Mountain Bike Won T Shift Gear

Gears won t shift up or down perfectly with one click solution.

Mountain bike won t shift gear. Gear cables will stretch. As the 1x drivetrain becomes standard issue on capable cross country trail and enduro bikes we re left with one shifter cable and derailleur to adjust for top to bottom gear range performance. The second video in this. I am often asked how to fix a bike that won t shift gears or will only shift to some gears.

I don t think this is a huge deal because 1st in front 5th in rear is a plenty low enough gear to get started climb the kind of hills i ll be climbing anytime soon. The global mountain bike network is the best mtb youtube channel with videos for everyone who loves dirt. Assuming its a high normal rear derailleur shift it to the highest gear turn both barrel adjusters the one at the derailleur and the one at the shifter all the way in but for a couple of clicks. They ll stretch the most when they re new.

Derailleur and gear cable problems cable stretch. I set it all up and when i got on the bike and started shifting the bike shifting in the back to the largest cog so lowest gear but now i am unable to make it shift at all to a higher gear. The rear derailleur is the heart of most mountain bike drivetrains. Turn the b screw clockwise to make the gap larger and counterclockwise to close the gap.

Stop shifting when you find an issue but keep your bike in that gear. But i thought i d mention it anyway. The problem will be the shifters derailleurs or cables. I can go between 5th 6th and 7th gears but trying to go any lower than 5 won t work as there s just too much resistance from the shifter.

This is most commonly caused by stretched gear cables and you will need to re index your gears. If it used to shift into low gear and now it doesn t what has probably happened is the cable housings have seated in and the cable is loose. I bought a bike trainer over the weekend and so i wanted to throw that bike on the trainer and use it for indoor use. I walk through the steps to isolate and locate.

Derailleurs can be used to loosen and tighten cables but also to align the chain. On modern mountain bike shifters barrel adjusters are mounted on the shifter right where the cable housing exits the shifter body. Shift to your problem gear while pedaling the bike with one hand shift your gears up until you get to a problem such as if the chain won t shift has trouble staying on the gear or skips a gear.
