Hi to all...
So, in next few days i will change frame and fork on my road bike from 6061 to carbon :) Everything is ok but i need help from you guys on one thing. I'm little confused do i need a new cables (and housings) for new frame? I'm asking because on my new frame every cable guide is slightly (approx for 1cm) left or right than on my old frame (route is the same). Will this 1cm different to left-right pre-stretch my cables ? Do i need new cable set or i can just put the old one...
equipment on bike is shimano 105 from last year
thnx to all

I don't think you will know for sure until you try them on the new frame.

Dura-Ace cables are $15 a set from Jenson. If you are spending the time & money to build a new bike, don't you think its worth it to buy new cables?

Sure do, good thinking! I will make it so :)
Will dura ace or ultegra cables fit my shimano 105 (5600) levers? I'm asking because of all that tiny cable ends and ferrels?

You won't know until you start to fit them. New housings probably. Make it the last thing you do to the bike.
If you get new housings then new cables for the shifters might smooth things out if the old ones are, er old. For the brakes, there may be no noticable improvement. You'll need some method of cutting the outers, and a bunch of those wee end crimps. Cable stretch for both inners and outers isn't really an issue once they have bedded in.
New cables and housings are not overly expensive as wheelgrabber points out. Shimano make brake and gear cable kits for about the price of a bottle of Scotch. If you hit any problems fitting the old ones, pop on a new set.
Any cable fits anywhere.
Reusing old cables will get you into all sorts of time-wasting gymnastics to end up with a botched-up job - 90% chance you'll have at least one cable that'll end up too short.

You may loose the ability to turn the bars all the way without your cables limiting you. Either way, if you're doing a frame up build, why not invest a couple bucks to replace all your cables and housings. Your shifting will thank you later

for a new I certainly would use new housing. hopefully I could get some colored stuff to match the decals on the frame. however I still skimp on the cables and almost always reuse the old rear cables for the front on the new frame or repair. that saves one inner cable for a replacement.
