Was going to pay $38 from unicycle.com when I was checking out, shipping was going to be another 20 bucks. That got me looking at other options. These work great! Much cheaper. East to put in and adjust. A win win win (unless you’re Unicycle.com.). ## Frequently Bought Together - SE BIKES SE Chain Tensioner - SE BIKES Bear Trap - SE Racing Champ Clamp Seat Clamp 31.8 Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/72533851-se-bikes-se-chain-tensioner](https://www.desertcart.be/products/72533851-se-bikes-se-chain-tensioner) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-10*
