Fixing a broken derailleur cable
One of the most tricky things on your bike, the derailleur, its the key-machine in why you’re riding a road/off road race bicycle, to be able to shift gears.
What if the gears don’t shift easily anymore? or what if your cable breaks during training or tour?
I’ll try to give a short explanation on how and why, just enough to get you back on the road in no time at all.
During your rides, the cable may get a little off tension, that way you notice this is because the gears shift a little less fluently and the noise your derailleur makes gets louder. At one moment your gears may shift out of itself when you hit a bump in the road or when you apply a lot of pressure on the pedals. This means you have to tune your derailleur back to its efficient place.
One of the things most bikes have is a tuning wheel on the cable that leads from the gear shifters to the derailleur, with this you can increase or decrease the tension on the cable for a little bit, an increase in tension leads to a shift towards a lighter gear, a decrease shifts towards a heavier gear. Big sprockets are lighter and smaller sprockets are heavier. The only thing is that you’ll get problems with shifting to the out-most gears, so when you change the tension on the cable most of the gears will run smoothly except for the lightest and the heaviest gear.
Below a picture of the derailleur to make the you-tube video a little more comprehensible.
