Review: Lindarets Terske Travel Disc Brake Rotor Lockring Tool


Lindarets Terske Travel Disc Brake Rotor Lockring Tool is a super light and compact solution to Center Lock problems, at least for those times when wearing a steel leg with a regular tool simply won’t work. Your bike will need 12 mm solid axles with a decent wall thickness and rings with external notches to make it work, although – plus its use at conventional torques of 40-50 Nm can be difficult – so it’s a fairly specialized device. But if it suits you, it’s great.

Anyone who has packed a bicycle in a trunk or car is likely to experience the inconvenience when only a few turns of the crank at the other end find that the rotor is bent during transport. Try to suffer noise and thrust and, in addition, try to straighten the rotor with your fingers, as you have almost certainly not packed the rotor adjustment tool.

The answer is to select the rotors and carefully pack them so that they do not hang. However, the tools required are usually large and heavy – with a typical locking ring torque of 40-50 Nm, you need the force to deliver the grains.

The problem is leverage – how do you get the length needed to deliver torque? Not from the coarser multitool, that’s for sure. But now the axles are largely standardized at 12 mm, at least at the rear, you already have about 130-150 mm on your bike.

The American design house Lindarets came up with the idea of ​​using the axle as a lever and this is the result (it also makes a 6/8/16 mm hexagonal tool on pedals and cranks Race Face Cinch).

The tool is machined from 6061-T6 aluminum and then laser etched. It is beautiful and with a weight of 17 g it is also ridiculously light for something that is able to handle a torque of 50 Nm. The secret is how the tool spreads the force from the axle through two wide hollow holes, each of which has a rubber ring inside to prevent the axle from slipping.

The depth of the tool is 4.6 mm, which provides maximum connection to the circlip. Some locking rings may be quite thin, and Lindaret warns to “ensure full engagement and avoid stripping.”

Devil’s torque

40 – 50 Nm is a decent amount to change if you can’t get your whole arm around the handle, and this is an inherent problem when removing or installing the rotor circlip. If you operate a large rotor (160 mm or larger) and use the front axle as a handle, it leaves only 2-3 cm outside the rotor and some of it has an aggressive thread. I have found that it is best to wear gloves to cushion the palm and to protect in case of slipping.

Don’t be tempted to use your foot, stone or any other lever in addition, warns Lindarets – and make sure your axes have a wall 3 mm or thicker (so the center hole is a maximum of 6 mm).

After testing with a torque wrench, I can confirm that 40 Nm is a decent dose to apply this way. With practice, you will appreciate how much is enough – I have secured the rotors years after traveling with other tools and I have not yet experienced any subsequent release.

I have found that in a typical specification of 40 Nm there is a large safety margin and any loosening of the circlip will be apparent due to abrasion / noise of the rotor long before it is dangerously loosened.

Once I completely forgot to add a safety ring in a fit of excitement before a sleepless ride, I only realized this when I got to the end of a long driveway to the camp, when I braked several times. It is not recommended, but it shows that the Center Lock standard can survive torque fluctuations without igniting.

Learn to live with it

I have found that the amount of force you can use here comfortably and safely is more than sufficient. When in doubt, you can always pull the tool out in the middle of the ride to see if anything has changed – if slippage occurs, it can be easily corrected using more force until you decide how much is enough. At home, I made a trial and error until I recognized how much to give, and then I cycled hundreds of miles without any skid.

Please note that these are circlips with an external notch. There are also internal notched locking rings that use a standard Shimano internal groove cartridge locking tool, and it would be nice to see Lindarets offer this option as well. However, if you are interested (and your rotor has a caliper clearance), you can always replace it with external circlips.


There is no such thing on the market. Normal version in full size such as LifeLine Shimano Steps Lockring Tool and a 1/2-inch brake rod will cost you about the same, but will of course have much, much more weight and volume. When it comes to travel, Terske is a class in itself.


If you are swinging outer circlips (best at low torques), massive 12 mm axles and need to remove / refit them wherever you are, this is a sleek, handy and very easy solution.


A unique, lightweight tool that uses your axle as a handle, even though it is far from universal

Tell us what the product is for and who it is for. What do the manufacturers say? How does this compare to your own feelings?

Lindarets says: “Once in a while we find ourselves on the road or away from home and we need a tool that is really very hard to fake. For example, let’s say a 16-notch tool to tighten the external Center Lock and AFS disc brake rotor. And that’s exactly what it is for.

“It works with a 12 mm fixed axle (the rear will give you the greatest leverage effect, but the front will also work) and solves a problem that doesn’t happen often but can ruin your day. Consider it part of your advanced travel tool kit and throw it in “big day” bags, flight suitcase or tool case you have in your suitcase.

“This tool was designed with air travel in mind, when it’s too easy to leave the rotors on wheels and spend your vacation listening to your brakes and generally digging, you’ve skipped the simple step of removing those rotors.”

Tell us more about the technical aspects of the product?

technical specifications

Precisely machined from 6061-T6 aluminum

It weighs only 17 g

For use with 12 mm fixed axes with a minimum wall thickness of 3 mm

Important notes

Maximum torque 50 Nm.

How much does it cost? It’s like hanging 34 lb of things on a handle, 100 mm from the center of the tool (about the middle of your hand at the end of the rear axle). Most rotors specify a torque of 40 Nm (about 27 lb). Even more and you will want a thicker handle.

Hold the tool against the circlip with one hand and tighten or release the handle with the other hand.

Some circlips, especially front wheel circlips, are terribly shallow. Make sure you are fully engaged and avoid undressing.

Use only with 12 mm fixed axes with 3 mm (1/8 inch) or thicker wall (maximum through hole 6 mm).

Common sense is your friend: super-lightweight parts don’t like to be used as handles, but those with a 3 mm wall (common is 3 – 3.5 mm) will give you a good level of safety while maintaining the maximum torque value.

This is a hand tool: Do not use a cheater bar, hammer, foot, stone, or anything else that is not your hand to apply force.

If you overdo it and bend the axle, don’t put it back on the bike! First, it could get stuck. Second, it could be weakened and fail somewhere along the way. You don’t want it, and neither do we.

Wear eye protection. seriously. You only get two and it is very difficult to fix them.

What is the price compared to the price of similar products on the market, including those recently tested on

There is no such thing on the market. A normal full-size locking tool, such as the LifeLine Shimano Steps Lockring Tool and the 1/2-inch grinding bar, will cost you again about the same, which will get you the same price, but with much, much more weight and volume. For travel, it is a class in itself.

Use this field to explain your overall score

This is difficult to score because it is beautifully made with an ingenious design and works quite well … if you have circlips with external notches, reasonably small rotors and 12 mm axles with walls at least 3 mm thick. Ideally, you will also have gloves and you have already loosened the snap ring lower than usual.

If you meet all these requirements, it’s great and reasonably priced, and since there’s really nothing like it, this thing is almost invaluable. In reality, however, it will only work for a relatively small number of riders and even you may have problems. But overall, it’s good.
