The original, which launched in 2024, wasn’t that big to begin with. Now, there’s an even smaller option for keeping tabs on your bicycle’s tire pressure with the Outrider TL Mini.
The design is the same, using a small transmitter plate that sits inside your rim, and it still works with almost any standard Presta tubeless valve stem.
What’s new is the size – it’s smaller to fit inside more rims, and it’s just 3.7g per wheel. They say it’s recommended for symmetric rims with a 19mm internal width, or asymmetric rims with 23mm internal width.
It works up to 125psi (which is way higher than anyone is, or should be, running in a tubeless setup). Its electronics are completely sealed in epoxy, with a chemically-resistant membrane over the pressure sensor to repel liquids, so add all the tire sealant you want. It’s even compatible with tire inserts.
The wireless communication lets it talk to Garmin and Hammerhead computers (as well as most Garmin smart watches), as well as their iOS and Android apps. At launch, it’s not compatible with Wahoo.
It does more than just show real-time tire pressure, though. Features include:
- Customizable low pressure alerts
- Tire pressure timeline from your ride
- +/- 2% accuracy
The battery lasts for up to 2,000 hours of ride time, which is good because it’s not replaceable or rechargeable. But if you typically ride two hours, that’s 1,000 rides, or about three years of riding every single day. They say that’s more like 5-10 years for most riders. Soooo… it’s probably fine.
MSRP is $69 for the pair. You’ll need to supply your own valve stems with removable gaskets… you have to sandwich the monitor between the valve stem’s base and the gasket to create a seal on your rim. It’s available for pre-order now and ships in June 2026.
