If you are a seasoned bike owner and you're used to doing maintenance on your bike, then maybe you would need this. I'm new and this makes things SO MUCH EASIER. I have a direct drive indoor trainer so I need to remove my rear wheel and it keeps the chain out of the way and my hands grease free so I can remove the wheel and get it aligned with the trainer. I'm not fighting lining everything up and it's so easy I don't mind going back and forth... It's easy to ride inside once day and outside another. Plus, it keeps my hands grease free so I can just start riding without getting grease on my bars. I would suggest putting it on the smallest gear and just follow along with the instructions the first few times and you'll be good to go!
