When we saw top athletes training with the PowerTap SL, we thought we had the greatest power meter in the world. But we decided we needed more. In the end, we got less...less wires that is. The PowerTap SL 2.4 is the first wireless power meter on the market. It combines the lightweight reliable SL hub with a 2.4GHz transmission. Hub to handlebar...no strings attached! Now for the MTB rider we have added a disc brake.

With the help of top pros, coaches and scientists, we’ve made PowerTap SL smaller and 160 grams lighter. We’ve also added a new electronics package that’s housed completely within the hub shell. It sends the data through carbon fiber power windows, keeping moisture away from sensitive components.

Wireless 2.4 technology uses more power so you may need to change batteries more frequently
