Rally vs Vector 3/3S | Comparing the Latest Garmin Power Meter Upgrade

We Compare the Vector™ 3/3S with the New Rally™ Family of
Pedal-Based Power Meters

Garmin Rally Upgrades
-SHORT VERSION -

Short on time? Here's the 3 things you need to know:

  • Garmin power pedals now offered in three (3) models each with SINGLE-SENSING (RS/RK/XC 100) and DUAL-SENSING (RS/RK/XC 200).
  • Vector 3/3S battery/consistency issues are 100% fixed thanks to extensive amounts of testing.
  • Should You Buy? - that depends on if...
    • "I DON'T have power pedals yet" - 100% yes you should buy. The accuracy you get from measuring power directly from the pedals is unparalleled. Plus with the bugs fixed AND being able to choose between Road and Mountain ... PLUS the seamless integration with Edge + the Garmin ecosystem ... No brainer. Once you start training with watts, you never go back. We promise. Click here to shop Rally RS/RK or XC.
    • "I already have the Vector 3 (with the new battery door)" - There's no need to upgrade UNLESS you want to move from LOOK Keo (Vector 3) to Shimano OR Mountain bike pedals (in which case there are less expensive conversion kits). Otherwise, if you've received the updated battery door you're good to go!

Garmin Rally Upgrades
----LONG VERSION ----

If you’re like us, you want to keep up with the latest in cycling dynamics. Therefore, you’ll want to know that Garmin’s not just dropping a new power meter pedal … The titan of technology has created a whole family of them.

So how do the Garmin Rally power meters measure up to their predecessor, the Vector 3/3S power meter pedals? Let’s just say, not only did they improve on the Vector, they expanded into a whole range of cycling power meter options.

The Vector power meter took measuring your cycling output to a new level of accuracy with sensors housed right in the pedal. But it was not without its design hiccups. That’s why we’re excited to share what we’ve learned about Garmin’s Rally Family lineup (RK200/100, RS200/100, XC200/100) of bike power meters.

Read on to find out how you can ride on with this latest line of power meter upgrades.

The Vector 3/3S — Room for Improvement

The Vector bicycle power meter brought the next-level technology that Garmin is known for: easily transferred pedals, single- and dual-sensing options, seamless product and software compatibility, superior battery life, and more.

However, ongoing issues with the battery door and contacts somewhat defeated the purpose of the accurate measurement of power and cycling dynamics these power meters were meant for.

Cyclists of all walks of life were experiencing intermittent connections, power dropouts, and missing sensors. Understandably, this caused frustration for riders who were looking for that training edge and wanted to measure the results of pushing themselves on rides.

The Rally Family of power meters is Garmin’s long-awaited answer to the design flaws of the Vector models. They’re loaded with upgrades and tested to the extreme, so you can push them—and yourself.


The Rally Power Meter Nomenclature

The Rally models are described with letters and numbers that tell you a good deal about that particular power meter.

The first two letters of the model designate the cleat interface (RK for LOOK KEO, RS for SHIMANO SPD-SL and XC for SHIMANO SPD).

The numbers that follow indicate whether the pedals provide dual-sensing or single-sensing power measurement (100 for single-sensing, 200 for dual-sensing).


Rally RK200/RK100 — The Vector 3/3S Perfected

Technically speaking, the Rally RK200 is closely related to the Vector 3 but with important updates to design and software.

Say goodbye to the flawed design around the battery in the Vector 3/3S. A metal cap has replaced the Vector’s plastic battery door. And the battery contacts have been updated as well.

As expected, this new generation of Garmin cycling power meters is upgraded with the latest software. Furthermore, this next level in power meters has been rigorously tested.  

The dual-sensing RK200 measures total power, cadence, left/right balance and where in the pedal stroke you’re applying power to help you ride more efficiently. Like the Vector 3, it is compatible with your favorite LOOK KEO cleats.

Check out the Rally RK100 for single-sensing of total power and cadence. It’s an affordable way to start with the option to upgrade to the dual-sensing system. In the fashion of the Vector 3S, it’s compatible with your favorite LOOK KEO cleats as well.

Additionally, the transferable spindle allows you to keep riding year-round — from road to gravel to cyclocross and much more. It can be installed in the Rally RS/Rally RK road pedal body kits (each sold separately).


Rally RS200/RS100 — SHIMANO Platform Passion

If you like to pair your favorite SHIMANO SPD-SL cleats with your cycling passion, Garmin has upgraded and tested these power meter options to the extreme, specifically for you.

The dual-sensing Rally RS200 measures total power, cadence, left/right balance, and where in the pedal stroke you’re applying power to help you ride more efficiently.

If it’s simply total power and cadence you’re after, check out the Rally RS100 single-sensing power meter. It’s an affordable way to start with the option to upgrade to the dual-sensing system.

Additionally, the transferable spindle allows you to keep riding year-round — from road to gravel to cyclocross and much more. It can be installed in the Rally RS/Rally RK road pedal body kits (each sold separately).


Rally XC200/XC100 — Mountain Bike Power Meters

Specially designed for off-road riders. The Rally XC is Garmin’s new power meter platform dedicated to mountain biking and gravel rides.

These power meter pedals are compatible with your favorite SHIMANO SPD cleats.

The dual-sensing Rally XC200 measures total power, cadence, left/right balance and where in the pedal stroke you’re applying power to help you ride more efficiently.

Keep it simple with single-sensing of total power and cadence with the Rally XC100. It’s an affordable way to start with the option to upgrade to the dual-sensing system.

Additionally, the transferable spindle allows you to keep riding year-round — from road to gravel to cyclocross and much more. It can be installed in the Rally RS/Rally RK road pedal body kits (each sold separately).


We’re Team Rally

Garmin’s rigorously tested updates in design, software, and options make the Rally power meters the obvious choice for cyclists who want the most accurate measurement in power and cycling dynamics. All that’s left is to decide which model fits your passion and purpose:

  • Rally RK200 Dual-Sensing Power Meter — You’re a fan of the LOOK KEO cleats and all the cycling dynamics dual-sensing offers.

  • Rally RK100 Single-Sensing Power Meter — You want to measure power and cadence with the option to upgrade. And you love your LOOK KEO cleats.

  • Rally RS200 Dual-sensing Power Meter — You prefer the SHIMANO platform and to push yourself with cycling dynamics results.

  • Rally RS100 Single-sensing Power Meter — You just need your SHIMANO SPD-SL cleats and to know your power and cadence.
     
  • Rally XC200 Dual-sensing Power Meter — You’re SHIMANO platform and off-road all the way. And you want all the cycling dynamics a power meter can offer.

  • Rally XC100 Single-sensing Power Meter — You keep it simple with power and cadence measurements and your favorite SHIMANO SPD cleats.
