Specialized Chisel Expert 1x Mountain Bike 2018
Step into the world of cross-country racing without breaking the bank with the Specialized Chisel Expert 1x Mountain Bike 2018. With a wide range of speed enhancing features, this bike utilises Specialized’s trickle down features from their renowned Epic, but at a price point more affordable for first time racers.
Constructed using Specialized’s D’Aluisio Smartweld M5 Alloy, the overall weight of the bike is impressively low but it’s also incredibly durable, meaning you can head out day after day and keep riding in the knowledge your bikes integrity will never falter. Because of this low weight, you can throw it around the trails easier than ever, and when you point it in the direction you want it to go, it will.
The entire bike is kept in line with the RockShox Reba RL 29 front fork, which offers 100mm of plush, impact absorbing suspension. Softening the blows and enhancing control over rougher terrain, this suspension system offers a 51mm offset to ensure that when you’re facing down steep gradients, you get the stable handling you yearn for. When twinned with Specialized’s tried and tested XC Geometry that’s been tirelessly tested throughout multiple World Cup wins, you get a comfortable and aggressive position for greater performance around the course, too.
SRAM’s Level TL hydraulic disc brakes are a perfect outfit for such a speed orientated bike, giving consistent, reliable and powerful braking in every situation imaginable. Training on damp, wet day around your local loop or heading out onto a dry, dusty course? No problem, this brakeset will see you heading into corners and descending with immense confidence.
Keeping you spinning up hill and reducing fatigue, the SRAM GX 11-speed drivetrain offers a wide range of gearing to see your surging along the flats and overtaking your rivals on the climbs. Equipped with a 10-42t cassette, you get a much deserved and more efficient amount of gears to play with.
Specialized’s own brand Alloy 29 clinchers with Fast Trak tyres connect all of these impressive features to the trail and stay strong, nimble and agile for the duration of your ride. The tyres are designed to reduce rolling resistance whilst offering incredible grip and puncture protection to see you taking faster lines through the bends, and the wheels are lightweight and strong enough for day-in, day-out training and racing.
- 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
- A custom RockShox Reba RL 29 fork offers up 90/100mm of smooth travel (size-specific), while an easily accessible compression and rebound adjusts permit you to customize the feel according to the terrain at hand
- SRAM GX handles one-by shifting duties, practically eliminating dropped chains and reducing overall bike weight
