In this edition of Knurled News, we’ve got a quick update on tariffs from Peter Keller, a handful of new releases from REP, Fringe, and Rogue, and we’ll kick things off with a few of the top current deals.

In the video below, Peter Keller give an update on the current status of the tariffs in the home gym industry. In general, he says that the situation is worse than last year.

REP Fitness released details on the Strive™ Air Bike, which introduces Variable Pitch Resistance (VPR™) to a traditional fan bike. Instead of resistance being driven only by cadence, the fan blade angle can be adjusted to change how the bike feels at a given output.

The bike is built around a steel frame with a dual-stage belt drive, multi-grip handles, and an adjustable seat. Standard workout metrics are displayed on the console, and the overall design appears aimed at users who want more control over conditioning intensity than a typical air bike.

The Strive™ Air Bike is currently available for pre-order, with shipping expected later this year.

Fringe Sport introduced the El Toro weight stack horn attachment as a way to increase loading on selectorized cable machines. It inserts into the weight stack’s selector pin and allows users to add standard Olympic plates, extending the effective resistance beyond the built-in stack on both the front and back.

The design uses dual, outward-facing horns to keep added weight balanced, which may help reduce uneven loading during heavier pulls or presses. The attachment is relatively lightweight and intended for straightforward setup, though compatibility depends on stack pin size and plate spacing.

It is currently available and shipping.

Rogue updated its USA-made aluminum collars with the 2.0 version, and the biggest day-to-day change is that they’re easier to open and close thanks to a smoother lever design. It’s not a redesign, but it’s a noticeable quality-of-life improvement if you’re moving collars on and off the bar a lot.

Both versions are CNC-machined from 6061 aluminum, designed for standard Olympic bar sleeves, and feature a rubber-lined interior to help protect the bar and plates. Each collar is roughly 1.5 inches wide, keeping them compact on the sleeve. The standard version weighs about 0.65 lb per pair, while the magnetic version is closer to 1 lb per pair due to the added hardware.

The magnetic version functions the same on the bar, but adds embedded magnets so the collars stick together or to a rack when not in use. It doesn’t change performance during lifts—just makes them easier to keep track of between sets.

Overall, it’s a small but practical update from Rogue Fitness, focused more on usability than adding new features.
