When to change internal cables?

    Externally routed cable – no problem, a few quid, 20 minutes, job done. Internally routed cables? PITA, but a bigger PITA if they snap.  My good bike rarely gets wet, and has just crossed the 5,000 mile mark. When should the inners be replaced, and I guess equally important, what about the outer sheath?

    Nope…. still get the 58/6800 in for snapped off at the nipple….  many are found early (as I take a look now) and some are found with just a few strands left connecting the cable to the nipple….. 


    Mine is a 2016 bike with 6800. Broke at the shifter.

    The new STI’s seem pretty bad
    The new STI’s seem pretty bad for wrecking cables (5800 6800 r7000 and r8000) I’d recommend changing inner gear cables every 3k miles.

    I had two snap both around 3k miles.

    I once suffered the misfortune of puncturing front and back (tubulars) simultaneously at the end of a 120km ride – but right in front of my favourite café.

    Mind you, a cortado and biscotti did nothing to take the sting out of the fact that they were silk-lined FMBs.

    Griff500, what everyone will want to know is: where exactly was the break?

    Half a k South of Simiane la Rotonde.

    Nice evasion. (Not the town, the question!)

    Haute Provence eh?  Some riders have all the luck!

    Hubris?

    You cross chained all the way home? Any true English gentleman of breeding would have left it in the big ring and risen to the challenge, willing to sacrifice cartiledge and sinew to do the right thing.


    Afraid not. I used the big ring to get me to the nearest cafe, then phoned mission control to send a rescue shuttle.

    Honour restored.

    I changed all the internal cables on my Giant recently. This led to the best bit of advice I could give anybody about cable inners if you’re fitting new brifters. DON’T use the Shimano inners they come with, the inners that have that weird flakey coating. When you eventually come to remove them, this coating sheds and completely bungs up all the tiny holes you need to get inners in and out of. Bin them and use bog standard stainless inners instead.

    That sounds like the cable end came off in the shifter.

    I always advise customers on

    I always advise customers on 105/Ultegra to swap out cables annually (obvs I know who put the miles in) to save the Shifter snap issue… always these 2 japanses shifters… 

    As for internal cables…. apart from the above caveat, it’s bike dependent… a certain manufacturer/online retailer in Sheffield has some routing issues under the Bottom Bracket to derailleurs but I only see it as I have the bikes stripped out… most only need new cables when the old ones (if galvanised) break out and drag inside the housing (common on some of the so called “brands”) …other than that…. it’s owners preference or what is seen at service and customer advised before replacing
