Introducing the Datum; our second carbon-framed model, following hot on the heels of the Zero with the traditional Genesis unconventional twist.
It’s our new large-tyred road disc bike that’ll comfortably sit mile-after-mile on tarmac, but, should the tarmac come to an end, won’t mean turning back or the premature end of the ride. Not necessarily about out-and-out overall speed, but more fun, adventure, exploration and pneumatically-suspended comfort.
Keen not to pigeonhole such a versatile bike, the Datum is really just a bike for riding around and enjoying yourself, across a variety of terrain, both paved and unpaved, albeit fast or somewhat more leisurely. It could be a gravel bike to some, in the same way it could be a fast, comfy road bike to others…
BB86 Press-Fit Bottom Bracket provides the basis for a stiffer, more efficient pedalling platform and wider spaced bearings which helps spreads the load increasing longevity to help you keep spinning smoothly mile after mile.
TRP's revolutionary Hy/Rd-C brakes combine traditional cable actuation with hydraulic power to great effect, allowing you to enjoy all the benefits associated with hydraulic braking (good power and modulation, self centring pads, minimal maintenance) without the expensive dedicated hydraulic shifter setup. We've also combined them with Jagwire KEB-SL compressionless outer for optimum performance. The devil's in the detail!
Brand new, larger 700x33c Challenge Strada Bianca clinchers use the same proven tread as found on their Paris-Roubaix model on a larger volume 33c casing. Competeively light @ 355g considering there's a PPS (puncture protection strip) underneath the tread too!
Naturally there are mudguard eyelets – x2 on the inside of either fork leg just above the caliper which are still low enough to provide a stiff, supportive mount but unobtrusive if not in use, and threaded eyelets on the back of fork crown, backside of the bb shell and underside of the seatstay bridge (it’s only there to provide a mounting point for a mudguard). 32/33mm tyres and 45mm full-length guards should fit fine.
