There's not many ongoing discussions as controversial as this one: do you need disc brakes on a roadbike?
Yes or no.
My answer is: it depends.
If you are a long time experienced racer only handling caliper brakes and are fine with the braking power and the brake feeling calipers offer the answer is simple: why change?
If you are a weight weeny: stay with calipers.
If you are looking for the most advanced braking experience with very controllable feedback, very powerful braking, no problems braking in wet conditions: try the disc brake.
If you are coming from MTB racing: go for the disc brake.
Talking about the Oltre XR3 Disc: The Bianchi Oltre XR3 is one of the most superb race oriented disc brake bikes out in the market. It has nothing to do with all the comfort-only oriented, non agile wannabe-racing-bikes out in the market. To describe it in two sentences. The Oltre XR3 is a supersharp but controllable rocket. It's stiff, reactive and agile. PLUS: it offers disc brakes. That's all I need to say. You will experience the fascinating agility & superb braking power on the first ride!
Here are some official specs:
PRECISION AND POWER CONTROL
Disc brakes allow riders to maintain a clean aero form, while achieving a maximum braking efficiency. The key benefit is the modulation of braking power with precision and complete control, in any conditions.
- ALL WEATHER CONDITIONS: Oltre XR3 hydraulic disc brakes are impervious to adverse weather conditions. By developing the new disc brake equipped Oltre XR3, Bianchi allows athletes to ride perfect lines at the optimum speed – for every single corner, rain or shine.
- PERFECT HANDLING: for the rider, the new Bianchi Oltre XR3 Disc is a revelation on the road. Thanks to the Bianchi CV system (with the use of Countervail® carbon material) and the consistent power, precision and modulation of disc brakes, the new Bianchi Oltre XR3 Disc is the ideal handling fast aero road bike - on any road, in any weather.
Oltre XR3 Disc frame and fork are designed to accommodate wider tires. The extra clearance enhances comfort and grip.
In conjunction with its professional testers, Bianchi designed and engineered a new Oltre XR3 carbon frame and fork - as an integrated system – to work specifically with the new disc brakes while maintaining the Oltre’s aerodynamic advantage.
ENGINEERED WITH BIANCHI CV SYSTEM
The Bianchi CV system combines Countervail® patented carbon material with viscoelastic resin. The underlying Countervail® technology used in the XR3 – exclusive to Bianchi CV models – cancels 80% of the vibration resulting in maximized aero advantage and control. Oltre XR3 Disc offers the fastest, most efficient aerodynamic position for longer, with no compromise in power transfer from pedal-stroke to pedal-stroke.
