  • Why are your Ab chainrings better than the others?

    We have spent years of scientific research using the most advanced tools one can make to perfect the product. We own the only scientific-grade 3D force measurement system in the world capable of measuring the forces on the pedal in any direction with great accuracy, as well as hip-knee-ankle angles, efficiency, mechanical effectiveness and so on. With such a device, we are able to measure all the changes that occur when using different chainrings and the differences between riders. Without such a device, it is impossible to really optimise the chainring. We are the ONLY company that has such a device and a scientific lab dedicated to pedal optimisation. Other companies throw darts in the dark, so to speak.

  • What is the difference between WolfTooth, Oneup and Absoluteblack Oval chainrings?

    Absolute Black invested more than 3 years in research before coming out with the first oval chainring. Other brands started producing their sprockets after only a few months. However, all the patents held by Absolute Black prevent other brands from meeting the same quality standards as Absolute Black.

    At Absoluteblack, we believe we have created the perfect shape of an oval chainring to support our claims.

  • Do I need a different chain for an oval chainring?

    All chains on the market except "half link" chains work perfectly with an oval chainring. That is, all 6, 8, 9, 10, 11 and 12 speed chains are perfect for it. For singlespeed, we recommend using an 8spd chain for more durability.

  • Which gearing should I choose for my oval sprocket?

    We always recommend using the same gearing as for a round sprocket.

  • I have a Boost148 rear, will the direct mount Sram / RF Cinch ovals work correctly on my bike?

    Yes, definitely and definitely. We have a special version of Sram and RF direct mount rings with the correct 3mm offset for Boost frames. So when purchasing, choose the chainring option "Boost 148".

  • What are the dimensions of the bolts?

    Long bolts: M8x0.75, 8.5mm long thread and 7mm high nut. Short bolts: M8x0.75, 6.5mm long thread and 4mm high nut.

  • Why is an oval chainring more effective than a round chainring?

    The human body uses skeletal muscles to generate force on the pedals, mainly during the downstroke. Each skeletal muscle has a unique characteristic that makes even muscle force throughout the contraction impossible. For example, the peak force of the knee occurs at a crank angle of about 70 degrees (0 is at 12 o'clock), while the hip peaks well past the crank angle of 90 degrees. If we add ankle joint force, crank angular velocity, leg inertia and force effectiveness, i.e. how much of the force generated by the muscles is actually converted into power, we see that a force profile during a crank cycle is not uniform, but peaks somewhere around 110 degrees of the crank cycle (normal road cycling for example). AbsoluteBLACK oval chainrings are designed to perfectly suit a specific riding style and involve the hip joint to a greater extent, essentially relieving the knee and contributing to muscle efficiency. The orientation of the major axis of AbsoluteBLACK oval chainrings, i.e. when the diameter of the chainring is largest, corresponds to a cyclist's power profile to reduce power loss and shift the load from the knee to the hip. This was established based on several thousand measurements using a unique diagnostic equipment to measure 3D pedalling forces and joint loads. Measurements were made on thousands of recreational road and MTB riders and hundreds of professional riders, including the entire Pro Tour Team UAE, where we officially provide our scientific biomechanical optimisation services with our Science Lab. With such a wealth of data, we are able to accurately design chainrings that can increase mechanical effectiveness - meaning you experience it as less effort at the same speed compared to around.

  • Will my chain wear faster or slower with an oval chainring?

    Our oval chainrings are designed to always pull the same amount of chain in any position of crank rotation. Imagine an ellipse that you can cut through the middle at any position and equal halves will always come out. The same applies to the circle. This causes the chain to wear in the same way as with the round chainring. Obviously, the best way to extend the life of a chain-chain combination is to lubricate the chain regularly and keep it clean.

  • Which bolts do I best use to mount my sprocket?

    For round gears: Bolt 4S/Bolt5S. Bolt4S = 4 bolts, Bolt 5S = 5 bolts.

    For oval sprockets: Bolt 4L/Bolt5L. Bolt 4L = 4 bolts, Bolt 5L = 5 bolts.

  • Are the right bolts included in the package?

    Bolts are never supplied as standard unless otherwise stated. In doubt?If so, please contact us.

  • What is the difference between bolt covers (Dacover) and bolts (Bolt)

    Unlike the bolts, the covers provide a premium finish where everything from bolt is elegantly concealed.

  • How do I put on my overshoes correctly?

    To put on your overshoes correctly, please watch the following instruction video: https://youtu.be/R4iOizOmHgA

  • How do I clean my Spatz overshoes?

    The best way to clean your boot overshoes is to rinse them first with cold or lukewarm water. Use mild soap and a soft sponge to wipe off stubborn dirt. Of course, you can also just take your overshoes into the shower. Then they will definitely be clean for your next bike ride.

  • How do I dry my overshoes?

    Dab off excess water with a soft towel. Use the Velcro fasteners to hang up the overshoes in a warm place.

