Sometimes there's no way around technical jargon when talking about the advantages and differences between our various indoor training possibilities. So we figured we'd put all the weird words in one place for your reference.
Think we missed something? Let us know.
A resistance unit on an indoor bicycle trainer is the physical unit on the trainer that generates the resistance against which the rider works.
In the most basic sense, bike trainers are made of two elements: a physical aspect and a mathematical one. When it comes to your physical ride, that is where the resistance unit comes into play.
Here at CycleOps, each type of resistance unit uses a different method to create that real-ride feel. The resistance unit also acts as your trainer's "motor," so to speak, and can be removed from the frame for servicing or an upgrade — if you so wish.
Not every trainer offers the same type of resistance or real-road feel. Here's a brief overview to help you make your pick.
Resistance curves generate the math part of your indoor bicycle trainer experience. Using factors like wheel speed, PowerTuned technology, and cadence rate, they all work together with one of the five types of resistance units above to bring a realistic ride indoors.
Not all bike trainers create resistance the same way. Here's a brief breakdown to help you choose which will work best for you.

A term most often seen in our trainer product descriptions, PowerTuned means that a specific trainer features a resistance curve created using PowerTap's technology to produce the widest range of resistance at real world speeds. Each resistance unit is also tested using a PowerTap to ensure a consistent resistance curve from one to the next.
Wheel size refers to the size of your bike’s wheel. Finding the wheel size is as simple as its definition, simply check the outer sidewall of your wheel’s tire. Knowing this information helps you know if your bike will be compatible with our indoor trainers.
This innovative feature can be found on most of our indoor trainers. It is yellow and functions similar to a gas cap as it clicks until it has reached the perfect tension between your rear wheel and resistance unit roller.

Our Pro Series frames are foldable, come preassembled out of the box, and feature a one-sided leg adjuster so that you can easily ride on any surface.
All of our trainers come with our trainer skewer, and for good reason — it provides the best bike-to-trainer fit.
Using our trainer skewer will also reduce the wear and tear on your road skewer (which is important when you're zooming down a hill at 30 mph) and allows bikes with nuts to be compatible with our full trainer line.
Plus, our trainer skewer is robust enough to stay in your bike year-round – a key time saver for those pre-race warm-up sessions.

A trainer tire is a bicycle tire specifically designed to withstand the unique elements associated with using an indoor bike trainer.
For instance, did you know that riding indoors on a trainer/roller will generate more friction than when riding outdoors? It's true. And most outdoor tires are not designed to handle that amount of excess heat. That's why we make and recommend the use of training specific tires.

Products that use Bluetooth Smart technology communicate with Bluetooth Smart Ready products, such as the iPhone 4S or higher and on iPad version 3 or higher. To use Android devices you must have the most recent version of OS or Jelly Bean 4.3. Currently, the PowerTap Mobile App is only available for Apple Products. Bluetooth Smart is also integrated on most new Windows 8 PC systems.
ANT+ FE-C enabled devices communicate with other devices that contain ANT+ sensors.
In the cycling world, dual-band technology is defined as products that communicate via Bluetooth Smart and ANT+. Using a product that features dual-band technology allows the athlete to choose which communication protocol that works best for them, their training software of choice and/or accessories of choice.
Learn more about Bluetooth, ANT+ and dual-band protocols from Saris Cycling Group's Chief Electrical Engineer, Ed Watson.
