Brakes for tandem

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

Cannondale has put Avid ball bearing disk brakes on their 2004 Road
tandem. Does anybody know these brakes ? How good are they ? Is this a
good idea to put them on a (road) tandem ? Do they represent a significant
advantage over the Avid shorty cantilevers that Trek puts on their tandems ?

Thanks for any input.

I have well over thirty thousand miles on my Hayes Disks on my recumbent
single bike. I have ordered disks on our 'bent tandem, now being built. I
think that there advantages in disks over any rim brake.

I hope they used the 203mm rotor. Excellent.

How does a mechanical disc on a road bike have advantages over a rim brake on a
road bike?

I think on a tandem, discs are a good idea, on a '1/2 bike', single bike,
whether it be a 'bent' or upright, they are a costly, complicated brake.

1. Works even when wet.

B. Doesn't cause rim wear.

I'm less sure they're a good idea for tandems, given current technology.

I don't believe any mechanical discs are "tandem rated" and the greater
stress on spokes could be an issue...tandems already have enough spoke
breakage problems.

If you poke around this link
<http://home.att.net/~thetandemlink/hobbes.html> there is a search
engine specific to tandems and you can find maybe a hundred plus
messages specific to your question. The 203 mm Avid disk is a hot
item to have but no better in stopping the bicycle than a well setup
Canti, Direct pull, or Dual pivot brake.

You will see that it is a very controversial topic.

IMHO the dual pivot with an additional drum brake is the best,
overall braking system for a tandem. The disk brake is not a drag
brake.

I smack rims way before I wear out the sidewall..Only done that once in 20
years of riding.
