Saris H3 Smart Trainer
The Saris H3 Smart Trainer from Saris is perfect for use with indoor training applications like Zwift or TrainerRoad, as it can measure power of up to 2000 watts with an accuracy of +/- 2%. As a direct drive unit, there is no tyre wear to worry about and as the resistance doesn’t rely on friction between rubber and roller there is no possibility of it slipping during hard efforts.
The trainer has super wide legs for great stability, but they can be quickly folded away for storage when not in use, and it has an integral handle for carrying. All common frame standards can be used with the trainer; 130mm and 135mm quick release and 142mm and 148mm thru-axle. Integrated dual ANT+ FE-C and Bluetooth FTMS standards are included for easy connectivity and firmware updates can be done wirelessly via the Saris app.
