I think this is the best explanation on youtube. I'm new to road bike, so this video really enlightens me. thank you! :)
I did not know that this is a feature. I thought my 105 shifter was a 3x shifter and I was confused. This video is exactly what I wanted
I let my dad ride my new Cube Nuroad and he was overwhelmed by this trimming haha. But after a while he got it
As a bicycle mechanic with over 20 years of experience. One of the best thing's that you can do is spend five minutes explaining how the trim work's to a customer, regardless if it's on a new bike or a bike that you have just serviced. It saves you so much time in the long run. Just always remember cables are going to stretch and frames do flex so chain rub is inevitable at times. 👍 cool video
Teach a bad master, you need to switch speeds in time.
I completely agree. Two weeks ago I just bought my first bike from canyon and didn't learn this anyone. I knew there was something subtle going on but I wasnt able to repeat it.
I own this bike/shifters with 2 shift for 15 years and never knew that,lol. Thanks for explaning with very details.
Had no idea what trimming was. Found this video by searching for what the front derailleur was doing. So glad I found this, great practical demonstration. I thought there was a problem with my bike, but it’s a feature!
i know nothing about trimming before watching this video. thank you!
I have been cycling for many years and never knew why it had that extra click. It's one of those things that nobody tells you. Great to know!
I've just bought a pair of basic 2x9 Microshift R9 and couldn't figure out why the rear shifter had an expected 9 positions but the front shifter (labelled "Double") has 3 up and 2 down movements. Now it all makes sense. Thanks for the video.
First time I’ve heard about trimming. Just recently got a new bike with Shimano Sora and still getting used to the shifting. This video has taught me a lot. Thanks SickBiker and a big 👍.
Why is this the first time that I hear about trimming? Extremely useful stuff, thanks for the video!
I literally only just found out my bike has a trim function today by accident! This video was super helpful in letting me know how to use it. Keep up the good work!
Big thanks for the explanation. Just got my first road bike with Tiagra set and had no idea why it does this, now I know it suppose to be like that and what it's good for.
I did not know that trimming was a thing, I recently got a road bike not even a week ago, and when I first shifted the fd I thought it originally had three gears because I had to crank it all the way to shift gears. Thank you this vid was very helpful
Thanks so much for introducing me to derailleur trimming. I never heard of it before and now I know that my shifters are actually working properly. 😂 🤪
Never herd of "trimming" until this video. I thought it was just not shifting properly. I know know there is a reason, and it works. Thanks, great video.
I must say, this is the best explanation how to change gear system. Video angle and explanation was perfect. Thanks for helping.
Thanks for this! I had my bike a year and no idea you could do this. Trimming + some adjustment to the barrel adjustor got rid of the chain rub.
This channel has always been My Go-To channel whenever I needed some information. Of all the channels the SickBiker is "the" direct to the point instructions.
I've owned my bike for 3 weeks and adjusted the front derailleur twice to reduce rubbing. Never realised I could just click a button to make the rub go away
Wow! I did not know about this. I bought my bike almost a year and just now learning about this very helpful function. Thank you so much for this video.
Great explanation and demonstration of how it works, truly appreciated, and keep doing these kind of videos, thank you so much
Thank you so much for this video, they way you explain and show with camera angles is very helpful. I just bought a road bike and learning how shifting works
Best how to channel for cycling on the internet. Thank you!
Very good explaination of trim. And high quality , clear video and sound. awesome!
I've been riding a flat bar road bike/Trek, but not with gold gears or chains. Any way I'm watching this video, very good, very rocket science to me. The bike shop said, here, go for a ride, well I had enough sense to know he's into selling bikes and not worrying about my safety, you SLICK BIKER are into keeping me from killing my self. The entire process of breaking and shifting gears are one big learning curve. The timing took a long time to adjust correctly on my FX 7.9 and I can see I'll need a large parking lot to learn or begin to learn all this. Thanks, your video is very good.
Wow, this the only videos where i learn my bike front derailer problem. Properly explained..thank you
Wasn’t aware about trimming at all, gods explanation!
Agreed. This is best explanation on setting trim for your front derailleur. Thanks!!
This is the first time I've heard of trimming. Thanks heaps
I had no idea there was a trim in the smaller cog position. Thanks! This helped me a lot.
Thanks for this! Helped me get my derailleur sorted out today.
Bought some microShift shifter that has trimming. I was weirded out by this function coz I thought they sent the wrong parts. This video explained a lot why the shifter has more clicks than it should. Thank you.
World class teacher. Absolutely brilliant instruction.
Ahhhhhhh this is what I was looking for. Well done and thank you!
Exactly what I was looking for and it solved my issue. Thanks!
After watching your video I Finally understand! Thank you so much for solving this mystery.
Almost returned the bike. The first LBS didn't have a clue. The second one taught me trimming and I'm happy with the bike. Trimming should be taught in primary school ;)
I just spent 5 hours trying to fix the rubbing on my derailleur. I just needed to trim it :(
Thanks so much for this. Really simple and clear explanation
This video helped me so much with my new Trek!! Thank you thank you thank you!!!!!
