The Datum 20 W marks a turning point in road riding; the end of our unhealthy love affair with the 23c tyre…

The Datum 20 W sports the latest Shimano 105 groupset with hydraullic RS405 disc brakes and is all about enjoying yourself, across a variety of terrain, both paved and unpaved, be it fast or leisurely. All the contact points - saddle, bars and crank arms, are womens specific. Not necessarily about out-and-out overall speed, but more fun, adventure, exploration and pneumatically-suspended comfort. More of a large-tyred road disc bike that'll comfortably sit mile-after-mile on tarmac, but, should the tarmac come to an end, it won't mean turning back or the premature end of the ride.
