Excellent clear instructions without the hype and macho nonsense sometimes accompanying cycling video
This Calvin dude has become the face of Park Tools!!!. Great easy to understand videos.
Thank you for the video. I particularly enjoyed the fact that even the Sharpie was in regulation Park Tool blue.
Very useful tricks for sizing a Campagnolo chain correctly-best video I've seen - thanks!
Thank you for everything you and your company do. "Teach a man to fish...!"
Calvin, thanks for doing these videos. I'm really enjoying doing all my own wrenching and your video tutorials are extremely helpful.
I just purchased my 1st multi-gear bike [Giant]. Your videos are so clear and full of info. Keep up the good work.
Good video, thanks! This method of sizing worked well for me with early 90's 7-speed Ofmega components.
I watched 3 separate videos to reach here....... this is madness! All this could be fitted in one "Replace/Install new" chain video.
I am using the C10 chain on the Veloce groupset. When at small/small, my options seem to be chain rubs against the pulley, or remove a link and the gap is larger than 15mm, which way do I go? Or is there something else I an change?
Go with the larger gap. No not allow it to rub.
Couldn't get my 10 speed with medium cage RD to get in that 8-15 range. it was either rub or with 1 link of chain shortening I was above the 15mm . Works fine with the larger than prescribed gap.
Are the instructions slightly different for Campagnolo triple rear derailleurs?
Remember, if you're using a chain with a quick link or missing link, you may have to remove an extra link from the chain that you're shortening to compensate.
Does this apply to vintage Campagnolo components? Specifically 6 speed with vintage Super Record from the 70s-80s.
Yes it does. Same process.
Love your videos - always so clear! Thanks :-)
Thank you for sharing
I was able to get within the 8-15mm range on the smallest rear sprocket and the smallest front chain ring, but now the chain is too short to shift onto the largest front chainring. I have 3 front chainrings. I wonder if that's the issue. The chain's as long as possible without lessening that 8-15mm gap though.
So what does it mean if the gap is closer to 2cm from chain to chain (1.5cm from chain to cage). There is no sag in the lower chain and all my gears operate quietly and smoothly
If there is not sag, and all gears are good, leave it.
@@parktool Thank you!
Hi, does this procedure apply to the older 8 speed components? I have an 8 speed Record drivetrain and a new c9 chain.
thanks
Yes, 9 spd chains are also compatible with 8 spd components.
Hi. Excellent viddy. Does this process apply for medium - long cage derailleurs, or are there any modifications?
The cage length will not change the process in the video. All stilll holds true.
I cut my chain to short as I did not account for the masterlink. The distance is 19 mm. Will changing from 28-11t cassette to a 25-11t cassete solve the problem? As in, is the campagnolo 8-15 mm gap just for smoothness?
Hi, Can I use this method with a SRAM chain with Campagnolo drivetrains ?
Yes - and I hope you did, now that Im noticing the one year span on my reply :-)
Whats your opinion of a quick link on a campy chain. Thx
We love it! Campagnolo is now shipping them with chains.
@@parktool Thanks so much!
Hi, I have a question. I have both a "modern" slant parallelogram campy record derailleur, as well as a vintage campy (1983-84) parallelogram record derailleur (as well as an early 70's NR parallelogram derailleur. My question is, how or what criteria do I use to size the chain on the vintage bike?
I put Campagnolo Chorus groupset at my bike in Campagnolo dealer workshop...they put my 11s chain with a problem...the end of pin looks inside and finds in gears...get noise and cassete is full of scratches...at climbs it s really disturbing...they dont recognise their mistake...so i take park tool chain tool and i fit a new one...problem solved...if you want perfect work do it your self...with Park Tool 😉
Informative video. Thanks for the info. Do you cut the chain at the same place if using a connecting link instead of connecting by rivet?
The finished length will be the same when the connecting link is included, but it is not cut in the same place. When sizing, put in one side of the connecting link to account for its length. Then they become effectively the same for sizing and cutting.
Thank you. So if I don't have the old chain to measure by I just cut 1 link shorter to account for the length of the connecting link.
Is this method for 11speed drive trains only or is it for all drive trains?
Aaaguilarrafael It's the method I use for any drivetrain with a rear derailleur.
How do you size a chain on a bike if the bike does not have a chain on it from beginning okay.
is this tool can compatible Campagnolo supper record 12 speed chain ????????
Sure is!
Why exactly do we need start routing the chain with the side of the two outer plates?
Technically you can start routing it however you find most appropriate as long as the side with the outer plates is going forward on the top. These plates are designed to hold the new rivet. You should never remove links from the side with these plates and the plate should always be on the leading side.

How to buy thecone set of park tool?
We have distributors around the world. Here is a link to find a retailer near you. www.parktool.com/trade-resources/worldwide-distributors
Make sure the end of the chain to be removed does not contain the master link, if applicable.
Don't ask.
💘💘💘
Good info, but for God's sake, it's pronounced "Cam-pan-YO-lo". If that's too much, just say "Campa" or "Campy".
that gets painful very quickly
