Here are some Frequently Asked Questions about ROTOR 1x13 Groupset Road




Rear Derailleur


Do I need to change some pieces or a specific tool to adjust my ROTOR 1x13 rear derailleur from 12 to 13 speeds?

No – ROTOR has developed The Bolt solution for simple and immediate adjustment to change from 13 speed to 12 speed cassettes. Our tool free gear sync dial allows you to easily turn the dial with your fingers to adjust the synchronisation of the rear derailleur with the cassette.

Is the rear derailleur compatible with the full family of cassettes in the ROTOR 1x13 range?

The rear-derailleur is the intelligent command centre of the ROTOR 1×13 groupset and is engineered so you can choose the gear range you want by simply selection the chainring and cassette size you need. The user profile that aspires to have the best group ROTOR 1×13 may also require different gear ranges for different challenges and our rear-derailleur works perfectly with the cassettes: 10- 36, 10-39, 10-46 and 10-52.

Can I manually select the cassette gear in the case the hydraulic system is damaged?

Yes you can manually select the cassette gear. The rear derailleur has a robust aluminum cover that protects against all external elements, shocks and impacts, so you can get home or to the finish line.

What type of pulley wheels does the 1x13 derailleur use?

The pulley wheels are unique to ROTOR 1×13 group. The tension of the chain in the 13 speed system requires pulley cage wheels that have exceptional resistance so you can access all 13 gears smoothly and designed to operate at the highest level in all types of conditions.

In case the protective casing Armoured Box is damaged, can it be replaced?

Yes. One of the missions of the Armored Box is to protect the derailleur in all situations, from all external elements, shocks and impacts. Although the CNC manufacturing greatly reduces the possibility of structural damage, if necessary it can be replaced so that your ROTOR 1×13 derailleur always looks as good as new.


Do the brake levers of the ROTOR 1x13 group have range adjustment?

Yes. The positions of the brake levers and the shifters are easily adjustable so that all types of cyclists canfind the ideal point of contact for the size of their hand or personal demands.

How often it is advisable to change the oil of the Pulse Hydraulics system?

Pulse Hydraulics uses non-corrosive mineral oil that extends its optimal service life beyond all market competitors.

We recommend an annual maintenance after depending the Kilometers you put in each season. However the standards in this type of system include a maintenance that does not exceed five years.

Can the shift system be put on the left handle?

At the moment it is not possible, but it is a very interesting question that we will address in the future. It’s technically possible but all future modifications to the ROTOR 1×13 groupset adhere to the most demanding validation and test processes.


Is the ROTOR 12s cassette is compatible with Campagnolo groupsets?

No. The ROTOR 1×13 group offers HG free hubs, but the Campagnolo free hub option is not available yet. Our 13s and 12s cassettes are specially designed to work with single chainring systems.

For this reason, although the group ROTOR 1×13 has four versions of 12 speeds, our smallest version, 11-36, would exceed the maximum gear range offered by the Italian manufacturer.

What is the sequence of gear range for each of the four cassettes of the 1x13 groupset?

One of the biggest innovations that we bring to cycling with the launch of the RO-TOR 1×13 group is True Cadence technology.

Gear range and sprocket sequencing developed by analysing pro rider power meter data from over 1 Million KM, 40,380 hours, 2,400 days of competition and 12 million meters climbed. ROTOR 1×13 establishes a new reference in the choice of gear range, offering more range at high and low speed with a better sequencing for every cycling situation.

Can I mount a 10 or 11 speed cassette on ROTOR 1x13 wheels?

No. A HG cassette type of 10-11 speeds does enter the RVOLVER 13s free hub. Our free hub is wider and moved 3 mm inwards to accommodate the extra sprocket. For this reason we decided to create from zero superior hubs, lightweight and high performance, to last a lifetime.

Can I use the hubs in frames and forks with 9mm dropouts (not through axle)?

No, the ROTOR 1×13 RVOLVER disc brake hubs are only available for 12×100 and 12×142 through axle systems as they are the systems that guarantee all the benefits of maximum rigidity and optimum structural efficiency associated with current disc brake systems.

Is there the possibility of mounting an XD type cassette in a RVOLVER hubs?

No, the modular options we offer with the 12s cassettes (11-36, 11-39, 11-46 and 11-52) must be mounted with a Spline free hub HG type like created for ROTOR 1×13 groupset.


What is the size of discs compatible with the brakes?

Our recommendation for Magura road disc brakes is the same as the one suggested by the German manufacturer: 160 mm front and rear.

In this way we can offer a powerful entry in the action of the brake, with good modulation and guarantee a control of the temperature within a stable range even in the most demanding conditions.

Are there only disc brakes for the group ROTOR 1x13?

Yes, for the ROTOR 1×13 groupset there is only the option of disc brakes.

ROTOR is committed to the market trend and benefits offered by disc brake systems.

Hubs and Wheels

Why do not we use Straight Pull radios with ROTOR 1x13 disc hubs?

The disc brake wheels and the rim brake wheels receive completely different forces due to the point where the braking retention is exerted.

