How To Adjust A Front Derailleur | Setup & Adjust Bike Gears

The front mech is something that’s been commonplace on mountain bikes for 30 years - though these days it’s more common to see the newer Trail and Enduro MTBs with a single chainring, and more gears at the back. Here at GMBN Tech, we want to support all type of mountain bikers and Mountain Bikes, so making this video was a simple choice. If you have a front derailleur - this is the video you need to set it up to work smoothly 🔧

Does your bike still have a front mech?

Those few of us who still have a front mech appreciate this video.

I don't have a bike with one anymore, but still loved watching this. I think im just addicted to GMBN stuff, i may need to get help.

after 4 hours of tinkering with my derraileur with different videos, this one finally made things clear for me.

[justinbetz]

Spent wayyy too long messing with the gearing tonight. Your video saved me thank you

[johnforster]

Just put a new chain on my daughter's 24" S'cool TroX Elite and now need to tune the front mech. Thanks Doddy and GMBN!

I still use my Trek 8000 from 1989 that has a 3x setup. I needed to adjust my front derailleur and this video made the process very easy.

[Ortoped]

the most useful video ever. Thank you very much. Old bikes rock!

[Mrguitarmaster]

By far the best video on how to adjust gears! Very simple the way you explain it. Thank you for your help!

[davewoodward]

Wow...thank you. On hols in France and took my old bike in case it got stolen off the car. It would not go on the big cog on the front chainset. After watching your great video I manged to fix it (after quite some time of faffing before watching the video) All set for happy holiday cycling thank you so much.

Super-clear explanation, exactly addressing the questions I was having about this task. Many thanks!

[dido]

This video was perfect timing because I had planned to adjust the front derailor. Very helpful.

[vicsimmonds]

Front indexing is a pain in the arse. Nice video 👍🏼

[laurasmith]

Thank you!! my bike wasn't shifting into 2nd gear on the front mech after watching this I figured the wire needed more tension and now it works perfect ☺️

Few months ago bought a brand new bike, i intentionally went for a 2x system, so it has a 2x12. I have no regrets, and probably never will, it's just so easy to ride anywhere.

Excellent instructions. Worked like a charm! Also, my limit screws (for whatever reason) were stripped partway down the bolt, so they would adjust the limits properly. Substitute in a few Allen bolts (M5) instead of the silly Phillips screws and it works perfectly. Thanks for your tips!

[davidparrott]

Like others I don't have a front D anymore. And agreed I just like watching Gmbn informative and done well. And I did get help.. The Doc said to get out on my mtb more.. Result. Keep safe all

[havadatequila]

as a roadie with a front derailleur, I salute you!

[duncanrosie]

Thank you, used your guide to set the front mech on my son’s bike, works like new again, now he can stop angling for an expensive 1x12 groupset😃

[troymouer]

I found this more helpful than the Blue Tool video. Many thx!
