01. Go Further

Whether you compete with the mountain, the wind or just yourself.
With ROTOR 1×13 you can beat them all.

More range at high speeds, more range at low cadences and perfect sequencing of gears for every situation.

Beauty in simplicity
Forget the headache of front chainring shifting and focus on your natural pedalling rhythm.
One chainring, no front derailleur
Free yourself from the critical moment of front derailleur shifting that breaks your pedalling rhythm and choose from cassettes size combinations to maintain or improve your current effective gear range.
Less parts, less risk
With no need to install and maintain a front derailleur there is less chance of chain loss or mechanical failures when out on the road.
Aerodynamic thinking
A single ring drivetrain gives you internally routed cables for almost all frames and handlebars on the market for clean aesthetics of your bike to reduce watts & resistance to the wind.

Lightweight
With less components on board, ROTOR 1x13 gives you a super light ride for the steepest of challenges.
Lightweight & robust
With cutting edge CNC manufacturing, 1x13 strikes the perfect balance between lightness, precision and reliability. Only 1,785 g including Rear Derailleur, Shifters, Brakes (Flatmount Calipers and 160 mm rotors) and hydraulic hardware (uncut hoses), 10-36 13s Cassette, Chain (uncut 126L)
Disc brake designed
Design thinking focused on delivering lightweight high-performance braking that is lighter than most existing rim brake groupsets.
Lightness where you need it
With shift indexing in the rear derailleur the distribution of component weight adds to the natural balance and stability you demand from your ride.

Data driven gear range and sequencing
True Cadence technology with a wide selection of gearing choices to match your cycling needs.
2x11 = 14
Due to overlap of combinations the traditional 2x11 set-up means you really only have 14 effective gears. ROTOR 1x13 is a real alternative with options for wider range and better sequenced gear steps.
Increased range and optimised sequencing
More evenly spaced gears for the toughest climbs with more range to push harder on the flat or fast descents. - True Cadence is our technology.
Precision
Our innovate Flow Ramp cassette teeth profiling keeps you in control of your shifting at the speed and pace you want.

Reliability
Proven hydraulic technology for cycling all terrains so your ride doesn’t finish where the tarmac ends.
Minimize your risk
1x13 Pulse hydraulics closed system is totally sealed so water, mud, dust, low batteries or interference will not affect your ride.
No chain failure
Avoid chain failure in moments of maximum intensity as no front chainring shifting required.
Precision
Our innovate Flow Ramp cassette teeth profiling keeps you in control of your shifting at the speed and pace you want.
No batteries, No maintenance
No more changing cables, covers or recharging batteries. Whether you rip through the mud or pedal thousands of kilometres - ROTOR 1x13 looks after you and itself.

02. Go Wherever

Pushing yourself to improve is all about finding the rhythm of your optimal cadence to go further, faster and stronger.

ROTOR 1×13 has revolutionised the drive train transmission with a gear range that offers a real alternative to the traditional 2×11 configuration.

Did you know 2x11=14?

Although the traditional 2×11 groupset has 22 theoretical gears, the effective gear range is 14s due to overlap of chainring and sprocket combinations. To access these 14 gears in the correct order, multiple front derailleur shifts are required.

ROTOR 1×13 has 13 effective gears that you can shift sequentially up or down without the risk of front chainring mis-shifting. 1×13 is a lightweight, aerodynamic and reliable system that offers you freedom to adapt your pedalling as the slope of the road dictates.

Customise your 1x13 groupset

Identify your current metered gear range in the upper table to find the equivalent combination with 1×13 choices in lower table.

Now you can choose your combination according to your preferences to climb higher, ride faster or sprint stronger.

The ROTOR 1×13 groupset allows you to increase your gear range and improve your performance with less components and more reliability.

For example:

If your current gear range is 53/39 & 11-28, it means your progress (m) is: 10,17 – … – 2,94.

If you want an equivalent 1×13 gear range, you can choose 50 & 10-36 and you will get more range in both extremes (progress: 10,56 – … – 2,93).

However, if you want to climb higher and more comfortable, your options could be 48 & 10-36 or 48 & 10-39.

With ROTOR 1×13, you manage your ride.

03. Go Deep
