Modern mountain biking has changed profoundly in recent years.
Bikes are faster, more capable downhill, and allowing an ever-increasing number of riders to tackle terrain that until recently was the preserve of a select few. Added to this is the growth of e-MTBs, which bring with them greater weight, higher average speeds, and significantly greater inertia to manage.
In this scenario, the braking system must also necessarily evolve.
It is precisely from this need that the new 2,2 mm thick Shimano rotors were born, a solution developed to offer greater control, better heat management and superior durability in gravity disciplines, modern enduro and the e-bike sector.
It's not just a question of thickness
At first glance, some might dismiss this innovation as simply a thicker disc. In reality, the issue is much more complex.
When a modern mountain bike tackles long alpine descents, increasingly faster trails or the demanding uses typical of e-MTBs, the braking system is subjected to enormously greater thermal loads than in the past.
A thicker disc means more mass to absorb and dissipate heat, maintaining consistent braking and reducing rider hand fatigue.
For this reason, Shimano has increased the thickness of the new rotors from 1,75 mm to 2,2 mm, accompanying the change with a new design of the ventilation openings.
When Shimano moves, the market listens
The choice takes on an even more important meaning because it comes from Shimano.
The Japanese giant has never been a brand prone to sudden revolutions or passing fads. Historically, every development comes after years of analysis, testing, and field validation.
When Shimano decides to introduce a new technical solution, it often means that that direction represents a concrete market need.
The arrival of 2,2mm rotors can therefore be interpreted as a direct response to the evolution of modern mountain bikes and high-performance e-bikes.
Greater robustness and reliability
In addition to heat management aspects, the new rotors offer greater resistance to deformation.
Those who practice enduro, bike park or downhill He knows well how easy it is to damage a disc during a fall or impact against rocks and obstacles.
The increased thickness helps reduce the risk of bending and improves the overall life of the component.
Available in Center Lock and 6-hole versions
The new range includes:
- RT-CL750 Center Lock
- RT-6B750 6-hole
Both models will be available in 200mm and 220mm diameters.
Shimano has also decided to move from the traditional 203mm diameter to the new 200mm, a choice aimed at simplifying installation and improving compatibility with modern frames and forks.
Compatible with new Shimano gravity systems
The 2,2mm rotors have been developed to work with the latest Shimano four-piston brake systems, including:
- XTR
- Deore xt
- Deore
A solution designed for those seeking maximum performance in downhill, freeride, enduro and e-MTB.
The brake of the future passes through here
In recent years, attention has focused mainly on suspension, geometry and engines.
Today Shimano reminds us that braking must also follow this evolution.
Because as speeds increase and bikes become more and more capable, the real difference isn't just how fast you can go. It's how well you can slow down.