  • How do I store my overshoes?

    The most important message we can give you is that neoprene can crease when you fold your overshoes. This will not affect your performance but it is best to avoid it.

    To store them, it is best to put them on a shelf or in a cupboard without folding them. Of course, you can also just leave them hanging on your clothes rack after drying.

  • Will Spatzwear make me sweat like crazy?

    SPATZ are designed for cold and/or wet conditions. If you sweat a little in SPATZ, we've done our job. SPATZ's lining is designed to actively wick away moisture, but most importantly it keeps the trapped moisture WARM. Think of a "wetsuit". Experiment with wearing SPATZ under and over your leg warmers/tights and find out what works best for you in what conditions.


  • What makes Solestar insoles so unique?

    SOLESTAR insoles offer an unprecedented level of construction and materials. Our patented Stabilisation-Delta technology makes all the difference, putting your feet in the optimal position for maximum stability, comfort and performance in all types of sports.

    SOLESTAR insoles have a special, patented structure that guides the foot into the neutral position and stabilises it in this position. In addition, SOLESTAR insoles have a load-bearing core. From the forefoot to the hindfoot, this core supports the foot and ensures that the foot does not lose its stability and that power is transferred optimally.

  • How can I be sure the Solestar sole will fit my shoe?

    Every shoe brand uses different sizes. Therefore, you may have to take size bigger or smaller compared to the size of your cycling shoe. Check which insole size fits your shoe via this link.

  • Are SOLESTAR insoles really only something for professional athletes?

    SOLESTAR insoles are co-developed by professional athletes, as this is where optimisation opportunities are constantly sought. The pros are therefore usually the first to learn about such innovations. Nevertheless, SOLESTAR insoles are for every athlete who wants to perform their activity with more comfort, control and better power transmission. In addition, SOLESTAR insoles prevent the typical overuse complaints associated with sports.

  • What is the difference between Solestar insoles and other brands?

    Other insoles usually do not have a solid core. Therefore, these insoles deform as soon as they are loaded. In certain sports, such as cycling, running, cross-country skiing and hiking, the foot needs to be stabilised, which is only possible with materials that are stable under load.

  • How long does it take to get used to the SOLESTAR insole?

    The SOLESTAR insole for brings the foot into the optimum neutral position. The foot and the body structures involved, such as muscles, tendons and ligaments, usually need some time to adjust. It may take four to five training sessions for your body to fully adapt to the change.

  • How long can I use a SOLESTAR insole?

    The service life depends on the pattern of use. An indication of wear is a decrease in original stiffness. Your dealer can tell you exactly whether your current SOLESTAR insole is still usable. In most cases, the useful life of SOLESTAR insoles depends on how long you use your sports shoe.

  • Do I need to remove the original insole from the shoe when using SOLESTAR insoles?

    Yes, this is absolutely necessary. The SOLESTAR insole replaces the original insole. If the original insole remains in the shoe, the SOLESTAR insole will not fit or work.

  • What if the soles don't bring what I expected after all?

    We want you to be 100% satisfied with your SOLESTAR insoles. SOLESTAR performance insoles have a direct effect on your muscles and movement patterns in cycling, running and skiing. It may therefore take up to 5 sessions until your body has adapted to the change. 

    If you are not happy with your insoles after having used the insoles for this number of rides you may return your insoles at a full refund within the first 6 weeks after your purchase.

    Please note that a refund is only possible under the following conditions:

    • Insoles solely ordered for size comparison are sent back unused;
    • The soles may be used but not modified (e.g. shortened or similar, except Neutral Run/Hike/Kick);
    • An identical product may only be ordered and returned once by each customer.


  • How much pressure do I pump into the booster?

    The pressure in the booster depends very much on the rim combination and whether the tyre is already inflated. At 6 bar / 87 psi, in most cases only good rim combinations or tyres that are already inflated will work. At 8 bar / 116 psi, most tyres work and only in a few extreme cases the full 11 bar / 160 psi is needed.

  • What size of Booster do I need?

    One of the main advantages of the milKit tubeless booster is its highly efficient air flow: unlike other tubeless boosters, the milKit booster has no hose and therefore no pressure loss - the full air pressure is right at your valve. With so much air shooting into the tyre in an instant, even the small booster is efficient enough to inflate any tyre (except fat bike tyres). So the choice of booster depends on the size of your bottle: perhaps a compact 0.6L / 17oz or 0.75L / 25oz to fit in your bottle cage or the large 1.0L / 34 oz to carry more water on your ride.

  • Can I use the booster with any valve?

    The milKit tubeless booster can be used with any Presta tubeless valve. The milKit valves have the advantage (besides the ability to measure and refill your sealant without letting the air out of your tyre) of keeping the air in the tyre without the valve core in the valve - making inflation easier and more efficient.

    Presta valves with external threads that do not extend to the top of the valve reduce the efficiency of the milKit booster.

  • Does the booster fully seat my tyre on the rim?

