Using this Brompton chain tensioner assembly is easy. Just install it on your Brompton bike that has a single rear sprocket and no derailleur. When you're riding, it'll keep the chain tight, giving you a smooth ride. When parking or folding the bike, it'll still do its job of maintaining chain tension. Here are some things to note. Make sure to check that the part code QCTADR and part number 9023004 match your bike's requirements. For maintenance, regularly clean the chain tensioner to remove dirt and debris. You can use a mild cleaner and a soft cloth. If you notice any signs of wear or if the chain isn't staying as tight as it should, it might be time to replace the tensioner.
