Park Tool DH-1 Dummy Hub Tool, blackone, Black

As they say, 'you get what you pay for', or at least you hope you do and in this case they are spot on. Yes it does cost considerably more than most of the other tools of this type but it performs faultlessly and the build quality is excellent. The quick release is better quality than the ones on the wheels and they're not cheap wheels! Not sure if it fits 'Through Bolt' axles, but it works well on my road bike and my hard tail XC trail bike. Well done Park Tools.

Fits into the drive side rear dropout and clamps using a QR lever. So easy to work on your chain without the wheel. Quality is excellent and of course, it comes in Park Tool Blue! Quick delivery, great service....

Brilliant little device to keep the transmission turning with the wheel off. cleaning chain especially is much easier. Works for both QR and thru axle (you just attach it slightly differently).

I don't know how I managed without this when cleaning my bike! It allows you to remove the rear wheel so you can thoroughly clean the chainstays, seatstays, seattube, rear derailier. Then clean the jockey wheels without the wheel being in the way. Simple and very effective. The only negative is that it is a bit overpriced for what it is. The parktool is the best option if you have QR and Thru-Axle bikes.

Great bit of kit to either transfer your bike in the back of your car having to take your wheels off and keeping your cain off the frame or cleaning your chain with ease

A brilliant product to help me clean my road bike with the rear wheel off. It holds the chain securely and lets me give it a good clean. Great value for a great product.

Bit pricey for what it is but very well made. Wish I had got one years ago. So simple to use can do all cleaning and maintaining without the wheel in the way.

Works well. I have thru axels, and at first it wasn't obvious how this would work. It seems that you can dismantle it and thread your existing axel through the plastic wheel. Though I'm sure if you want to do it this way there must be cheaper alternatives. For me, I unscrewed the black plastic cap on the end of the short axel provided, pushed this axel through the receiving socket of my frame, then screwed the cap back on again. So, is a bit easier. Saying that, for those with only thru axels I would suggest saving some money and seeking out a dummy hub which is no more than the black wheel.

Lo use para una cadena de 1 paso, queda algo salida pero al girar se ajusta bien, la use también en una KMC K1 y funciona muy bien, facilita mucho el mantenimiento de la cadena, sin duda lo recomiendo

Eccezionale,essenziale per la manutenzione!!!!

It's simple and effective, and does exactly what it's supposed to do. It greatly aids in cleaning chains and I am very happy with it.

Ich habe mittlerweile 5Stück, für jedes Rad einenTransportkettenspanner, so kann die Kurbel beim Verladen in Position gebracht werden. Kaufempfehlung!

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.
