View Full Version : about disc brakes at the rear

04-08-2006, 11:40 AM
Is there some way or some part from any manufacturer that you can use to attach disc brakes to the rear end of an old bike that doesn't have the (not sure about the word here) flaps at the back where they're usually attached to? I don't know the word for the part that's missing from my friends bike so it's kind of hard to search from the web and from this forum as well:( I've asked from all my local shops (Finnish) but none seems to know.

Any help here would be appreciated, we've been trying to figure this one out for a long while now.

Ps.. my friends bike is Marin palisades trail

Although it probably isn't a good choice, it is indeed possible. First you will have to have a new rear wheel built... one that actually has a disk hub so that the rotor can attach to it. There is an attachement that bolts onto the frame to hole the brake caliper as well... can't seem to remember the name brand as this time. Good luck!

There are ways to do this, but they aren't cheap. Hope this lets you get to 2 of the options. http://myweb.search.yahoo.com/myresults/myresults?fr=myweb&.done=http%3A%2F%2Fmyweb.search.yahoo.com%2Fmyweb&fid=181. There is a cheaper option on eBay. I'll try to find it again. http://sporting-goods.search.ebay.com/disc-brake-adapter_Mountain-Bikes-Parts_W0QQbsZSearchQQcatrefZC6QQcoactionZcompareQQcoentrypageZsearchQQcopagenumZ1QQfgtpZQQfposZQ5AIPQ2fPostalQQfromZR2QQfsooZ2QQfsopZ2QQftrtZ1QQftrvZ1QQlopgZQQsacatZ22678QQsadisZ200QQsaprchiZQQsaprcloZQQsargnZQ2d1QQsaslcZ2QQsbrftogZ1QQsofocusZbs I'm not sure I would go the cheap route. My concerns are that if the bike frame was not designed for disc brakes, these could put an awful lot of stress on the seat stay at a point that it might not be able to handle it. I would talk seriously with an experienced bike mechanic that has had a chance to look at your frame before going that way. The Therapy and Woodman adapters get around that concern, but at such a cost that unless you can't find a frame to fit you that has disc brakes, it would be cheaper to buy a new frame rather than build new wheel and buy those adapters.

Thank you very much for you advice. My friend now ordered a set from ebay and is really looking forward to installing it.

Thanks :D

edit: I'll try and post a picture of it after he has installed the set on his bike!

Picture is a bit large but this is the way he finally did it with the part he bought from ebay :D
so thanks again for the hint..

Wow I have never seen anything like this before. There sure is a lot going on there.

By the way looking at your picture you are in need of some new jockey wheels and that chain sure needs a good clean.
