Pinarello unveils Dogma F8 Disc

Dogma F8 gets the disc brake treatment

Italian bicycle manufacturer Pinarello has unveiled the new Dogma F8 Disc. Pinarello is no stranger to disc-equipped road bikes, it first launched the Dogma 65.1 Hydro and DogmaK Hydro disc road bikes two years ago, road.cc even had a ride on one.

The new Dogma F8 Disc though is based on the same Dogma F8 that Team Sky has been racing for the past two years, since its launch last summer, Pinarello’s first aerodynamic road bike. The new Dogma F8 Disc is said to retain the “main characteristics” of the regular Dogma F8, in terms of the geometry, the frame material, stiffness and aerodynamics.

The frame uses Shimano’s new Flat Mount brake caliper system, with adapters to make it compatible with other brake systems. Pinarello hasn’t issued many details about its new bike in its press release, but we’re pushing them for more details. We expect the frame to carry a slight weight penalty over the regular Dogma F8, but how much we don’t know.

Pinarello also appears to have stuck with conventional quick release axles rather than adopting the thru-axles that a handful of other bike brands have done. 

- Disc brakes to appear in pro peloton this year

The UCI recently relaxed its rules on disc road bikes in the professional peloton so it’s no surprise we’re starting to see race-ready road bikes equipped with disc brakes starting to appear. Most disc-equipped road bikes so far have been based on endurance/sportive bikes, as the brakes suit the intended use of those bikes, and the longer chainstays get around chainline issues with the wider rear axle. Will Team Sky be one of the early adopters?

More on this new bike soon... www.pinarello.com

modulation imo is more of a personal thing, rather than the braking systems'. And ime, rim brakes are more easy to handle under hard braking, as the braking fore is focused on the centre - disc brakes tend to veer off to the left/right depending on which side the brakes on.

What? Disc brakes do not pull to one side.

1. The disc brake on a bike applies the braking force to the disc, which is attached to the hub, which pulls on the spokes, on both sides, and then this force is moved outwards to a single contact patch on the tyre.
2. For there to be a pull left or right you need two wheels side by side, and then the braking force on one of the wheels to be more/less than the other. This can happen with any type of brake, but it MUST have the two wheels side by side.

define modulation ?

I'm really struggling to see the need for disc brakes in high level road racing.

Sure, its great to have options as a consumer, so if it drives innovation then that's a good thing. But braking efficiency isn't currently limited by rim brakes, its limited by the size of the contact patch of the tyres on the road. Discs brakes won't mean that the riders will stop faster on 23mm tyres, it will just mean that the riders have to be more careful not to skid.

Add to this that the discs will undo some of the aero "marginal gains" that the teams work so hard for, and I just don't see why the riders would want to use them.

Wrong.

It's not about out and out power in terms of ability to lock wheels. The power and better feel that disc brakes have allows finer adjustment (partly due to only needing one finger to use) and therefore greater modulation, meaning that you can get closer to the point of locking up without actually locking.

I've seen it quoted somewhere that with rims brakes people tend to only use up to 70% of the power, because the relative lack of modulation means it's too easy to lock up beyond that point, where-as discs allow you to get to 85-90% of the power before your confidence and or skill level prevents you from trying to get any more out of them.

Just look at all the reviews of shimano hydraulic discs - they all say that the brakes allow you to brake harder and later and with more control.

Also, when will everyone realise its not just about the brakes, but what disc brakes will allow innovation wise elsewhere on the bike, the main one being rim development given that a brake track will no longer be needed.
