World Sport Chain Fix Part Two: We Need An Idler | Tech Tuesday

[@nosb10]

anyone else here interested in hearing Calvin's whole story?! I'd be super interested to hear how he got into wrenching and how he got his start with Park Tool!

[@Cledus2000]

I thought I read he was the bike mechanic for the 1984 men's Olympic team. I could be wrong. But if that's right, that puts him up there with the best.

[@micahyarbrough5513]

@nosb10 There's a good interview with Calvin on the Bike Karma podcast from probably within the last year or so

[@DrewLevitt]

The World Sport videos really want a playlist so people can watch the bike take shape, start to finish!

[@parktool]

Ask and you shall receive! kzbin.info/aero/PLGCTGpvdT04TJkgVwn0H5HaS9triMmifq

[@DrewLevitt]

@@parktool Thanks!! You truly have the high-quality, blue-vinyl-dipped tool to my heart.

[@galaxychocolatebar]

@@parktool did this world sport project ever get across the finish line? seems your playlist includes some unrelated videos too! tx

[@lucasbrandt8660]

I've been all week having issues with my bike so I binged almost all tech tuesday and other video procedures. In a few days I'll be checking a buddy's bike before taking it to an actual mechanic because we're short on cash. Park Tool's videos have sparked my interest in being a bike mechanic, which, if I told my past self that, he would've laughed his ass off, because a week ago I didn't even know how to ride a bike

[@WowRixter]

Calvin is an artist at work

[@namdarbolour9890]

Calvin, you coulda used an ordinary toothbrush instead of that giant Part Tool brush, ha ha! Also, the idler looked too tight to me, making rear wheel removal harder and adding friction. Two more links on the chain would be better. Not complaining. These are great videos and a great contribution to the bicycling community. Thank you.

[@bikeandsee1647]

A delight to watch. a) it also has been of iterest to me to see that you do not use a Magic Link to connect the chain. b) it would have been of interest as well to hear you about the specific sprays, oils, psstes you used. Cheers.

[@dcraft969]

Always look forward to the videos, I’ve learned so much!

[@EriebyCycle]

I miss that tab every time.

[@allsam3407]

Can you explain to me how you adjusted the chain alignment please ?

[@paisfr]

Bonjour Calvin , Je vous souhaite une bonne année 2022 💫👍😊✌

[@BillBlandford]

That frame has campy style drop outs. You could get proper single speed tension without an idler. Removing axle, flipping freewheel spacer to non drive side and redishing the wheel allows for a proper BMX freewheel to be installed with good chainline too.

[@parktool]

The dropouts are not "campy style". The drive side does not permit horizontal movement. Move spacers is a good idea, but not needed in this one case.

[@Thecrazyvaclav]

Park have watched RJ the bike guy and thought we can do that

[@holzmann8443]

Park Tool helping us salvage junkyard bikes after the upcoming financial apocalypse! Very thoughtful.

[@forgetyourlife]

Unfortunately a lot of the tools needed to work on these older bikes are no longer made by Park.

[@CyclingLifePT]

I know you guys like to use your brushes, but for real, a tooth brush would be way better for cleaning those small, hard to reach parts/areas where your humongous brush cannot reach. Other than that, i was already expecting he would be playing with the max/min screws of the derailleur, i just did not expect it to go so much forward. Overall: Nice job!

[@Cledus2000]

Very true. But it is park tools channel. That's why you see it an official park tools bolt bowl, lol. Seriously, they make great tools but they are expensive. He probably has $8.7 million worth of tools behind him there.

[@purabici]

Thaks for all The info!

[@davidburgess741]

I would always use a master or quick link even when it's only 5 or 6 speed chain. I was around when there was no good alternative and a few came apart!

[@forgetyourlife]

You were doing it wrong then. 5,6 and 7 speed chains never needed one.

[@Pulverpojken]

7:10 Did he really pour chain lube on the mounting bolt for the tensioner? Am I stupid or is this not what you should do? I feel like you should put thread lock on it and not chain lube...

[@edumardel]

11:17 el tío Calvin doing it great even in creating new words / Hey guys, you should do a featuring with Comet Restoration channel

[@mcbaldoz7555]

Can someone help me with my problem, when i pedal my roadbike and try to freewheel, the crank and chain and cassette spins with the wheel like a fixed gear bike. How can i fix this? Many thanks.

[@parktool]

Either the bearings in your freewheel are seized up or there is build up of something behind your freewheel that is preventing it from freely spinning. Spoke protectors, grass or a shoe string behind the freewheel could be what you are dealing with. Inspect this and see if there is anything you can see.

[@Navalbird_48]

How much would a front derailleur replacement cost? Does it vary with the bike? Just curious

[@MusGym-official]

Yayyyy tech Tuesday

[@모빌란트]

Wow old parts

[@type17]

Old but great parts - Suntour made lovely derailleurs and other parts, with some very imaginative and clever designs

[@bmxscape]

and all it took was some lube to make it work perfectly again. i love old stuff, come from a time where everyone wasn't fascinated with plastic and saving every half a penny they can

[@martindelgallego5809]

U shd hv put the CHAIN on the Derailleur Pulleys and the Chainring b4 you actually cut it to get the right amount of tension. The Derailleur looks to be stretch to its max limit. Not good at all.

[@xawerionify]

This red rag has wrong color! It should be blue. You should sell some Park tool RAG-1 :D

[@ezequielpiacenza3776]

👌👌👌✌️👍

[@theshadow8008]

I agree with cyclinglife, parktool mechanics can do better than that, the brush is way too smalll, calvin dont want to waste degreaser, i mean its parktool man! LOL!

[@joseealpamayo9106]

Jamas comprare nada a una empresa que sus empleados no tengan un sueldo digno y derechos.Que tal os trata parktool?
