Engineered Foam Inserts
Cush Core is an engineered foam insert that sits inside a mountain bike tyre against the rim. It divides the inner volume of the tyre in half, with air underneath the tread as normal, and the Cush Core insert next to the rim. This provides an amazing damper for your tyre, reducing the sudden unwanted spring back that you get from normal pneumatic tyres. Cush Core absorbs shock, protecting your rim from sudden impacts and preventing pinch flats. The support it gives to sidewalls eliminates excessive tyre roll in corners, meaning you no longer have to run heavy, stiff tyres to get the casing stability required for aggressive riding. Cush Core also acts as a mechanical bead lock, anchoring the bead inside the rim so that tyre burping is highly unlikely.

Tubeless Ready And Waterproof
This system is designed to be used with tubeless-ready or tubeless converted mountain bike rims and tyres. The material is also waterproof, compatible with tubeless tyre sealant, and tuned for appropriate rebound feel. Unlike most puncture protection systems, this foam is not destroyed in a single impact. Its ability to withstand repeated impacts without damage is more typical of foams that weigh twice as much. Cush Core inserts are manufactured in Canada to tightly controlled quality standards.

Fully Custom Air Valves For Inserts
A customised tubeless air valve is included with each insert. The air valve allows air to move through the valve without becoming obstructed by the insert.

Unique Patent Pending Shape
Each Cush Core insert is born in a huge aluminium mould, a manufacturing process which allows us to create the unique, patent-pending shape. The shape helps secure the tyre to the rim, and extends well beyond the rim flange to protect against impacts from all angles. Cush Core's special shape also creates the lateral force against the tyre sidewalls that gives Cush Core the cornering stability and calm ride feel it's known for.

Australian Jared Graves Feedback On Cush Core
"Hey guys, just some quick feedback to let you know (and give thanks) that Cush Core definitely saved my race here in Madeira."
- Jared Graves, Team Specialized, Enduro World Series. Protects the rim from sudden impacts, prevents pinch flats . Supports the sidewall - increases cornering ability by eliminating excessive tyre roll . Run lighter tyres . Acts as a mechanical bead lock which stops burping .

Cush Core is compatible with your current tubeless tires and rims . Fits tyre widths 1.8" - 2.4" . Fits rims with internal width 22 - 32mm . If your wheels are not tubeless ready, rim sealing tape will be required . We recommend the use of tubeless tire sealant (such as Stan's) with Cush Core . Installation with certain tire & wheel combinations may require two people - one to work the tire levers, and another to hold the tire bead in the drop centre of the rim. Wire bead downhill tires are most likely to need extra help . 150 grams Durability Cush Core inserts are extremely durable. The foam is engineered to withstand repeated pounding and flexing without degradation. It does not absorb liquid and is not affected by tyre sealant. Service life will depend on your riding frequency, terrain, etc

One of the cleanest, most reliable creatine options out there
Flavor Name: Unflavored, Size: 30 Servings (Pack of 1)
I’ve tried quite a few creatine brands over the years, and the Thorne Creatine – Micronized Creatine Monohydrate Powder is easily one of the highest-quality options I’ve used. What stands out immediately is how clean and simple the formula is—just pure micronized creatine monohydrate with no fillers or additives. Each serving gives you the standard 5g dose, and it’s NSF Certified for Sport, which adds an extra layer of confidence around quality and purity. Mixability is excellent. Because it’s micronized, it dissolves much better than a lot of other creatine powders I’ve tried—no clumping or gritty texture, even in just water. Performance-wise, it does exactly what you want from a creatine: improved strength, better endurance during workouts, and faster recovery between sessions. Creatine monohydrate is also the most well-researched and proven form for performance and muscle gains, which is why I stick with it. Another big plus is that it’s completely unflavored, so it’s easy to mix into anything—protein shakes, pre-workout, or just water—without affecting taste. Overall, this is a no-frills, high-quality creatine that delivers exactly what you expect. If you’re looking for a clean, trusted supplement that just works, this is an easy recommendation.

Great Creatine Monohydrate That Doesn’t Give Me Cramps
Flavor Name: Unflavored, Size: 90 Servings (Pack of 1)
I switched over to creatine hcl, a more expensive and less studied version of creatine, after creatine monohydrate gave me terrible cramps. Then I tried this brand, and it is amazing: first creatine monohydrate that doesn’t give me cramps! Mixes well in my juice, and no residual taste. Also comes with a great quality blue scoop. Extremely high quality creatine.

