Genesis Core 20 2014 Mountain Bike. The wheel size may have changed but we've not strayed from the proven Core formula of dialled trail geometry partnered with durable, quality kit that can happily handle the kind of riding the bikes' geometry inevitably inspires. 27.5'', 650b, SixFiftyB, call it what you will but it seems the 'in-betweener' wheel size is here to stay and brings with it some very tangible benefits to the table too. Sitting as a nice halfway house between the wagon-wheeled 29ers and the longstanding 26'' wheel, the 27.5'' wheel not only rolls better than its smaller 26'' counterparts but is also both lighter and more manoeuvrable on technical terrain than a 29'' wheel. Win-win in Genesis's book and ideally suited for their Core models. The Core 20 represents the ideal bike to accompany you into the muddy and adrenaline-fuelled world of mountain biking, with a lightweight, yet rugged 6061 Double-Butted aluminium frameset, wide-range 9sp drivetrain, powerful Shimano hydraulic disc brakes and a tuneable 120mm RockShox air-sprung fork (with lock-out for efficient climbing) ensuring nothing is left wanting on the technical front. A fun, great handling trail bike that benefits from the smoother-rolling, increased traction benefits of the bigger 27.5'' wheels.
6061 Double-Butted Aluminium: The butting process meanwhile ensures ample wall thickness and strength where required but trims any excess and extra unnecessary weight where it's not. 27.5'' Wheels: Sitting at a nice halfway house between the wagon-wheeled 29ers and the longstanding 26'' wheel, the 27.5''wheel not only rolls better than its smaller 26'' counterparts but is also both lighter and more manoeuvrable on technical terrain than a 29'' wheel. Win-win in our book. Size-Specific Handlebars: Going that extra mile with the attention to detail to ensure a better fit - the 14''-16'' are specced with 680mm wide handlebars whilst the 17.5''-20.5'' come with a wider 700mm handlebar. Air-Sprung Fork: The air-spring allows precision tuning for rider weight and trail conditions for unsurpassed performance.
