Adjust a Mountain Bike Front Derailleur

Video Transcript

"So after you have your front derailed installed or maybe you already have a front derailed installed on your bike and you can't figure out what the adjustments do and how to affect things, hopefully I can help out. So what you have on your front derailed just like on your rear derailed. The things that are important are a that its installed correctly. If you are confused about how to install it correctly you can go back and video but the adjustments are the same as they are on the real derailed. They are limit screws, one of these is for the inside limit, one of these is for the outside limit, then your cable tension. So adjusting your cable tension is the first place to start. The first adjustment is you want to shift your bike into lowest gear, so on this type of shifter you hit the small thumb paddle to shift down. You can see when I hit that I go down. And what you do is with minimal cable tension, I'd say no cable tension, just undo the cable stop all together you want to set the limit screw so that with your crank set on, I've removed the crank set for demonstration purposes here, but with your crank set on you want everything to basically line up so that your cage is just clearing your small chain ring. So if my wrench here is the derailed cage you want to set up a gap about that much. What that ensures is when you down shift by hitting your shift paddle you'll shift down no matter what. It will remove, the cable tension will come off the derailed and it will come down as far as it needs to go and no farther. Your chain won't derail off the inside of the chain ring which is of course an unpleasant occurrence."
