Is it tricky or difficult for a non-technical person?** A: It's easier, actually, than putting on your rear wheel. Just get the chain in the roller wheel of the device, slide it into the rear chain stay dropout, then lock the quick release lever. If you want more or less tension in the chain you can simply adjust your rear derailleur to lower or higher gear and rotate the crank. **Q: i have one. no need if you have a thru axle. simply use an old adhesive bandage spool and your thru axle. I use mine mostly for transport** A: That would definitely work too! **Q: Is there a bearing in the contraption, or does the plastic wheel just spin on the axle?** A: No bearing; although, otherwise well made. The plastic wheel spins on a metal axle. The chain rides on the plastic wheel which is free to move sideways when shifting gears. This makes it easier to clean the derailleur linkages as well as the chain. **Q: Will it work on my 6KU track bike?** A: Probably. It's designed to work with quick release axles. Your bike as bolt on axles. It will not work with thru axles. It is adjustable for the thickness of the drop out. If you still have the factory bolt on axles , you'd have to undo the bolts with a wrench, remove the rear wheel and then use this hub. To put the wheel back on, you'd do the reverse. If you're not familiar with the terms "quick release axle", "bolt on axle", "bicycle drop out" a quick search of Youtube should help. You could also show take your bike to a local bike shop, show them a pic of this item and ask them if it would work. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Tool for Bike Cleaning *by on Reviewed in the United States January 11, 2023* I have no idea what to do when it comes to fixing a bike. I was told to buy this tool to make it easier to repair or even clean the bike, I knew I had to try it out. It makes my life soo much easier, instead of having to clean the chain or the bike while it was dangling, all I would have to do is put the tool onto the bike and the chain is no longer dangling. I have no idea what the names are for the different parts of the bikes, but this tool works like it is supposed to and I highly recommend this item. I would definitely buy it again. ### ⭐⭐⭐⭐⭐ Effective for chain cleaning *by on Reviewed in the United States January 23, 2019* Only takes a few seconds to install. Very well made and amazingly simple. Makes cleaning your chain much easier, and much more effective. Once you get the rear tire out of the way, it's so much easier getting all of the components clean, particularly your brakes. Cleaning the chain is a snap. My favorite aspect is being able to lube the chain without having the extra lube all over your rear cassette. Much easier keeping your rear cassette consistently clean this way. This product is well worth the investment. ### ⭐⭐⭐⭐⭐ Why did I not buy this sooner? May'be I'm the 'dummy'? *by on Reviewed in the United States June 25, 2016* I've had a 'dummy hub' on my bike wish list for months but wasn't sure I'd use it. I ride regularly, and have an unexceptional 4 door sedan. Instead of using a rack I take the wheels off and put it in the trunk (I've done it hundreds of times and and almost do with my eyes closed). Without this device, the chain would go 'loose' and usully come off of the small ring and get stuck between the small ring and the frame. It wouldn't damage the frame, but it was just a nuisance.With the dummy hub, it keeps enough tension on the chain (without the wheel in place) so that I can place it in the trunk and the chain stays in place. Will also be useful for chain cleaning when the wheel removed.With the bike in a workstand, you can also pedal and shift the bike with this in place.Now, my road bike has either a wheel or this dummy hub installed at all times. No more loose chain! ## Frequently Bought Together - Park Tool DH-1 Dummy Hub - Park Tool BCB-4 Bike Cleaning Brush Set - Park Tool CG-2.4 - Chaingang Cleaning System,Blue --- ## 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.lk/products/9096024-park-tool-dh-1-dummy-hub-park-tool-dh-1](https://www.desertcart.lk/products/9096024-park-tool-dh-1-dummy-hub-park-tool-dh-1) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-08-31*
