Alienation BMX TCS (Tubeless) Mischief Rim

With the proliferation of carbon fiber BMX race frames these days bringing the weight of BMX race bikes down it’s said that wheels and reducing rotating weight will be the next craze. I feel that this has already been happening for quite some time. Alienation have been a leader in BMX rims since they hit the market in 2006. They aren’t the kind of company that sits on their hands, they are driven by making the best products available and just when you think they have come up with the perfect rim, they are already working on the next one.

The TCS Mischief rim is Alienation’s latest front specific rim, it’s been available for a while now, and normally I’d be all over it being a new product. The problem with Alienation rims is they are so good that I just couldn’t find a good enough excuse to replace my existing wheel set. After two and a half years of abuse my Alienation Stay Strong Skylark/Runaway combo still look great and run perfectly true. Even on the odd occasion where I have blown spokes on the drive side of my back wheel it remained perfectly straight. It’s one of the many reasons I personally choose Alienation rims, they are far superior to any other rim I have ever used in my 30 plus years of BMXing. It’s lucky for Alienation that I have a number of bikes that I use regularly otherwise they would just about engineer themselves out of business.

I first looked at the TCS (Tubeless) system early in the piece and I’m just as impressed with them today as I was three and a half years ago. Sure there’s still no sign of the tubeless tires yet, but I hear they are just around the corner. One misconception of the TCS system is that they are a tubeless rim for tubeless tires. TCS actually stands for Tubeless Compatible System. While they are compatible with the TCS tubeless tires they are also compatible with everyday standard pneumatic tires like the popular Tioga PowerBlock and so on. One thing I noticed is they have two valve holes. One for TCS valves and one for the standard Schrader/car valve style. While it didn’t seem to make too much sense to start off with I’m sure it will all make sense once the TCS tires are released.

Is it too early to come up with another tubeless compatible rim before the tires are available? Heck no! If Alienation can come up with the ultimate rims for when their R1 and F1 tires are available it makes it easier to be ready for the game changing tires and it would make it even better to make the switch to the best possible rim combo after the tires are finally made available.

Weight

The Alienation Mischief rim really is one for the weight weenies, weighing in at a scant 290 grams or 10.2 ounces the Mischief is the lightest front rim on the market and weighs in at the same weight as the Speedline RCR Carbon rim, but a much more appealing price tag.

The surprise for me is that the Mischief is the same weight as Speedline’s RCR carbon rim.

How do they ride?

The Alienation Mischief rim is up for anything you can throw at it. It does feel light and strong and there are no signs of flex. I’ve heard of heavy crashes that resulted in broken bones with the bike cartwheeling away but the rim stayed true and all ready to ride after the healing process.

The Final Word

Compared to other rims the Mischief is superior in strength and the lightest on the market. While it may be a little more expensive than other alloy rims, it’s no where near the cost of the carbon options. After taking a close look at the Mischief rim I now know I should have grabbed one of these rims much earlier.

Comments

  • The Alienation Mischief rims are made from 6069 T6 alloy which provides extra strength, they are tubeless compatible, and the lightest rim on the market, they cost a little more than most alloy rims but they are light years ahead of the others by design. Like all Alienation products they are built to last!
  • They are simply the lightest rim on the market!
  • You couldn’t ask for more from a rim.
  • As always Alienation have put in a lot of effort to the looks and the finish of the rim. Second to none. I’m sure that there will be people out there chasing additional colour options, but the matt black looks great to me.
