Internal Cable Routing Fix

    I was a bit careless when replacing a gear cable and the internal cable housing came up into the frame when removing the old cable. I can't thread the new cable out of the bottom bracket opening now. The cable enters the frame at the location shown in the picture at:

    I'm aware that there are internal cable routing kits but the housing is only 3mm diameter and unlike newer bikes (the Rose Xeon CW is 2013) the frame entry and exit points appear to be only marginally wider than the housing.

    Any ideas for getting the cable through ?

    I used a speed sensor magnet attached to a 2mm allen key. Guided the cable slowly down the downtube and used the magnet to tease it out through the cable guide. Your guiding the wire from side to side more than actually trying to pull it through the frame tube. Bike is a Canyon with similar entry point for the cable.

    You tried the thread and hoover trick?

    Got a big magnet of a mate who works in the esb. Some customers use them to slow down the meters but it works very well at picking up cables

    Don't suppose you could make a photo of how you attached the magnet to the key ? A 4mm allen key squeezes into exit, 3mm goes in easily

    Seal any holes in the frame with tape or blue tac etc. saving for the entry and exit points of the cable you are looking to run and use the hoover to suck a fine thread through.You can then attach the cable and pull it through.

    3:40 here and shows some other ways already mentioned here

    Had to do the string and hoover trick recently. I thought it would be a bit more difficult because I had been fiddling around trying to thread the cable by feel and with a magnet with little success. Using the hoover sorted it out in seconds. Ridiculously efficient. Would recommend!

    I don't recall having to close up the other guide holes either, as the thread is so light the vacuum will get it anyway.

    Just seeing this now. As per the video posted, thats exactly how I used the magnet. The allen key inserted into the cable guide looked all sorts of wrong!:D

    I hope you get sorted.

    Hoover worked. Put bike on bike stand and tilted it so that down tube was near vertical. Pulled out hose completely and threaded cable through it. Then fed cable only through down tube with hoover at other end and out it popped. Continued feeding cable while pushing hose back into frame.

    I tried tying thread to the cable but gave up, wasn't needed after all

    Thanks for all the suggestions
