Marvel Compound Tires Airless 700x20c review

     If there was ever a zombie apocalypse the only tire I think that I would ever use would be these Marvel Compound airless tires.

     I have been riding these tires on my spare bike for close to 6 months now and I would like to spread a bit of information on these puppies. They have lasted the full 6 months without even a hiccup. Airless tires are not widely used in the current cycling industry and I think they deserve a moment of your attention. There are many benefits to riding these tire for both the avid cyclist and the casual rider.

Pros:

- Longevity

 The Marvel Compound airless tires can last a ridiculously large amount of time on a bike. If you rotate these tires their lifespan can be extended even further! I have had these tires for around 6 months with heavy use and they are still kicking. I have even done a couple of centuries on them, I actually broke them in on a century! I generally go through tires every 3-4 months and I commute everywhere on them. It's currently on my commuter bike and I love riding them when I get too lazy to check up on my main. I rode tires regularly for a good 3-4 months straight before popping them on my other steed. My normal commute is around 12-18 miles a day, 4 to 5 times a week.

- Less maintenance

After the initial break in and mounting of the tires these babies are good to go. I am a man without much free time in this world and if I can remove one step to get where I am going then it is always a plus for me. These tires have saved me from so much debris in the road that would have normally punctured a tire.

- Marvel Compound Tires come in a variety of different sizes to suit your needs. 
I personally picked the 700x20c 120psi version of the tires and it might have been a little bit too hard for my conditions. I live in the countryside on the outskirts of Jacksonville, FL and for some reason thought that my roads would be fit for a higher psi tires if I could remove the puncture factor from the equation. You still feel the resistance from bumps in the road, they just can't put you in danger anymore. If I could do this again for my road conditions I would pick the 90-100 psi versions instead. If you live on nice roads these are a perfect option and I would highly recommend them. Marvel Compound makes tires for all sorts of bikes so please be sure to check them out.

- Great for commuting

I use these tires on my bike to get to my day job. That's about 12-18 miles total out of the day and it's perfect for that ride. I really like that I can always pop on these and they are ready to roll. After a bit of rain I just grease my chain and I'm good to go.

- never going to get a flat
I will reiterate that these tires have saved me from so many flats. I am a very reckless rider and these keep my confidence in high gear! I have pulled all sorts of stuff out of the tires and they perform well to this date. Pot holes and nails can kiss my booty!!
- Great for trainers/rollers
If you use a trainer then this is pretty much all you need. They last forever and will be consistent every time you use them. Great to track your progress in stamina and power.

- Value

The tires are relatively inexpensive and last for a very long time. I do not always have extra money and every paycheck counts for me. The extra dime that I save always helps and adds up to more meals or provisions for myself. When you add up the tubes and tires that you don't have to buy from punctures it really adds up!

- Extremely high psi

 These are great for people that are learning fixed gear mechanics, and anyone that is looking for a tire that can run extremely hard without fear of a blowout.
I would recommend a wider tire than the ones that I use so you can have a wider skid patch rather than a longer one. A gear ratio of 48x17 on 700c tires should do the trick for flat ground and constant use, it should provide for the large amount of ski patches that you will need. This will give even wear of the tire and provide a longer lifespan for it as well. Since the tires are a higher psi they are easier to skid. Braking distance is increased a bit but if you are learning fixed gear mechanics then it will make you more confident.  For any bicycle that can coast you are more than welcome to use any gear ratio that you would like with these tires. Skid patch dilemmas generally only occur on setups that are brakeless and fixed gear.
Note: Make sure that you pick a tire for your specific rim width.

Cons:

-Break in time

After around 100-200 miles (break in time) you have to true your wheel. Everyone should be doing maintenance on their bikes but it is imperative that you do this with an airless tire. The tires breaks in with the wheel and will find the portions in which it is untrue. After that you are good to go.
- rotating wheel to provide more life All tires will live longer if you rotate them before they are unfit for use at around 1/2 thread use in the back tire it is always good to rotate them. This will provide the longest lifespan of your tires. After 100-200 miles you have to true your rim again because the tire breaks in again.

-Tires are rim specific

The tire size of airless tires are limited to rim width and run better on perfectly suited rims. You have less options but specific tires for suited rims have the benefit of added performance.

- To use on a brakeless fixed gear bicycle you have to run a higher skid patch ratio.

 Before I talk about this I would like mention that this only applies if you ride a fixed gear bicycle all other bicycles will perform extremely well on these tires in all conditions. If you run these tires on a gear ratio with a low skid patches available then the tires will wear uneven. This will effect lifespan and performance of tire.

- Best used on shorter distances.

These tires can feel stiffer than your normal tire and take a moment to get used to them. You can ride far on them, (I have ridden a couple centuries on them and the road kicked my butt) these tires perform better on short distances. I cannot say that for all Marvel Compound tires but specifically these 120 psi rated ones are best used in good road conditions and short burst distances. If you have a 25 mile or less commute in your day then these tires will perform beautifully.

- Mounting tires have a learning curve.

Mounting these tires are different and they are completely new to anything that you have ever used before. The best method is to use zip ties for each 1/4 of the tire to brace the tire and wheel. When the first bit of the tire gets seated into the rim you should zip tie that contact point there and then. If you can learn to zip tie contact points then the tire can be easily mounted like as if you were using a normal tire. I recommend riding extremely defensively during the break in of your tires just to be safe. First 10-15 miles are best used to see how far you can lean and see what kind of setup you would like to run on your bike with your tires. If you ride around in both clockwise and counterclockwise circles as soon as you mount your tires it can help break in your tires to seat into your bike rim. A trick that I used is to lightly coat the tire in wd-40 where the inner tire contacts the rim. This helps with initial mounting of the tire and creates more friction on the contact point of the rim and tire after the WD-40 dries.

Conclusion:

     These tires are an insane value and I recommend that you at least try a set. Even if you ended up not enjoying these on your bike the tires themselves would save you from buying 3-4 sets of tires after their entire lifespan. The tires pay for themselves and you can always go back to other tires if you so choose to. The set of Marvel Compound tires can make you more confident to travel unknown roads and new routes. These tires even help me when I'm sprinting home in the dark. I cannot see everything in the unlit roads on my way home from work most of the nights and these tires have saved me many times from having flats in dangerous places. I can see myself buying another set in the future when these tires are fully destroyed. (I will let you know when these finally give out on me, I am pretty curious myself to see how long these will last.)

     I have put these tires through hell. Everything that I own generally gets used to full extent and I am happy that these tires have withstood all of the abuse that I have given them. My setups are work horses and I  commute almost solely by bicycle. If you get a chance give these tires a try and I bet you will find many uses for the tires on your setups. I would also like to mention that if I had a pair of these when I was growing up my boundaries would have been limitless in my town.

  Have a good day and thank you for reading.
