Genesis Datum 20 2018 Womens Bike
Genesis is a UK bike brand specialising in no-nonsense road, touring, urban and mountain bikes for adults and children. Ranging from great value models upto competition-ready racers and with the dire UK weather in mind, they are generally suited to mixed weather conditions and offer comfortable geometries.
The Datum is part of Genesis' Adventure range, offering a smooth, relaxed and highly efficient ride on or off-road, with the benefit of robust assets such as high volume tyres, stiff 15mm thru-axles and hydraulic disc brakes to get you through the less-savoury sections of the Great British countryside.
The women's Datum 20 uses the same spec. as the unisex version but uses a slightly shorter stem, crank arm and toptube relative to frame size, in order to accommodate female proportions which generally mean a slightly longer leg to torso/arm ratio and narrower shoulder.
With a 24/30T Modulus Carbon frameset used throughout the range, the Datum is super light and highly compliant on both straights and sharp corners, with a forgiving level of vibration absorption. The Datum 20 is the intermediate model in the range, offering a Shimano 105 2x11-speed mechanical drivetrain and matching spec. hydraulic disc brakes for all-round crisp and unwavering performance. Rolling on some capable Formula hubs with Jalco Alloy rims, and finished up with an Alloy cockpit and seatpost to keep the overall weight low and to also keep the pricetag as reasonable as possible (also leaving room for future upgrades)
The Datum has 3 other models for 2018 as well as the women's geometry mid-range model to accommodate riders with varying levels of enthusiasm and allowance.