Cellular energy boosters that protect the brain.
Flavor Name: Unflavored, Size: 90 Servings (Pack of 1)
Creatine monohydrate, a cellular energy enhancer that acts like armor protecting the brain, has been the subject of a groundbreaking study at the University of Sydney that has stunned the medical community. Vegetarians who added five grams of creatine to their daily diet each morning saw an average increase of fifteen points on IQ tests and a 40% improvement in working memory after just six weeks. This isn't just for fitness; it's about energizing brain cells. Creatine isn't just for muscles—a fact 99% of people don't understand. While the brain only accounts for 2% of total body weight, it consumes 20% of the body's energy. Creatine is essentially the fast energy currency needed for neurons to think and form memories. When you add creatine to your coffee, researchers at the University of Chichester discovered a remarkable phenomenon: caffeine, by increasing blood flow to the brain, increased the brain's absorption of creatine by 28%. Simultaneously, creatine completely eliminated the energy crash typically associated with caffeine by maintaining adenosine triphosphate (ATP) levels within neurons. A ten-year follow-up study of 6,000 adults over 60 found that those who consumed five grams of creatine daily experienced a 70% reduction in cognitive decline. MRI scans showed a 50% reduction in brain atrophy, and their reaction times remained at a level 20 years younger than their actual age. These scientific conclusions are astonishing. Creatine acts as a cellular buffering system, instantly replenishing ATP. More importantly, it protects brain cells from excitotoxicity, a process where neurons become exhausted due to overstimulation. Research published in the Journal of Neuroscience shows that creatine supplementation increases brain creatine levels by 39%, which is directly correlated with improved problem-solving abilities and emotional resilience. There's another amazing aspect that's rarely mentioned: research from the University of Utah found that creatine coffee reduced depressive symptoms by up to 52% in treatment-resistant cases because it energizes the mitochondria in brain cells that are often underperforming. Studies also show that people with higher brain creatine levels experience 60% less damage from traumatic brain injuries and recover faster. It's like a cellular airbag for neurons. The correct way to use creatine is to choose creatine monohydrate, which has been validated by over 6,000 studies. Because it doesn't dissolve easily in cold water, you need to stir it thoroughly into hot coffee. Add five grams, about one teaspoon, to your coffee every morning. Adding a little milk or cream is recommended, as the fat helps with absorption and can mask the grainy texture that some people dislike. Consistency is key when taking creatine; since it works through saturation, you need to take it daily for about four weeks to fully saturate your muscle and brain tissue, after which you can maintain the dosage daily. Unlike supplements that provide immediate effects, creatine is cumulative; most people experience improved endurance after seven to ten days, while the full cognitive benefits appear after three to four weeks. Some people use a loading phase of twenty grams per day in divided doses during the first week to achieve saturation faster, but studies show this is not necessary and may cause temporary water retention. Quality is also important; it's recommended to look for brands that have been tested for purity to avoid stomach upset or headaches due to impurities. One thing to note about creatine in coffee is that because water is drawn into the muscle cells, you may gain two to four pounds in the first two weeks, but this is not fat, but rather improved cellular hydration. Multiple studies spanning up to twenty-one years have confirmed the safety of creatine, even showing improvements in kidney function indicators.

High quality and smooth
Flavor Name: Unflavored, Size: 90 Servings (Pack of 1)
This mixes really easily and is completely tasteless, which makes it easy to add to drinks. I personally use creatine more for the cognitive benefits than the muscle benefits, and I’ve noticed a positive difference since using it. I wanted a high-quality option and this one definitely feels like it. One thing I like is that it dissolves well and doesn’t have any gritty texture or weird aftertaste. I usually add it to my coffee and it blends in perfectly. I will even add it to smoothies or sometimes just in cold water and drink it. You can’t taste it. I’ve learned to combat the bloat by staying hydrated and drinking a lot of water. For me, drinking it with coffee was fine. But when I had it with tea, since that is a stronger diuretic for me, my stomach did feel bloated and uncomfortable. But I’ll definitely continue using it.
