Shifter worries
So here you are 15 miles away from home, on a trail nowhere near any roadways on your gravel bike and your brifters crap out. How do you make field adjustments to lock them up to stay at least in a low gear so you can pedal back home ? That is my fear with the Shimano 10 speed
brake shifters. I had Shimano bar end shifters mounted up on the handlebar with Paul Thunbie mounts earlier and with them I could switch to friction shifting if the indexing crapped out, which was nice, but now I am spoiled with the Shimano brifters. |
You're overthinking this massively. Replace the cables/housing once a year like you'd change the oil in your car...it's preventative maintenance. If you're that worried about it carry a spare cable with you and maybe some needle nose pliers. If you think you can get home in one gear put the cable in the derailleur backwards so the head is in the barrel adjuster. Push the derailleur into a gear you can ride and tighten the anchor bolt.
As happens all the time this should've been posted in 'bicycle mechanics' not GD but I wouldn't have seen it as I'm still banned from that section. |
thanks cxwrench, the cable technique sounds good. I will check it out.
Yeah, I'm sure I'm overthinking it :lol: |

OP: cxwrench is spot-on. But if you still get stuck, just ride home or call a friend for a ride. No biggie. It is marginally easier if you ride a 2x, as you can shift the other derailleur. |

If it's a front derailleur cable there's nothing to worry about, as it'll simply drop you into the small chainring and you can ride home in a tiny gear. You'll be able to climb fine and spinning out downhill won't matter really.
If it's the rear derailleur cable, like above has said try jamming something from the roadside into the rear derailleur to "push" it into a good gear, or pull the cable tight so it "holds" in a middle gear then tie it off to the frame ir a mounting bolt or whatever is in reach of the cable. Not pretty, but it'll get you home. Worst case scenario is that you're stuck in the small front / small rear combination. You'll likely still be able to pedal yourself home. It's not a huge concern though. Times I've had a cable snap in tens of thousands of miles: 2 (both could have been prevented with a little more maintenance)

the limit screw will get you at least one if not two gears up from the hardest.

I love single speeds and fixed gears, I have two of them and have plans for the third but that isn't so much relevant in this thread. We are all pretty understanding that generally yes a single speed or fixed gear is lower trouble and no shift issues however if you have a shifter probably listen to what cxwrench said it is good advice. Keep things well maintained and you are less likely to have an issue and if you get totally screwed out there just Missy Elliot it: Also get really top quality cables and housing and that can help as well along with maintenance. If you have severe bends a more flexible set up like say Jagwire Elite Link might be helpful to provide a smoother cable transition and with the really high polished slick stainless cables it makes them glide so smooth. |

Carry some thing that you can cut the cable with where it runs bare along the downtube. Then you can tie it off on a bottle cage or some where else convenient in the gear that you want.

Then why not wedge something between the end of the limit screw and the point it hits to get a bit more if needed? If you were that worried about it you could make a little cable end with a set screw that could be adjusted to roughly the right gear and fine tuned with the barrel adjuster. Given how unlikely you are to need it and how many other work arounds there are I wouldn't bother. |

Carrying a spare thumbshifter sounds like a good option Miele Man.

You're kidding, right? You're more likely to break a chain, you going to carry a spare one of those too?

How often do brifters just "crap out?" Twist shifters on cheap Walmart bikes, yeah, I've seen those crap out and not keep friction or hold their position, but brifters and trigger type shifters are a different matter.

Gripshifters aren’t all that delicate either. I see a lot of them at my local co-op. They are simple and robust. I’ve seen broken ones but that’s the result of a crash or someone trying to remove them without knowing how. |

Carrying a thumbshifter sounds ludicrous. I'm pretty sure those cheap ones don't split so you have to unwrap the bartape, pull the 'brifter' off of the handlebar, install the thumbshifter, brifter, and re-tape that half of the bar. |

I had one get bad enough to be shifting badly on tour, but not close to actually breaking. I stopped in the next town with a bike shop and bought a cable. I could imagine someone not figuring out what was going on and possibly breaking the cable. Carrying a spare cable would be the answer for that though. |