I have one of those shifter and didn't know about the trimming. Good to know!
This video is GOLD
Ive been riding for years and NEVER knew this until today. Whenever my gears rubbed, I always move to the smaller chain. Thanks for this video!
Thank you.this episode really informative 👍👍
Thank you for the video and explanation very clear, always had this issue but accidentally treaming and fixes the problem i thought something is wrong with my FD
Greatly explained!!! Thanks
Bought a bike with Shimano Tiagra shifter. I thought something wrong with the shifter. Thank you for the clear explaining on how it works. It is still very confusing to use. I have to think about it to trim left or trim right when shifting gears.
I went to the bike shop earlier, Paid the mechanic and got tutoring on this. Nothing really was broken
Thank you, now I know how to properly used this microshifter.
Wow a month in on my new bike, I didn't know about trimming, I did know about the noise.
Why no one told me about this? Like ever? 😬 I thought I broke something when the trim option started to work on my bike...
So helpful. Thanks. 🤟
never heard before. many thanks to let me know.
I have a Bianchi Intenso with Campagnolo veloce. Triming works great 😀
Thank you foe this video
Great video (again). How about the current 105 and up? They seems to have four positions:
l-trim
low
t-trim
top
hot to use this?
You are the Best, thanks si mucho (y)
Fantastic !
Thanks for your great video on trimming. BTW, about the small lever on Tiagra 4700 right shifter, is the shifting action as dampened as the Sora or crisp as the 105 R7000? Thanks
Super! Thanks!
I bought a Canyon with 105, coming from MTB with Deore SLX, didn't have a clue about the trimming. On the 1st ride, I thought that the front derailleur is completely off, I was thinking to yell at Canyon for sending me a bike without proper front adjustment. But I have noticed the pattern when changing gears, then I checked online and found out that it had a name and it was known as "trimming". :-)
Congratulations I think you are the second video I've ever seen that even acknowledges that the trim positions exist, you join Arts Cyclery in a very select club. The Shimano manuals have all fron derailleur adjustment carried out in the trim positions, at least for 105 and above, never gets a mention in all those other videos..
except that he doesn't understand how a triple works but mmmmkay.... such a clown channel.
Does it also called micro adjustment? thumbs up great as always
thankyou very much
Excellent explnation. So, that means that one do can use the entire combination between chainrings and cassete and no like some people say(that you cant combine small chainring with smaller gear in the cassete).
I don’t believe he is saying that crossing chaining is ok (it will cause problems). I think he is giving good information on how use Shimano STI to adjust your front derailleur.
@@nycticorax5653 thanks for hint👍
SRAM mustn't be trimmed to work properly, right?
I got my new bike this weekend and thought it's impossible to set it up, now I know what I did wrong... Thanks!
I have the same exactly gear and I didn’t know it do that
I’m pretty sure not working on nine
And recently I ruined the gear I Was adjusting the gear as it got poor shifting but I thing I overturned the barrel cable so the rear shifter become no changing gears anymore I feel it like stuck won’t move
I released the cable and put it on again but I didn’t know hoe to adjust it
If any one know what happening would be appraciated
Thanks good video
I just purchased Shimano claris shifters, with a sora front derailleur. Do the claris shifters have trim? I will I not have to worry with my 2x8 system?
Lol I didn't know that. Couldn't get rid of the rubbing. Fixed it by getting the rid of my front derailleur.
Can you also show how sram system work when trimming?
Do you leave the internal routing guide on the cable?
Really :-) I didn't know this. I have been riding my bike for many years and always cursing Shimano. Now I know....
Thanks a lot for this video!! Is there a trim function with MTB derrailure gear systems as well? If yes, how does it work?
No, unfortunately.
Great detailed video! thanks a lot for sharing. look, for the cheapest ones (like Claris), is it possible to add barrels or something that work like, in order to fine tune the cable tension? i had a Tourney that im upgrading and its a pain to fine tune the cable tension by pulling and screwing bit by bit...thanks
You can always add an inline adjuster somewhere - providing your cables are not completely hidden in handlebar/stem/head/frame.
What if the derailleur doesn’t move left (From big to small) when trimming? Mine just got a tune up and the trimming works when I need space to the right but not to the left.
Great video. I have the new 105 r7000 FD. My high trim works perfectly but my low trim is not working at all. Any trips to get that working?
The cable tension is not tight enaugh. If you have cable tensioner screw ,try to turn it counter clockwise 1 to 2 turn
Sick! 👍
I have a Canyon with dura ace 7900, trimming up works fine but not down, it goes directly to the smallest chainring...
So it is normal that the chain is rubbing if you don`t trimm when on the lowest gears (small chain ring - largest sprocket)? I thought trimming is only necessary when the chain is crossing (small chainring-small sprocket and large chainring-large sprockets.
