| 17/6/2016 6:37 PM JetBlack Rollers R1 Aluminium at an affordable price by Jacky - verified purchaser I'm very happy I bought the rollers. It's the first time I have ever used rollers. It's a bit tricky to stay on at first but after a few goes it became easy. It helps me a lot with my training when it's raining and can't go out for a ride. I would recommend this product to all cycling enthusiasts out there.
