AC Performance Systems Product Review

Three years ago the Jim and Dave Castillo, creators of CTI knee braces and Asterisk knee braces, continued their growth of creating innovative motocross products such as the AC System. You know those weird nose magnets we saw on the pro guys in Supercross were paired with a foam piece of material that was locked on to the bridge of MX goggles and when the two magnets connected, the airflow through the nostrils were increased. However through more testing and development with the system, the Castillo’s went to work on a much simpler design that could be used not only in moto, but in other sports as well. The updated/new AC Performance Systems retains the same special nasal stickers that contain a small magnetic piece, but the anchor of the part is the plastic noseband that lays over the bridge of the nose and opens the nostrils. 




Does the AC Performance System really work and are you able to feel a difference on the track? Even though Dave was up my ass about getting him some feedback, I took my time with this and really tested this product in all facets of my life. I used it when I rode, went running, cycling, rowing, skiing, sleeping and even other extra curricular activities that I will spare you the details on. Here are a breakdown of some of my findings: 




 Putting on the AC Performance Systems is simple. In the box you will find alcohol wipes, magnetic applicator, nose strips and the AC band itself. Simply clean off your nose using the alcohol wipes then install one nose strip with the magnetic applicator (on each side of your nose) and fit the AC band up with the magnets and thats it. Once you do this you will feel like your nostrils just got a freshly tuned port job. It’s quite shocking when you first put it on. I was so stoked on how much air I got through my nose I had everyone in my family put one on just so they could see! Riding with the AC Systems takes a couple laps to get used to and almost helps you remember to breathe more through your nose than with your mouth (which is how our body is designed to breathe). This is something I try to do twice a lap when I ride. Find two spots on the track where you're most comfortable and pick those spots to really take deep breaths. The AC System really helped me remember to do that and let me intake deeper, more fulfilling breaths. 




Now since you all know that I am all about “feeling” when it comes to testing, I can say that the feeling that I got (while riding) was that I didn't get as winded as I normally do in a thirty minute moto. I actually called bullshit on myself, so I whipped out the heart rate monitor and over the course of just over a month, averaged out my heart rate without using the AC Systems one moto and with the AC Systems one moto (basically I would do one moto with it on and one moto without it). It comes to find out that when I averaged out the numbers my heart rate was always 5-7 beats per minute lower (per moto) with the AC Systems on. You might say “well shit Keefer, that isn't that much”, but it really is in the world of aerobic performance. Does it help with arm pump? I really can’t tell you that because I usually don't ever get that much arm pump to begin with. However, lowering your heart rate can’t hurt when pushing yourself in a long moto. 


I have grown accustomed to using the AC Systems when I train as well and find my training sessions (mostly running, rowing, cycling) are also 3-5 beats per minute lower than without using the AC Systems. Now that my nose/body is accustomed to wearing it, it is tough when I don’t wear it because I can feel my nostrils blocking my air passageway at times. For basically $35.00 it is an inexpensive way to get more out of your breathing in my opinion. Is it some miracle piece of athletic equipment that you must have? Of course not, but if you’re looking to maybe experiment with getting an edge on someone athletically, it doesn't hurt, I do know that. 


Note: I have a somewhat of a big nose and I wear a size 1. The AC System comes in sizes 0,1,2,3 so unless you're Pinocchio go with a size 1 or 2. My 12 year old son wears a 0 and it fits him great.

I ride a lot! Sometimes many consecutive days in a row. Now all of you out there going WHAAAAAAAAAAA he has to ride a dirt bike WHAAAAAAAAAAAAA, probably never had to ride more than a few days in a row. Sometimes I have to ride a couple weeks in a row and let me tell you that is hard on my ass!  



 I have been using ChafeZone when I know I have long days on the bike or maybe coming back from not riding in a while. I stumbled on this stuff over a year ago and it has been one of the first things I put in my gear bag when I go to the track. ChafeZone prevents monkey butt, blisters and chafing. How you ask? I don’t know, but MedZone’s ChafeZone is made up of oleic acid, safflower seed oil, linoleum acid, palmitic acid, myristic acid and brag officinalis seed oil.


I first started using ChafeZone on my hands on long durability testing days to prevent from getting gnarly blisters. It worked so good, I then started to put it in other key areas to prevent me from getting monkey butt and rashes on my rear end. I would literally get holes in my butt from aggressive gripper seats (think Husqvarna and KTM 450 Factory Edition seats) and would have to stand up on the pegs by late afternoon on long testing days. Sitting down would just make me cringe! Once I decided to try ChafeZone, I would religiously put it on in the morning before I left for the track and would be good to go for the duration of the day. ChafeZone goes on your body as a solid but quickly turns into a liquid that leaves a slippery feeling. Sliding your gloves on your hands after applying is kind of a foreign feeling, but once out on the track I quickly forgot about it and it didn’t bother me. 

The good news is that once you apply the stick to the areas you want, it will not rub off all day. The bad news is that it is a pain to get off and takes some effort to wash away. A shower once at home will handle the residue, but if you want it off while you’re at the track, it is tough to get off. You must use soap and water and really get aggressive to get the stuff off. But hey the stuff works and its the only product I use to keep me from getting blisters and chafing. A 1.5 ounce stick ($12.99) lasted me about two months (riding four to five times per week). If you’re a die hard rider and want to log the motos or the miles this ChafeZone stuff works very well. It’s easy to stick in your gear bag, just make sure it doesn’t get to hot or it can melt. Getting it off your gear bag is even harder than getting it off your skin. 



You can go to to get yours or you can go to Amazon and  order it through there. Thank me later!

