Genesis Core 20 Hardtail MTB Bike 2016

Product Code: 145570

Pound-for-pound, the Core 20 is arguably one of the best equipped bikes available in our range.

On shifting duties is Shimano's brand new Acera groupset, getting some much appreciated trickledown tech and features from Shimano's higher tier mtb groupsets.

We've plumped here for close ratio 40/30/22T gearing, which, when combined with the 11-34T cassette out back gives an optimal spread of gears for the larger 27.5" wheels.

Keeping you suspended is Suntour's air-spring XCR fork, offering 120mm of plush travel that's 100% adjustable for rider weight and preferred riding style for stable, confidence-inspiring surefooted control.


Hybrid 6066/6061-T6 tubeset

At the heart of the Core lies our brand new hybrid double-butted alloy tubeset – a clever mix of two differing grade alloys to help give us high levels of stiffness in certain areas and compliance/flex in others. The higher density 6066 downtube and chainstays provides the basis for a stiff and efficient pedaling platform, whilst the 6061 toptube, seat tube and seatstays help give and added element of compliance and comfort, acting as a nice buffer between rider and trail.

Tubeless-ready rims

Nice and wide Alex MD23 rims (28.4 mm OD/23mm ID) give a great high volume, tyre profile and have a tubeless ready bead hook – just add rim tape and sealant.

Air-sprung fork

The air-sprung Suntour XCR 120mm fork (with Hydraulic Speed Lock-out & Rebound adjust) is not only lighter than traditional coil-sprung model, it also allows the rider to easily tune the fork to to his/her weight, preferred riding style and trail conditions via an easily accessible value on the fork crown (a specific high-pressure/low volume suspension pump will be required).

27.5" Wheels

Sitting at a nice halfway house between the wagon-wheeled 29ers and the longstanding 26in wheel, the 27.5" wheel not only rolls better than its smaller 26in counterparts but is also both lighter and more maneuverable on technical terrain than a 29" wheel. Perfect middlegorund/best-of-both - Win-win in our book.
