how do i adjust the rear shimano 105 derailleur?

Answer 1

Don't mess with the adjustment screws, instead use the barrel adjuster (a black knob at the end of the cable near where the cable goes into the derailer. If the problem is shifting to lower gears, which is the most common, turn the barrel adjuster towards the spokes 1/2 turn at a time. After the turn check how shifting is by going through a number of gears. If needed turn a half turn again and repeat. If the derailler sustained a hit, take your bike in to your lbs.

Answer 2

at the beginning, you may no longer use all a threat combos. The extremes, it is the smallest sprockets in back with the small chainring in front and the main important sprockets in back jointly with the vast chainring in front won't artwork nicely and could reason intense positioned on of all aspects. A medium cage derailleur will artwork best for you, yet you will no longer see any progression in shifting. Sora derailleurs are rather good high quality, they shift nicely. as a replace of upgrading your derailleur, purchase a collection of Tiagra shifters, they are plenty greater helpful than Sora shifters, and could easily strengthen the shifting on your motorbike. they're going to fee better than a derailleur, yet will make plenty greater of a distinction.