Fasst Company Spoke Torque Wrench

As much as I love riding and testing products, working on bikes is not something I really want to do all day. I would say I am a middle of the pack vet intermediate mechanic and I like tools that make my life easier. The Fasst Company spoke torque wrench has made checking my spokes tension much easier and more accurate. The spoke torque wrench kit comes with 12 heads that fit all spoke nipples of all makes and models.



The Fasst wrench comes preset at 48 inch-pounds, but can be adjusted from 10 to 100 inch-pounds. The wrench is easy to use as you simply tighten your spoke until you hear/feel a click. A good rule of thumb is to tighten every third spoke, which will take you three revolutions of the wheel. The guesswork of how much tension you are using on each spoke is gone and I have kept my wheels better trued longer than I have using a traditional spoke wrench. The handle is larger for an easy grip, and each head is wide and will not slip once on the spoke. You can even get custom laser etching on the wrench for an extra $19.99, which of course I did for the cool factor. I mean come on! 



 The Fasst Company torque spoke wrench will cost you a pretty penny at $255.87 (for the wrench and all 12 heads), but it can be used for every bike in your garage. Everyone has that one buddy that needs to borrow a spoke wrench at the track right? Well...Once he uses this sucker he will most likely fall in love with it and will go buy his own. You can thank me through email at later. If you don’t need all 12 heads and you just want the wrench, it is $99.99; and any extra head will cost you $12.99. This is by far my favorite tool in my toolbox. You can go to to get yours.

MindFX Science Performance Pro Supplement 


Before I start speaking about this review, I want to make it clear that I do not believe in witchcraft or voodoo. I was raised that only hard work and dedication were the formulas to success. There were no shortcuts in life, just like there are no shortcuts in getting better on a dirt bike or getting in shape. Sweat, effort, consistency and a lot of riding is how you get faster and more fitness for this dirt bike thing. I was reluctant to try MindFX because I thought this was another snake oil pitch by some guy trying to make a buck. If I wanted to drink something in between motos, I would just drink some good old fashion H2O and maybe a gatorade to get some sugar in me. However, when I tried MindFX Performance Pro for the first time I felt something a little different with my body during a 30 minute moto. Before I get to what I felt like after I used MindFX Performance Pro, let me tell you what it is all about. 



MindFX Science was created by Kevin McCarthy as a healthy alternative to the highly caffeinated energy drinks that some of us grew up on, pre-workouts mixes and even some ADHD drugs. MindFX claims to achieve this result naturally via the use of adaptogenic herbs, strategic use of vitamins, minerals and natural flavoring.

– Rhodiola, our adaptogen, increases vitality and immunity and reduces fatigue and exhaustion in prolonged stressful situations.

– Siberian ginseng, another adaptogen, increases mood and physical performance.

– Organic Beet Powder helps with oxygen uptake due to the high nitrate content.

– Vitamin B12 helps support the body’s ATP production, the energy our cells run on.

– Theobromine used to relax the bronchial muscles in the lungs, which increases oxygen flow to the brain. In addition to its stimulant properties, theobromine

also promotes heart health, good cholesterol levels, and more.

– Caffeine (low 75mg) as a natural stimulant has been associated with positive effects on the brain and an array of health benefits.

– Ginko Biloba acts to enhance oxygen utilization and thus improves memory, concentration, and other mental faculties.

MindFX original formula was developed for competitive athletes and designed to be a blend of all natural neuronutrients that increase focus and concentration.

MindFX Performance Pro was developed with some of the most fittest athletes on the planet that required additional nutrients like Vitamin C and electrolytes to help sustain mental focus and reduce fatigue.

MindFX powdered drink mix uses water as its delivery system ensuring a healthy balance of hydration.

So now that you have the gist of what this product is, how did it work on me? I ride, test, type, talk and train all throughout the week. That is my program. I don’t drink alcohol, I don’t party, I am actually quite boring, just ask my wife! I just like to ride! Sometimes I have to do some durability tests that involve a crap ton of motos per day and that sometimes happens three to four times per week! Again, like I said, I ride a lot! So I thought what the hell? Ill try this stuff out. I am the kind of guy who will have 90 calorie Coca-Cola after a long day of riding now and again, but otherwise that is the only super sugary thing I drink within my diet. I used one packet of MindFX Performance Pro and mixed it in a 16 ounce bottle of water and downed it after my first 20 minute moto. On this particular day I had to do five 20 minute sessions and I could feel a little more spunk and focus rolling into the next few motos that I did. Now I thought to myself,  “this must be a placebo effect right”? I tried another packet of MindFX on the very next test day and felt the same thing. It’s not like I gained superhuman strength and it lowered my heart rate, but I did feel like I could focus on my line choices better when I was pushing. The most important thing that MindFX DIDN’T DO was give me a sugar high/caffeine crash. I was waiting for the lull in my performance enhancement after a couple hours, but it never really came. Again, I really want to stress that this isn't a cure all for fatigue, but it does help me get over the hump on long strenuous days of riding. I like my cup of coffee in the morning and that gets me bump started for the day. I look at MindFX as my “coffee” bump when I go ride now. The directions say not to take more than three packets per day and the most I have taken was two packets in one day. One when I was testing and one when I got home, before I headed on my mountain bike ride. 



I am happy to purchase products that work for me and MindFX Performance Pro works for me. A packet of 20 sticks is $29.95 and it comes in two flavors (Mixed Berry and Orange Mango).  My favorite flavor is mixed berry as it doesn't have a harsh taste to it. Orange mango tastes decent, but mixed berry is just a better flavor for me. It is easy to down/digest and not something you will make a bitter beer face, after you taste it. MindFX makes another blend for the non-athlete and it is called “Performance”. You can do your own research and check it out for yourself over at
