An aerodynamically honed stem with adjustable length and angle to optimize your position. Linking handlebar to fork, the stem was developed with Team Dimension Data for the refined ride response and control needed in a critical area of the bike.


This stem is intended for negative drop only and cannot be flipped or reversed in a positive rise. The rider makes up 80-90% of total aero drag, so refining your position can produce some of the biggest gains of all. Further, the shape of the stem, plus the ability to eliminate headset spacers, allows for cleaner airflow at the front of the bike, producing valuable drag savings.


Created in conjunction with Team Dimension Data, the stem delivers the confident and responsive ride feel desired by the best riders in the world.

Good deal for the price
Style: 80 mil 18 SqFt
The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil

Excellent Sound Deadening Material!
Style: 10 SqFt, Style: 10 SqFt
I installed Kilmat Sound Deadening in my truck, and I’m extremely impressed with the results. The material is thick, pliable, and easy to cut to fit doors, floor panels. It sticks very well to metal surfaces and doesn’t peel, even after heating it slightly to make it more flexible. After installation, I immediately noticed a reduction in road noise and vibrations. Worth the money!!

A Must Have For Car Restorations!
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
I have been installing this matting in my 74 Datsun 260Z restore and very pleased with the ease of application and overall quality. My car has bedliner coating inside and this stuff sticks extremely well and is easy to trim and shape as well. I have just started installing it and using the rollers to work it in place but I can already tell a difference with just the little bit I have added....has reduced the resonance in the metal already. It's not a fast process but know it will be very rewarding once complete.

Excellent Tool for Sound Deadening and More!
This Bearing Equipped Wheel Roller is a fantastic tool that's proven incredibly useful for more than just car audio. I originally got it for installing sound deadening mat in my vehicle, and it worked perfectly. The bearing-equipped roller applies nice, even pressure, making sure the mat adheres properly without bubbles or wrinkles. It feels solid in your hand and rolls smoothly, even in tighter spots. Beyond car audio, I've used it for applying heat abatement mat and even for smoothing out seams on vinyl projects. The PU (polyurethane) material of the roller is great because it's durable but doesn't mar the surface you're working on. It's much more effective than just using your hands or a makeshift tool. Great value, with a solid feel but not heavy. It's a simple tool, but the quality of the build and the smooth operation make a big difference. If you're doing any kind of sound deadening, heat shielding, or even wallpaper/vinyl application, this roller is a must-have. It makes the job much easier and ensures a professional finish. Highly recommend it!
