vbrakes / cantilever questions(7 posts)

vbrakes / cantilever questionseflayer2
Nov 23, 2002 3:20 PM
I'm a road biker, but I'm looking at building up a cross frame for a second bike to be used primarily on the road. The used frame I am looking at has cantilever brakes on the rear but I don't think it has a cable bridge on the frame. Without the bridge, should it have vbrakes installed or can you use some sort of adapter to make cantis work? If I'm not asking sane questions, let me know.
There should be a cable stop centered in the rear. ...TFerguson

There should be a cable stop centered in the rear. It may bridge the stays or be attached to the seat tube. I also think that you can get cable stops that attach to the seat tube similar to the ones that attach to a headset.
V-brakes would require Travel Agents, mini-Vs or some other cable pull adapter if you are using road levers.

You're asking all the right questions and the answer is if you don't have a cable bridge on the rear, you "may" need V brakes.

You might get away with a cable stop designed to mount on the seat post binder bolt. They were used on older touring bikes if memory serves. Contact Sheldon at www.harriscyclery.com and find out if he has any, or maybe one designed for your frame. Maybe take a digital photo of the frame and e-mail him a picture to allow him to get what you need. You can also get a front bridge for a 1" threaded headset.

The seatpost binder bolt canti cable stop/hanger should be available at any decent LBS. It's a no-brainer. Check the Harris website to see one, or check out the QBP book. If you're ordering other stuff from Sheldon/Jay, they've got them in stock...different styles and black or silver finish are available...

Costs about 5 bucks...works like a charm.

All those itty bitty bits and pieces that you need to make a useable frankenbike will nickel and dime you to death. Be careful before you buy too. Some seat binder bolts won't accept a hang-on cable stop.

Nice Fuji steel with Ultegra. It came with cantis, but I changed them over to V-brakes using travel agents. I had good intentions to ride on trails when I bought it, but ended up only riding it on the road. Primarily commuting on a paved trail. Off went the knobby tires and on went 700x23's (man do those knobbies slow you down). The brakes never worked as good as regular road brakes. It was kinda heavy too. In the end, I sold it. Wasn't crossing on it and realized that if you want to ride on the road, a road bike is what you should be riding.

Sometimes I regret selling it until I realize that it would be gathering dust in my basement if I didn't.
