Wliier Cento Uno rear brake cable - threading through TT

[guylimey]

Wliier Cento Uno rear brake cable - threading through TT - any ideas anyone (the plastic sleeving that was there at manufacture is no longer there and there is no internal tubing in the TT to guide either the casing or just the inner wire)? I have tried cotton thread and a vacuum cleaner, cotton thread with a needle and a magnet and both without success Too frustrated to continue at this point and looking for ideas/help. Thank you.

I can't tell by the picture, but if your putting housing through the top tube, I've had luck running a bare cable through then pushing housing down the cable, pull the cable out, and route your new cable through.

Bare cable, put a kink at the end of the cable. You can spin it from the other end. Once the cable's in place, run the housing over it. Use grease or lube at entry ports

Cable is also steel so you can use a magnet, too! Have fun.

Most cables are stainless steel, so a magnet won't work. Only the cheap zinc coated cables are steel.

Park tool has a video showing their cable routing tools. I saw nothing in it that would be of value for my Colnago frame.

I've been able to use a length of small welding rod, under 1/16", and got it to go through after enough tries.

The key is to never lose the pathway. I use heat shrink tubing to attach a guide cable to the old cable before removing it, to retain the pathway.

Same frame, same problem. The fine thread/vacuum trick worked after a bunch of tries, and I seem to recall capping off other air inlets with my hand/fingers which gave the extra pull on the thread, making the difference. The point is to jostle and manipulate air flow a bit, and that directed the thread out of the suctioning hole. Worth mentioning, the smallest possible vacuum attachment concentrates the suction through the cable housing hole. And of course a punching bag within reach to keep from throwing the frame across the room might be helpful too .

Was it ever there? I bought my 2010 Cento1 used, but the only plastic cable routing line it had was at the chain-stay. That line was effected after a drive-side chain-stay carbon repair job, so I removed it. Talk about a pain! I gave up and the cable is exposed. Works fine, no one besides me knows it's like that.

+1..magnet.

Thanks for all the advice. After a lot or cursing and swearing, 6 aspirins and gallons of tea later I finally got it! Removed the fork to find whole front of frame open so with a needle and thread and stainless steel aircraft lockwire I managed to get a plastic sleeve through the TT and this in turn enabled me to pass the brake with through. Gosh, what a pain in the a--.

I too had the same exact issues with a Wilier Cento. The only more frustrating bike that I ever had to deal with was a Chesini will fully internal cabling. WHY?

Bikes!

Congrats OP, in steel is piece of cake compared with modern carbon bikes.... now remember all the time before putting the cable out to pass a long piece of cable inner casing then remove the cable leavigng the inner casing in place.

May your efforts be rewarded with supreme riding pleasure, Guy pal!

I feel your pain. My wife has a kestrel. It could take hours to route the cable if the Plastic sleeve were taken out or fell out. They are used to route the cable. No internal guides. I bought one of these worth the money.
