He does a lot of pump tracks with big jumps etc. This tensioner does the job and was not expensive. ### ⭐⭐⭐⭐⭐ Great quality *by T***N on 16 October 2025* Bought after a cheaper off-brand one broke. This feels 10x more sturdy. Strong spring also. ### ⭐⭐⭐⭐ Arrived promptly and in perfect condition. Good price. *by M***E on 12 July 2021* I bought it to allow maintenance of chain tension on a hub geared bike without moving the hub in the dropouts. Seems to work pretty well. It is not ideal for this function because the lateral adjustment is at it’s absolute inmost limit. I think it’s designed to allow a multi sprocketed bike to be used as single speed. For my purposes it would be better if the main arm slanted inwards to naturally align the tensioning jockey wheel with the sprocket of the gear. Despite this I am very happy to use it on my bike and won’t change it unless I discover a better alternative. ## Frequently Bought Together - XLC CR-A03 Kettenspanner - Bike Single Speed Fixie Cassette Conversion Kit Compatable Shimano 18T Colors --- ## 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.pe/products/57221098-xlc-cr-a03-kettenspanner](https://www.desertcart.pe/products/57221098-xlc-cr-a03-kettenspanner) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-04-22*