In the case of traditional rim braking wheels braking originates on the outside of the wheel. The hub must only withstand the torsional and tractional forces of pedalling and the torsions that are exerted by the weight of the wheel itself.

However, in ROTOR 1×13 groupset disc brake wheels, the retention forces originate in the center of the wheel, from the hubs to the tire, both front and rear.

This circumstance, added to the multi-directional forces that are created by the own pedaling, causes the spokes to turn on themselves with a radiated Straight Pull, with the problem that this entails for the stability in the tension of the spokes.

For this reason, J Bend bend angles are the best choice because they distribute the workload on a larger and stronger surface, which guarantees a more rigid and durable structure over time.

In other words, the RVolver hubs available for rim brakes feature a Straight Pull straight anchor system and the disc brake versions adopt the J Bend layered spoke system.

Can I use the hubs in frames and forks with 9mm dropouts (not through axle)?

No, the ROTOR 1×13 RVOLVER disc brake hubs are only available for 12×100 and 12×142 through axle systems as they are the systems that guarantee all the benefits of maximum rigidity and optimum structural efficiency associated with current disc brake systems.

Are the wheels of the ROTOR 1x13 range are tubeless ready?

In the case of the Carbon 45r version, no. From ROTOR we have not found any full carbon wheel that surpasses our most demanding tests to assemble high pressure road tubeless ready. Our carbon clincher version is designed to offer the best relation between lightness, efficiency and easy maintenance. In this way, we can offer optimized systems in an ideal range of cover size ranging from 23c to 28c.

On the other hand, the aluminum version, designed for a more intense use and perfect for gravel conditions, does allow tubing to obtain a performance perfectly adapted to these conditions of use.


Can I use the same cranks with all chainrings in the 1x13 range?

Yes. One of the main missions of the ROTOR 1×13 group lies in its total versatility. Thanks to the Direct Mount anchoring system, you can choose the chainring you want from 38 up to 54 teeth with increments of 2 teeth.

The Direct Mount system allows you to change the chainring and maintain your cranks with a simple and rigid assembly, reliable and elegant aesthetics.

Chainrings (Q RINGS and Round)

Is there any limitation in the configuration of gear ranges in ROTOR 1x13 groupset?

No, all the configurations that you want with our entire range of cassettes and single-chainring system (Q RINGS® or round) are possible by mounting the same derailleur, without limitations or incompatibilities.

To give an example of unconventional configuration, a 54-tooth chainring can be mounted with the cassette 10-52, or even a chainring of 38t with a cassette 10-36.

From ROTOR we can recommend developments equivalent to the traditional 2×11 combinations, knowing that 1×13 offers a higher range at high speed and low speed thanks to the sequencing of our 13 speed  cassettes.

However, we have a customization table of developments in which we offer all the possibilities so that you can make your own combination and configure your ROTOR 1×13 groupset according to your preferences.

The Q RINGS® have been designed to increase your performance and reduce fatigue of your legs during rides. Our patented ovality of 12.5% ​​is intended to offer a movement more natural than the circumference required by a round chainring, reducing dead spots in your pedal stroke.

If we compare the advance in meters, after a complete cycle of rotation, between a round chainring and Q RINGS®, we will obtain the same result. The benefit is confirmed by having checked biomechanically that, in that same cycle, your legs have worked more effectively with Q RINGS® and, therefore, have suffered less wear and fatigue.

In other words, a round chainring requires constant stress for your legs cycle after cycle, while Q RINGS® offers an alternation in the use of different muscle groups to obtain maximum performance from them without compromising their health and avoiding possible knee injuries.

In addition, with Q RINGS® you can adjust the position of the crank relative to the chainring thanks to the exclusive OCP (Optimum Chainring Position) system, which allows you to adjust the bike to your pedaling style, achieving an appropriate position and angle of action for you.


What chain does the ROTOR 1X13 group use?

In both thirteen and twelve speed formats, 1×13 groupset works with standard 12-speed chains. For this reason we have chosen the market leader KMC X12. It is light, offers extraordinary resistance to stretching, with rapid and precise changes in all types of conditions.

Can I use any 12-speed chain in my ROTOR 1x13 group without needing it to be the KMC X12?

Yes. The KMC X12 chain is our ideal proposal, but you can install the 12 speed chain that you think is most suitable.



With a more aerodynamic 1x chainring set-up how many watts can I gain with 1x13?

A single ring drivetrain gives you internally routed cables with all frames and handlebars on the market for clean aesthetics and to reduce watts in resistance to the wind.

The unobstructed air flow at the central axis of the bicycle provides a more aerodynamic pedalling experience. However, the net gain in optimization of watts for ROTOR 1×13 depends on many factors: such as the length of the cranks, the chainring size and your average cadence.

Are bleeding kits included in the 1x13 Kit options?

No bleeding kits are not included in the four 1×13 kit options. Bleeding kits are sold separately and can be ordered in your local store with a recommended retail price of €115 for the shift system bleeding kit and €39 for the brake system bleeding kit.
