Hi all,
Why does Calfee still do full cable guide system on the top tube, isn't this a bit old fashion? Does this require a full housing?? I would figure the weight weary would like to do away with excess housing. Any thoughts???

Most carbon tubed frames do this.I can only think that brake stop stresses are pretty high,and making/mounting a stop strong enough to withstand the forces would actually weigh more than the extra housing.Note that the derailleur stops are on the metal reinforced head tube,and stresses on shifters are low.
In all honesty,this is a WAG:)

You guys are awesome, worrying about the weight of the brake cable housing! I'm very impressed.....

Thanks for the reply. Tipping the scales at 205 pounds and riding with 2 water bottles, bike weight is not on the list of concerns. However, aesthetically, the full guides on the top tube are not too appealing.

they have a functionally benefit: full cable housing ensures that the rear brake housing does not become contaminated, thus making the braking must more smooth. given that the front brake is so short, there is always a difference in feel between the front and rear. full cable housing (though it doesn have more friction), maintains the smoothness of the rear brake for a longer period of time. it is functional. everything about calfees are functional.

...all that asthetically pleasing to me as well. I disagree with "dfcas" who indicated that most carbon tubed frames use full cable guides. I believe that Calfee is in the minority as the majority of carbon frames use the "split cable" method. I imagine that there is a lot of stress, but Calfee did use the split cable system in the past...not sure why it was abandoned unless there were significant frames coming back in for warantee repair or manufacturing was easier with the full cable guide method.

When were split systems used?? Which models? I have a 1995 Tetra and it has full housing (rear brake). The only thing I can think of that may come close to using "braze-on" stops and open cable are the frames with S&S couplers AND then only if they used the quick disconnects from S&S.
