A disc brake is the perfect choice for people who are looking to upgrade their brakes for an older model bike without increasing costs and disrupting the bike's overall performance. A disc brake is a brake that fits directly onto the disk of your drive-train, instead of the pads that are fitted to your rotors. This gives you the benefit of instant brake response, but also means that your brakes can now work as hard as the other components of your bike. Disk brakes are especially great if you are looking to upgrade your braking system without having to alter the other parts of your system, as you will still be able to use your brakes if you need them. You can also have it custom-made to suit your specific needs. If you are looking for retrofitting your brakes to work with your retrofitting kit, there are a few things that you need to know first. Since all the components that make up your bike have been manufactured specifically for the year that you drive it, you will need to identify which models of braking systems are compatible. In most cases, the disks that you can get today are made to fit the original models of bikes from the 70s, so you should have no problem with these. You will also need to make sure that the size of the disk that you get is the right size to fit on your bike. There are many suppliers out there that specialize in this, so make sure that you choose one that has experience in this. Getting a disk brake for Retrospec bikes is a fantastic way to instantly give your bike a little bit more stopping power. Not only will it give you better stopping power, but it will make your bike look really cool and give you a lot more confidence when you are out on your bike. This is definitely a very good choice for people who want to update their bike.
