Like all JetBlack trainers the R1 aluminium rollers are pre-assembled and ready to ride. They contain sealed bearings for a smooth and quiet ride. Their low profile means that when folded, they don’t take up much storage room. With winter approaching, rollers give you an alternative to stationary trainers. They will improve your handling and your pedalling efficiency. They also don’t need your bike to be clamped in, simply place them on the floor and start riding.
Price: $259
