The standard wheel hoop reducers are the same concept as the original, but with a recent facelift and the addition of reusable zip ties, allowing the zip ties to stay with the hoop reducer the whole time meaning it’s always ready to go and with less chance of losing parts. You can add or remove the hoop reducers in seconds, allowing any configuration of bike fitting on the fly time and time again, and the re-usable zip ties eliminate the need for single-use plastics. Please note: This product is sold as a pair.