    The booster is only meant to pre-pump your tyre so that it sits tight enough on the rim to keep the air in. You then have enough time to apply sealant through the milKit valve, use the milKit syringe and needle to screw back the valve body and pressurise the tyre to full pressure until it pops fully onto the rim.

    If your tyre does not hold the air well after pre-pumping with the booster, you may need to first screw back the valve, bring the tyre to full pressure until it pops fully on the rim, and then reduce the tyre pressure to less than 1.5 bar / 22 psi to apply the sealant into the tyre.

  • Can I use Milkit with other brand valves?

    Our valves are custom-made as they have closed rubber flaps at the bottom.
    This has several advantages:

    • The valves no longer clog up.
    • They keep the air in the tyre even if you remove the valve (easier fitting of tubeless tyres).
    • They allow measuring and topping up sealant with the air pressure still in the tyre.

    You can use valves from other brands, but then you will not benefit from the best advantages offered by MilKit.

  • How much sealant should I put in my tyre?

    Many factors can influence the decision on how much sealant to put in a tubeless tyre. Some tyres "absorb" a lot of sealant, and a few days after fitting, a significant amount of the sealant is gone. This is where the milKit valve and spray system comes in handy: we recommend always checking how much sealant is left in the tyre a few days after fitting.

    Choosing the right amount of sealant also depends on the user's priorities: adding more sealant results in better puncture protection, but makes the tyre heavier. With the milKit valve and spray system, which makes measuring and topping up sealant quick and easy, the right amount of sealant can be tested and optimised step by step without hassle.

    We recommend starting with the following quantities and optimising the right amount of sealant from there:

    • Road / gravel 40-80 ml / 1.4-2.7 oz
    • 26" MTB 60-80 ml / 2-2.7 oz
    • 27.5" MTB 80-100 ml / 2.7-3.4 oz
    • 29" MTB 100-120 ml / 3.4-4 oz
  • Can I make the sealant thinner by adding water?

    Our sealant is a little thicker than the sealant you may have used. It always remains homogeneous, so you don't have to worry about shaking the bottle before use or the particles not being evenly distributed in the tyre.

    The sealant covers the inside of the tyre nicely, but that also means less sealant flows to the bottom, which can then be measured with the milKit syringe. As a result, the "mobile" part of the sealant you measure will be smaller compared to the total amount of sealant in the tyre.

    If you want your sealant to be thinner, you can add up to 30% water to the sealant. This extends the sealant's life and makes it flow better to the bottom of the tyre, but it also slightly reduces the sealant's puncture resistance.

    It is always a trade-off between longevity and puncture resistance when it comes to sealants. You will have to figure out what is the right balance for you. But hey, that's exactly what the milKit spray system is there for, right? To help you understand what happens to the sealant in your tyre.

    An important fact when fitting a new tyre is that a significant amount of sealant "disappears" into the pores of the tyre. We recommend measuring how much sealant is left in your tyre a few days after fitting - this is the amount of sealant for best performance.

  • When should I replace my sealant?

    There are two reasons why you should check your sealant regularly:

    • Drying out of sealant
    • The sealant is getting old

    You should always have the amount recommended by the sealant manufacturer in your tyre. Over time, you will get a feel for how often you should check the sealant. Before a long ride or a holiday, it is always good to check the sealant to make sure your tubeless system is in good working order.

    Sealants also get old and lose their functionality. Old sealant can be recognised by a change in colour or when it starts to dissolve and the consistency looks more like water than new sealant. Old sealant should be removed from the tyre with the syringe. Mixing new with old sealant is not recommended.

    MilKit sealant does not dissolve and only thickens over time. Nevertheless, sealant should be replaced regularly to ensure the best performance.
    How can I wash the sealant off my clothes?

  • How can I wash the sealant off my clothes?

    One of the main advantages of our sealant is that it is water-soluble. So you can wash it off your tools and clothes with water. Make sure you wash the sealant while it is still liquid - once dry, it is made to be strong and durable - and therefore very difficult to remove from clothing.

  • How do I apply the rim tape properly?

    Our tubeless rim tape is made with pressure-sensitive adhesive. This means that pressure must be applied after taping for proper adhesion. When you inflate the tyre, the rim tape will adhere it to the rim.

  • At what temperature do I apply the rim tape?

    For taping, a higher temperature helps, but room temperature (>25°C) should work fine.

  • On which models can I attach an optical adapter?

    You can attach an optical adapter to the following models: Hero, Hero Small, Breeze, Breeze Small and Vision.
    What is the difference between the Vision and the Fusion.
    At first glance, both models match very hard on hard on each other. The Fusion sits very tightly on the face. The Vision sits slightly further (very minimally) from the face because you can attach an optical adapter to the Vision.


  • Are the lenses interchangeable?

    Yes they are! All lenses are interchangeable and can be ordered separately. See products to find out which lenses are compatible with which model.
