Do you ever find yourself with a burning question you’d like to directly ask a cycling coach? Well, now is your chance to ask away! In this series, we’ll be putting your questions to expert coaches – send them in to Cycling Weekly's Fitness Features Editor at anna.abram@futurenet.com

ERG mode is a mode on your smart trainer whereby the trainer dictates the power you ride at. It will automatically adjust for the cycling cadence you are using at and so there is absolutely no shirking when riding in ERG mode.