Well damn, I've just re-indexed my gears because I thought they were poorly setup. I've never even heard of this.
amazing explanation. isn't it better just not to cross chain? more efficient, and better rider skills developed.
wow I didnt know this, and I thought my bike is a faulty one lol thanks
Robisz dobrą robotę 👍

I've been riding my road bike for over two years didn't know. Been riding road bikes since 2010 and had no idea. Well tbh the first few bikes didn't have sti. The last two/three since 2014 should have figured it out
Great information but you shouldn't need to lube your cable housings is the only thing I would say. If you are thinking that's the problem, you need new ones. Adding lube to a cable is a short-term fix and will cause long-term problems.
I did not know there is such option on these shifters. does Sora and older models can do the same ?
Yes, my Sora from 2014 did it
My 105 trims perfect on the small ring but can’t ever seem to get the big ring to function properly. Big part of the problem I believe is my bike doesn’t have a barrel adjuster anywhere on the front shift cable. Making it very difficult to fine tune cable tension.
The wire tension on the front derailleur cable is much higher than that of the rear derailleur, I had to put a barrel adjuster for the front derailleur cable because I have internal cabling on the carbon frame (the rear derailleur cable seems to be fine without the adjuster). Also the barrel adjuster may compensate for the cable stretching over time.
I find it difficult too, I can only get it to not rub on either the big or the small chain ring but not both
Anybody remember the triple chain ring 105? The one with the octalink? Haha still have it with the outer cable sti also 105
Thanks for this video which shows how the trim function works. Please can you also make a video with a clear explanation of how to adjust and fine-tune the trim function with the correct step-by-step plan for this?
let's be clear. if you need to use the trim that means you are crossing the chain. so, the thing is, when you hit the derailleur cage, that means it's time to change the ring. the trim is there only to force the cross chain. which you shouldn't. small ring = top half cassette / mid ring = entire cassette minus 2 cogs on each side / big ring = bottom half of the cassette. if you use your triple like this, you'll never need the trim feature. i'm so pissed at that SickClown.
@@JayB-lz6yd thank you for your comment and it is clear to me that it is not good to cycle with a crossed chain and for this reason i never do this. I know what the trim function is for and how to use it. What I would like to know ans what my qeustion is about is how you adjust it correctly with the adjusting screws and the cable tension of the front derailleur.
there are plenty of good videosout there. don't ask him that. he'll not do it correctly. all his videos are like this. always something wrong. you can't trust a dude like that.
There is a way for trimming in the big chain ring to not work. If the cable has to much tension.
Exactly that happened to me.
I have a Shimano 105 group on my bike with 2x11 gears. Should I be able to do it on that?
yes
No
Yes
Hi sick biker, can you talk more about alternative brands(Chinese brands) of groupsets that are unknown for the big public?
I believe that bike industry is controlled by few companies.
We as consumers need more diversity.
SickBiker could if he sponsored by them.
With regards to other Chinese Brands like produce virtually identical in quality groupset parts to the big JAP and US companies, it would be down to trial and error and taking a risk to save money on overpriced premium bike components.
If you are referring to the stuff on Ali Express website, always check the review with pics so you can see what the customer purchased and installed.
What if the trim is not working or not noticeable on the big chain ring?
Check your cable tension. If it is wrong your trim may be eliminated.
If I am understanding this, then trimming is used to stop the chain from rubbing inside the cage. Am I right?
Also, I am thinking that keeping my cadence steady is important to maintain endurance - not just getting into the higher gears as quickly as I can, and "toughing it out" to cover more distance. This would just wear me out quicker. Am I right on this one? I was told when I bought the bike to maintain 60 rpm, maybe because of my age (75). I am trying to prepare for a TT geared to my age, which is a few months away. All comments appreciated!
I have 2015 specialized Deverge,aluminum ,i maintain my bicycle very well,and seem to always have cable issues, I am always conscientious about cleaning and washing . I've tried different cables and lubes, , these internal cable routing seem to cause problem, ,,I've used expensive and cheaper cable/Housing, again with different lubes but always cimes back,
which FSA crankset are you using ?
Not sure but this Cannondale uses BB30 bottom bracket.
What happens if trimming works only on my high gear but not the low one?
How do I enable treaming on Shimano 105
On Claris it will work?
It works on my 2010 claris shifters
I dont get it but never had a road bike yet (unfortunately)
Can this be done in Claris FD and shifter?
Yes
All modern Shimano road groupsets have this trimming function.
The trim did not work on the low ring on my bike after lbs replaced the cable and I did also not have loud enough click when trimming. I found out that LBS did not set the low limit screw properly after using to get correct cable tension so it was rubbing on the low/low gear. Well I don't blame the lbs and the mechanics everyone at the store needs to work fast so they can fix as many bikes as possible so small errors like that can happen.
What did you end up doing? I'm facing the exact same problem after having the workshop replace a cable. Now it's rubbing on the four largest cogs while in small chainring and also trim is not working.
