The Single Speed Conversion Kit is the most efficient and easy way to convert your motorcycle to single speed without buying a new wheel. Review: Forget the rest. This is the best. - I have a surly bridge club frame, and this tensioner fits it like a glove. Seriously, the dropout fits perfectly in. Very straight forward installation. Make sure you have a quick release wheel. Very strong and reliable tension. You will have to adjust it by hand while holding a wrench with the other. I use it for a 500-watt ebike motor. My build is a custom single speed. I tried two other tensioners, and they just broke or felt flimsy. This however is strong. No springs or pulleys. It uses ball bearings that can be replaced. Don't let the desertcart picture fool you. It looks great in person and very nice on your bike. It also comes with the associated bolts to put it on your bike. Review: Easy to install and adjust - I have used several methods to tension chains on single-speed bicycles and they all have problems. This one, though, worked with no issues or fiddly adjustments. There is no spring--you set the tension by pushing it up or down onto the chain and tightening up the bolts. The roller finds its alignment with the chain after a few spins of the cranks. An argument could be made that a spring system adjusts as the chain stretches; however, if that happens it is simple to readjust the tension (5mm Allen key required) and ride on. I image this would only happen once during the life of the chain. I installed it in about 10 minutes and used the rest of my free time to go on a bike ride. If it develops problems, I'll update this review. ## Features - Material: Stainless steel; Weight: 3.6 oz (103 g); Converts traditional vertical dropout frame to single speed bikes.

This is the best. *by G***O on July 17, 2026* I have a surly bridge club frame, and this tensioner fits it like a glove. Seriously, the dropout fits perfectly in. Very straight forward installation. Make sure you have a quick release wheel. Very strong and reliable tension. You will have to adjust it by hand while holding a wrench with the other. I use it for a 500-watt ebike motor.

This one, though, worked with no issues or fiddly adjustments. There is no spring--you set the tension by pushing it up or down onto the chain and tightening up the bolts. The roller finds its alignment with the chain after a few spins of the cranks.

This item seems to be designed for use with a multi speed cassette in the back as the chainline was too far outboard for a single rear cog on the hub. In order to get it to align I had to bend the frame of the item and as such render it beyond return. It is going to be donated to a charity bike repair shop. It is a very well made item and has great looks and I am disappointed I had to learn about not being able to use this ... the hard way. Would I recommend it? Absolutely: it is a quality product but just not made for what I needed. ## Frequently Bought Together - DMR Simple Tension Seeker - CyclingDeal Conversion Kit Fixie Bike Single Speed Compatible with Shimano Sram Cassette Freewheel Hub Adaptor - for Mountain and Road Bike Gear Cog Spacers - Bibike Single Speed Conversion Kit 13T/14T/15T/16T/17T/18T/20T/22T Single Speed Cassette & Spacers --- ## 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.sn/products/4208982-simple-tension-seeker-dmr-sts-chain-tensioner-stainless-steel-drop](https://www.desertcart.sn/products/4208982-simple-tension-seeker-dmr-sts-chain-tensioner-stainless-steel-drop) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-07*
