What I Need for TTT?

Hi Folks! I can’t seem to find clarification for this anywhere, so I hope somebody here can help. I just joined a TT team, but I don’t have a smart trainer. I use a CyleOps Mag trainer and a Cateye Padrone for cadence and speed readings. I was told that I need a power meter to be able to race and have it count. Do I need to buy a totally new bike computer, or can I buy a power meter and just have Zwift read it? Will the Garmin Bike Speed 2 and Cadence 2 Sensor work? (It was recommended as a possibility) and if so, why wouldn’t my Cateye do the same thing, since it also senses speed and cadence?

Thanks for any help on this.

If you need a power meter then you just need a power meter and you pair it with zwift no need for new bike computer (and no the speed and cadence sensors wouldn’t be an option it you actually need power).

I don’t think I’d put that much money out to be able to join a zwift event myself but a power meter is pretty cool if you can afford it.

I can not confirm or deny that you need one for the event tho. That info should be on the organisers website or something.

Thanks Ben. That was one of the clearest answers I’ve gotten so far. So the power meter is independent from the speed and cadence sensor of a regular bike computer.

Super helpful! I’ll dedicate my first official race to you. :blush:


@Marcia_Blanco if you do need a power source, such as a power meter or smart trainer (not a speed and cadence sensor, or a bike computer like a cateye, they are very different). I think one of the least expensive options are these pedals at $411 https://cycling.favero.com/assioma.
