Alpinestars - S-M7 Core Helmet

Engineered for off-road racing, the Alpinestars S-M7 Helmet delivers a powerful combination of lightweight comfort, superior ventilation, and cutting-edge impact protection. Its sleek aerodynamic shell minimizes drag and avoids external features that could create load points in a crash, ensuring structural integrity and performance.

The S-M7 features Alpinestars' patented PLASMA technology, strategically integrated into the lower shell edges to reduce collarbone impact risks through advanced shock absorption. A curved shell profile further enhances safety by deflecting energy away from the skull, neck, and spine during impacts. It adds aerodynamic design: the s-m7’s aerodynamic profile design offers a smooth, streamlined shell free of any external channels and features that might act as a load point in an impact or compromise the overall integrity of the helmet’s construction. for confidence when terrain changes or the pace picks up. You get energy-deflecting design: the helmet’s curved shell is engineered to reduce friction and deflect impact forces away from the head, helping protect the skull, neck, and spine in the event of a crash. for confidence when terrain changes or the pace picks up.

Why We Like It:

Light and confidence-building. It keeps the noise and wiggle down so you can ride longer with less fatigue and more focus. On braking bumps and square edges it stays planted so you can relax your grip and ride looser. Highlights like The S-M7’s aerodynamic...

Why It’ll Work for You:

This helmet solves the usual hang‑ups: a fit that dials quickly, cooling you can feel at lower speeds, and impact management tuned for both straight‑on and off‑angle hits. If you’re new to the category, think of it as a simple upgrade in safety and comfort - easy to clean, easy to maintain, and shaped to work with goggles or sunglasses without fuss. It’s a practical, high‑coverage option for daily riding and bigger weekends when pace and terrain change.

Variants / Options:

Colors: Red Glossy, Orange/Blue Matte | Sizes from XS to 2X

Worked good then died at six months (Updated)
Worked good for a couple of months, then started to develop a lag between when you pressed a button on the remote, and when the TV would respond. If I moved the speaker blocking the TV’s IR receiver, and pointed the remote at it, it worked perfectly. Add the IR blaster back in and the delay returns. The delay kept getting longer and longer, sometimes 5 to 10 seconds. Then it just died. Would not pass any IR signals, even though the receiver and emitter both had power. Tried rebooting, changing communication channels to no avail. Out of Amazon return window. Manufacturer wants you do go through a troubleshooting process for warranty that is too complicated and time consuming. Customer Service Rep at Sewell send me a warranty replacement.

Nice Product and Customer Service
I ordered this BlastIR Wireless Pro IR Repeater from Sewell to replace a wired version of an IR repeater from another company. We have moved our TV on to a wall location and are in the process of hiding all the wiring out of sight behind walls and/or in a cabinet. We still have some wires to go, but this product has enabled us to eliminate the IR wiring all together. It's a real improvement in both looks and performance over the cheaper, wired version we originally tried. The BlasterIR's Receiver is the component that faces the room and receives the IR signal from our remote controls. It's small enough to fit in the space between our sound bar and the bottom of the TV. It's range is great for our room size (about 22' long and 18' wide) and picks up the remotes signal from a side angle that's almost parallel to the TV itself. The receiver is powered through one of the USB ports integrated into the TV (although the device itself supports either a USB or regular plug-in option). I haven't used them yet but Sewell appears to have provided a few options to help with affixing the IR devices in their final positions including some adhesive pads and a magnetic pad option as well. I'm still playing around with the permanent placement of the IR Blaster Emitter. It sits inside a closed cabinet and faces the concealed cable box receiver, router and DVR components. It retransmits the various IR signals it receives from the IR receiver by blasting that signal to anything it faces. I just placed it in the cabinet about 5" away from the devices I wanted to control, plugged it in and it worked with no other set up. So far the BlastIR is working seamlessly and with much better function response time than the cheaper IR version we'd tried at first. The lag time between when a button is pressed on the remote control and the action taking place on the device I'm communicating with is minimal. The emitter itself is plugged into an outlet on a surge protector powering the other in-cabinet devices, although it too could be powered via the provided USB connection if desired. As a note, we did experience a shipping issue during our ordering process. The order it self was processed quickly and shipped in a timely manner. However, there was an issue with our actual receipt of the product and the USPS who reported it delivered to our mailbox when in fact it had not been. Regardless, we reached out to Sewell directly and they quickly resolved the issue for us with no problems and in a timely manner. I would recommend both this IR Blaster Pro product as well as Sewell as a trusted company itself.

Does NOT Transmit Through Walls
Quick and easy setup! Works great within the room. However, will not work effectively between walls (i.e. - AV closet to living room).

Works perfectly - great product
My MBR TV set-up incorporates a cable box set up in a closet about 50 feet from the TV (hung over a fireplace). When it was set up the A/V used a wired infra-red set up that was wired thru the walls, under the floor, into the closet. Unfortunately some mice nibbled on the wiring and it does not work. I have tried everything including the Next Generation extender (over the years bought 6 of them for different TV's) and most recently the Startech. The Next Generation have not been updated in years and over time completely lose their ability to operate. No customer service at all; emails go into a black hole. I had high hopes for the Startech. Easy to set up and worked out of the box. The problem is the lag time. I could live with it when watching live TV, but it was totally impossible when it came to playing back programs from the DVR (which is cloud based). I was losing hope until I tried the Sewell Blaster. Took me less then 5 minutes to set up and it worked instantly. Little or no lag to speak of and I couldn't be happier. NB. Speaking of Sewell, the absolutely BEST way to control your HDMI based TV is the Sewell Direct SW-30062 Dual Band InjectIR sold by Amazon for $55. This is truly plug 'n play and operates with absolutely no lag. Bought 2 of these to operate TV's in my apartment where I had to hide boxes in closets. Well made, great instructions (coordinated with the devices) and I just love this product. I bought mine direct from Sewell ) same price) because I couldn't find them on Amazon when I needed them, but they have a great return policy and I'm told great C/S. If you can't use these then go for the Blaster.
