Morgan BlueChain Keeper - 9mm

This is a good product if you ride fixed wheel, but it is not so good for gears because it doesn't sit close enough to the drop out for the top gear. This means that you have to leave mech in 3rd gear for the chain to sit in the groove.Not the end of the world but a bit of a pain.

Simple, effective, great when cleaning the bike on a stand. Also handy when carrying the bike in the car and you have to take the wheels off.

Arrived on time. As described, no complaints

Great and simple product, it lets you run the chain from the cranks when the wheel has been removed.If you want to degrease your chain you can do it with the wheel on the bike, but then you get degreaser all over your wheel (and your rims). If you take the wheel off to clean the chain you will rub the chain all over the chain stay. This product allows you to run the chain backwards or forwards using the cranks while the wheel is off the bike, saving your wheels and frame from getting covered with crud from your chain. It's a winner!

As a rider of bikes for over 20 years I've seen plenty of items that were gimmicks or tricks, however this little item is not one of them. So simple to use & makes cleaning and bike maintenance so simple to complete.Really fast delivery from the seller and well priced too.Easy to use, just poop out your rear wheel and replace on the driveside and twist the nut to tighten up so that it doesn't pop out. Once in place leaves the chain in tension so you can clean, lube and also do maintence

Easy to use chain keeper. Used on QR and thru axle frames enabling the chain to spin, be thoroughly cleaned etc with the wheel out.

Dead simple idea yet very effective. It is small too, so it easily goes in you toolbox, cheap too.With this you can remove the rear wheel but maintain the tension in the chain. This makes cleaning much simpler, as you have access to both sides of the chain and derailleur. Photos in the pack show how to use it, but don't over tighten it when in position, as it could scratch your paintwork.A really useful tool!

Use this every day, wheels come off the bike and the bike gets stored in a soft bike bag. this makes keeping the chain off the rear stay and consequent damage so easy! Very easy to fit and use and super cheap. Easily the most used and under rated tool in the tool kit!
