Pinarello launch Dogma with hydraulic disc brakes

Pinarello have just released the Dogma 65.1 Hydro and DogmaK Hydro for 2014, signalling their intent to join the disc brake movement that is sweeping through the bike industry. Both bikes use SRAM’s Red 22 groupsets and modified forks and chainstays.

We brought you a sneak peek of the Dogma Hydro back in May, when a photo leaked on the Facebook page of US online cycle store Competitive Cyclist of a disc-equipped Dogma. This week the bike is officially unveiled and it’s now listed on Pinarello's website.

Pinarello have opted to use SRAM’s recently released RED 22 Hydro groupset. The Hydraulic Road Disc (HRD) brakes use new levers with the master cylinder hidden internally, accounting for the extra height of the lever. Both bikes are specced with 140mm rotors front and rear, the smallest size SRAM offer. There's also the option of a 160mm up front from SRAM, but Pinarello are clearly happy with the smaller size.

Visually the new Dogma 65.1 Hydro retains the distinctive curves of the regular Dogma that Chris Froome is racing in the Tour de France, but there’s noticeably less waviness to the new Onda HD fork, a result no doubt of the changes necessary for mounting the disc brake caliper. The hose is routed externally along the tail edge of the fork.

There are also new chainstays, with the caliper mounted on top of the chainstays inside the rear triangle. We’ve seen this location used by the few disc-equipped road bikes released so far and we expect it to become fairly standard as other manufacturers jump aboard the disc brake movement.

The rear brake hose has been routed internally, along with the gear cables, producing a very clean looking bike. Rear wheel spacing is 135mm. And unlike the Principia Revolution that we saw recently, Pinarello are sticking with regular quick release axles.

The frame is made from the same 65-ton Torayca 65 high-modulus 1K Nanoalloy carbon, which has a high strength-to-weight ratio, as used on the regular Dogma 65.1. Frame weight for a size 54 is a claimed 950g. This new bike will be offered in 12 sizes.

Pinarello have not stopped at just the one bike, they’ve also released the DogmaK Hydro. This is the bike to choose if you want a more relaxed fit and comfortable ride than the racier Dogma 65.1 offers. It’s the one often chosen by Team Sky for the early season classics, races like Paris-Roubaix, where the longer wheelbase and geometry promote a more stable ride, plus the extra clearance for wider tyres. The DogmaK is available in eight sizes.
