track or trail. 8/10
