You may already be familiar with some of our previous collaborations with Jason Belmonte. From the PRO-Motion™ came the reputable Piston Core, a fantastically balanced shape that works for almost everyone and with any layout you can imagine. And to expand upon the ball motion already created by this phenomenal core shape, we explored a wide variety of coverstock options to create the most powerful ball ever in the Signature™ Line.To showcase the backend potential, we selected several variations of the Reactor™ family of coverstocks as they are the most responsive in the industry. As we worked through testing, it was clear that R2S was the best option for this one! “You want better carry? Then you need angle into the pocket. The Trend is what you have been waiting for,“ said Jason Belmonte. And no matter what your rev rate or how many hands you use to bowl, the Trend will give you a quicker response, more defined breakpoint, just what you need for better carry.

The engine of change

The Piston core brings with it months of testing and validation in conjunction with the best player of our time: Jason Belmonte. Developed specifically for his line, the Piston Core creates separate helical archs that make the shape corkscrew as it tumbles. You can see the channels on the sides of the Piston Core and the large band through the equator which displaces the mass in a very specific way.

The R2S delivers a perfect balance

R2S is synonymous with some of the most successful balls in recent history like the Hy-Road, Frantic, and the IQ Tour. It is renowned for clearing the front part of the lane with an unprecedented movement on the backend. The consistency of this shell through the heads is something to be marveled at.

Trend by Roto Grip Rick
Storm TREND - 35 x 3 5/8th x 50 at 1500 grit polished
Coverstock: R2S Pearl Reactive
Core: Piston Core
With the proven R2S cover and the newer piston core from the Pro-Motion this ball for me fit between the Parallax and my Storm !Q Emerald. Stronger in the front and mid lane and "striking" well in recovery when bowling on SPL with a 44ft house pattern, noticed that where it seemed the Emerald was getting lazy, it is the next step up in my Storm bag. I really like that they made this ball when they did, with my recovery still going on, I need taller cores to have the ball get down the lane. This one was a no brainer for me to use a strong pin layout - did not have to play with the cover like I did with the Parallax. Really super ball for bowlers that are looking for that special middle piece for their 3 ball arsenal or in their tournament bag.

The new Trend Pearl is the latest addition to the Jason Belmonte Signature Line. It has a great color mix and is eye catching for regular bowlers and Belmo fans alike. This has been our shops best received of the Belmo Signature line. I feel this ball fits a wider variety of bowlers and gives a more familiar look on the lanes than previous in the Belmonte Line of balls. The Trend has the same core as the Pro Motion but that is where the similarities end. The Trend is much cleaner through the front and more angular on the back than the Pro Motion. The Trend is very good on a typical house shot. I get a nice back end move on mind but some bowlers are getting more of a flip reaction on theirs. The Trend still maintains predictability most likely due to the core. I have a lower rev rate and prefer using this ball when keeping angles in front of me but I have drilled the Trend for higher rev bowlers who have no trouble getting deep with it. I feel this is a nice addition to the Signature line and will help people look forward to the next Belmo entry.

The Trend works great on house conditions.
The color mix is excellent.
The Trend is a good addition to the Signature Line.

Trend is amazing
I love the ball I am pretty new a two hands but this is what I would Suggest for new to handers. But my question is what ball cleaner should I use for the trend

Never fails to perform!
I'm a newbie to bowling, been casually bowling for the past two years in Singapore. Ever since I have gotten this ball, it never fails to perform!
My layout is 4-4-2, and the ball path predictable and helpful in my bowling journey.

A new Trend!
Hey everyone, this is Storm staff member Josh Shoemaker here with another ball review for the Storm Trend. As always, I would like to thank Storm for providing the equipment I use every time I step out onto the lanes and logo infusion for making sure I always look good no matter what! Today I will be bowling on a standard 44’ house shot. The Trend is the latest Storm and Jason Belmonte collaboration. It features the same piston weight block found in the Promotion but is now wrapped in R2S pearl. The Trend comes out of the box with Storms signature 1500 grit polished finish. The Promotion was known for its super slow response time with having a SPEC cover. The Trend is at the complete other end of the spectrum and provides a much cleaner and faster response to friction. Although the core/cover is very similar to a Hyroad pearl, I find the Trend to be a littler earlier and straighter off the end of the pattern. When compared to the OG Hyroad, the Trend is slightly straighter off the end of the pattern as well as being a touch weaker overall. The Trend is now available for purchase from any Storm VIP pro shop!
