TSI Threshold Review

I remember when the first TSI deck came out. I was skeptical about it, but I put one on and experienced the wonderful feeling of a one piece deck. It felt so solid compared to a bolted razor. Years later, it got even better.

TSI makes a deck called the Threshold. I used a slightly different model than the normal one called a Hammerhead to test. The difference between a regular Threshold and a Hammerhead is the front of a Hammerhead is completely square to make it easier to nose blunt. The length of this deck is 21.5 inches. I wanted this longer deck because the longer it is, the more leverage you have to pull when you are jumping. This makes your jump height increase. Having ridden TSIʼs in the past, I knew how it was going to be weighted.

For me, TSI’s are always too back heavy because the back drop outs are almost square. Whenever I do spins with whips the back dips down and I’ll miss the catch. So I decided to mark the back off at more of an angle and trimmed it down, this solved the problem. I also determined that structurally, the top deck plate doesn’t add strength, it’s the side rails that do. So I decided to cut a hole in the middle of the deck to reduce the weight even more, and because it looks really cool to see the ground moving under your scooter when you ride.

The brake is adjustable in terms of itʼs distance to the wheel. I donʼt think the bend is correct because it isnʼt the shape of a scooter wheel. It doesn’t matter if the brake is close or far, it still doesnʼt stop correctly. If you put it close, the wheel grabs at the bottom of the brake and immediately locks up. If you move it away, when you press on the brake the wheel is only in contact with the top of the brake and doesnʼt slow down at all. I always had to re-bend my fenders when TSI made them out of aluminum so they felt right. Now that they are made of steel it is almost impossible. This is a minor problem that TSI might want to look into.

“At first I was scared to lean that far back when I hopped. When I got used to it though, it was like unlocking the flying suit on Mario.”

Once my deck was fully prepped to ride I went to the skatepark to test it out. I dropped in and did a frontside feeble and immediately slipped out. Not because the ledge was waxed but because this deck slides better than anything I have ever ridden. I also had to get used to the way the pop was on the deck.

On most decks there is a sweet spot after raising your front wheel off the ground and being ready to snap off your back wheel. This sweet spot maximizes the height of your hop when leveling out. The angle of this sweet spot is so much further back because the deck is longer and the front sits lower to the ground. At first I was scared to lean that far back when I hopped. When I got used to it though, it was like unlocking the flying suit on Mario.

Nose blunts and over crooks were harder to slide. There is so much surface on the front of the deck which means a lot more friction on a ledge. You just have to make sure that the ledge you are on is metal, waxed, and wide coping. Despite being harder to slide, the balance was much easier on nose blunts and over crooks. Doing 180 nose blunts on a quarter pipe, even though my momentum was still spinning, the deck was so locked in I was able to jump back in perfectly straight.

There is so much foot space because the head tube doesnʼt stretch on top of the deck for very long. Even if decks of different manufacturers were this same length, it wouldnʼt feel the same because the distance of foot space would be smaller. Because there is so much foot space I sometimes shuffle my feet up and down the deck depending on what trick I am doing.

I would highly recommend this deck not only because of my satisfaction with how it performs, but also because TSI is a rider owned company that was made out of their passion for making a scooter deck that finally works for scooter riding.

Other than the weight at the back this deck is balanced perfectly. This deck will slide on anything. The brake needs work on the bend design. The welds are perfect. The headset cups and axle holes are precise.
