How to: Convert Vector 3 to Rally SPD-SL/SPD Pedals!

Probably the best (only?) kept secret of Garmin’s just announced Rally pedals is the fact that you can actually convert any Vector 3 set to either Shimano SPD or SPD-SL pedals. So if you’ve always wanted a Shimano SPD-SL (road) or SPD (typically off-road) pedal based power meter, you’re in luck. The process takes about 3-5 minutes for a set, and is silly easy to do. This is because inside every Rally or Vector 3 pedal set are two key things: The spindle, and the pedal body. The spindle is where the magic happens, and what measures your power. Whereas the pedal body is what you clip into and visually see. Up till this point, Garmin has only offered LOOK KEO pedal bodies for Vector 3 (save a quirky Vector 1 SPD-SL cartridge thing years ago, that Tinder date didn’t last). But with Rally, Garmin has basically added two more pedal body types, and you’re able to fully convert between them as you see fit. Note – this is a 100% fully supported, designed, and purpose-built process. This isn’t a hack. Garmin specifically wants people to do this (and markets/promotes it), and specifically ensured compatibility between them. Now in effect Rally is basically Garmin Vector 4. Except unlike the jump from Vector 2 to Vector 3, almost all the changes here are in the pedal body & battery compartment (and any Vector 3 user can get the most recent battery compartments for free). In order to quickly explain the naming convention Garmin uses, here’s a quick refresher on the three variants of Rally pedals/bodies: Rally RS: Shimano SPD-SL Road variant (get it? RS = Rally Shimano) Rally RK: Look KEO variant (RK = Rally KEO) Rally XC: Shimano SPD MTB Variant (XC = Cross Country)
