handlebars with dual grooves... while cables goes where?(8 posts)

handlebars with dual grooves... while cables goes where?gnailuh

I had a one groove bar, with campy chorus. now i have a deda bar with two grooves. one groove inside the curve and one outside... is the groove inside the curve for the shifter and the outside one for the breakes? or vise versa?

when i say inside the curve, I mean the groove in front if you're seated on the bike.

brakes in front, gears behind.

this is from my lbs, a pro mechanic, and myself.

brake cables on front groove, deraileur cables on rear.

have fun

How do you get the der. cable shrouds to cross each other in front of the steerer from the back grooves - or what kind of crossing pattern did you work ? Facing the bike, how do the shrouds look, that is. Just curious, I haven't used the back groove.
Done right, the back routing looks cleaner...seyboro

Try this: (looking from in front of the bike at the headtube)
1. route the front brake cable/housing first so it looks to run parallel to the headtube.
2. route the rear brake into the top tube cable stop so that it intersects the front brake cable at the center point of the stem or headtube.
3. route the front derailleur cable from right to left (looking at the headtube)across the headtube back into the front derailleur cable stop on the downtube. Cut the housing so it crosses the brake cables in the same spot.
4. same process, reverse directions for rear derailleur cable.
Do you have a picture to share?gnailuh

seyboro, can you post a picture of how you did it? or can you email it to me at thanks!

Sorry, without a digital camera, pictures are beyond my capabilities. However, if you get any magazines (cyclesport/procycling/velonews), look for any frontal shot of Museeuw's bike or any Domo bike, for that matter. Clean, well done cable routing.
Any Coast bike will show you the difference as they run theirs in the front and their mechanics seem a little sloppy to boot.
With a good picture and the above directions, you will be able to do the job. To me, the keys are:
- the front brake housing runs parallel to the headtube, almost vertically into the caliper
- all 4 cables cross at the same point under the center of the stem
- both shifter housings have the exact same length
Good Luck and let me know how things worked out!!
route both up front....C-40

Campy ergo levers always route the brake cable in the front, but the derailleur cable may be routed either in the front along with the brake cable or by itself along the back.

I prefer to route both cables along the front, even if the bars have no grooves, like Easton EC-90 carbon bars.

Yes, I route everything [campy] up front, too.
