Rim Swap | Tech Tuesday

[@alexdehotot2712]

I love Calvin's presentation style, he comes across on video so brilliantly.

[@MrMeddlinG]

How is it that this dude makes everything look so easy?

[@oftankoftan]

editing. The part where you battle stuck nipples is left out 😂

[@Scott62ebiker]

Years of doing it every day..

[@markfisher7962]

As a mason told my father once, the first 50,000 bricks are harder.

[@Rob-fe9iu]

If you straighten the old rim a bit and put a tube in the tyre would this not save lots of money and resources and time.

[@paisfr]

Bonjour Calvin c'est génial comme processus merci beaucoup au-revoir et à bientôt Thank you 😊

[@jsrocker248]

They day that Calvin leaves park tools or retires is the day I riot, this man is a national treasure to all the biking community

[@AlejandroGarcia-my7hb]

your the best calvin,salutes from phoenix arizona to all the team

[@FlyPsiche]

Man I just wanted to say thank you for all this knowledge you are sharing with us

[@tobegan3753]

Awesome thank you Calvin!

[@kurtbargar1618]

Love goes out to this guy,,, he even has park tool scissors 😂😂 keep up the good work

[@singletona082]

Yet another very useful tutorial, thanks.

[@freedcorporateslave]

OMG you must be psychic. I just damaged a rim last week and now you have given me the confidence to do this!

[@mustafa_rasooli]

I did not know this. Thanks for your video

[@JamsTomatoReviews1]

I've used this same method for dirtbike rims.

[@Tntdruid]

My front wheel has done over 13k km now, still going strong 😄

[@stevebennett3587]

👌I always enjoy watching your videos, if you can do it yourself its great, a lot of bike stores won't have time, and you end up buying new wheels👍

[@davidburgess741]

Done this before. The real fun starts when you rebuild a wheel that was cross 2 as cross 3 with longer spokes. It's so easy to get the key spokes wrong at the valve hole!

[@ctcboater]

You can decrease those stress cycles by keeping all the spokes tight. That's why bolts in critical (cyclical) positions should always be torqued to their maximum.

[@oftankoftan]

Indeed. It's very hard to over-tighten a spoke. worst case scenario you popped a spoke or the rim didn't hold up to the nipple pressure, and now you know what to replace. I always build my wheels until the spokes creak like a horror movie.

[@bmxscape]

when you torque it to its absolute maximum and then apply extra stress by riding the bike that's when you break even more spokes

[@oftankoftan]

This guy has been building wheels for 30+ years and taught it to bike mechanics. says it's almost impossible to over-tighten spokes: kzbin.info/www/bejne/jobUpp9maM2VkJo @ 33:20

[@biesczad]

Thank You :)

[@johnmoug5149]

Lovely to watch😀

[@wasifzihan4662]

i was thinking of a rim change, thanks for the tips

[@billkallas1762]

Matching the ERD is the most important thing. I once crunched a Mavic Cosmos, and replaced the rim with a tubular rim with the same ERD.

[@oftankoftan]

+- 2mm is fine. I went from 17 deep rims to 19. Works like a charm and the rims are double-butted so the spokes sticking through isn't touching the tube.

[@arnehusby1420]

Lucy you had a rim that fit. I got a good deal on a new wheel from the work shop. :)

[@kengwaimak2129]

Never gona do it, but loved watching.

[@deanpurcell7771]

Great vid!

[@SummeRulz]

I'm still curiously looking forward to more of looking inside my tire with sealant videos

[@parktool]

There will be at least one more coming!

[@zerrocoolcp]

Excellent

[@dianuj3655]

Can we install front disk brake on road bycycle with 27" rim ?

[@james.8985]

That's wheelie cool 😁🤙

[@mattgies]

0:25 you can see the wheel is wobbling on the WH-2. Why are the parts for this tool not long enough for a 197 mm fatbike hub? I've been thinking of custom machining a longer part but I wish the tool had just come with a long enough piece in the first place.

[@jeffpoirier5127]

I was wondering if you could use any hub and respoke to wider bigger rim? If a spoke is too long, can you add more threads and cut the extra off?

[@parktool]

It's possible but not practical for most. In those cases you will fully disassemble the wheel to make those modifications and then build the wheel.

[@marka2193]

Great vid, any chance of a video showing how to replace a 8 speed hub for and 11 speed?

[@parktool]

Soe hubs can be converted but in most cases you are going to be lacing a new hub into the rim. At that point you maybe should consider a complete wheel. Or at least should compare the cost. Or, use a Sunrace cassette that may fit onto your 8 speed hub.

[@gordonplatt1174]

How big of an ERD difference is acceptable? Assuming the original wheel was built with the correct length spokes, could you safely swap to a rim with +/- 1mm ERD difference? 2mm?

[@parktool]

Good question. Assume spokes were perfect. 1mm smaller ERD would be fine. But check spokes before loosening. They were too long, 1mm larger might be better.

[@모빌란트]

seems like a good idea

[@NonLegitNation2]

do think it would be cheaper to build your own wheel or buy that same wheel with the same exact parts already put together?

[@eufemiaaguada]

can this work with big rim specs?

[@IgoOrLee]

Can you please make video how to put dynamo in hub from one wheel to another

[@Leviathandk]

I have an unrelated question... Sanding your brake discs is a fairly new concept to me... What is your take on that?

[@parktool]

It can help clean them. Use a fine grit, laid flat on a table. Gently rub each on the paper. It does remove some material.

[@Leviathandk]

@@parktool thank you!

[@Manetty6]

that was True, -man!

[@rhyeonjoplo464]

hey calvin i have a question do you advise to mismatch the holes of the rim and hub?, for example a 32 holes hub lace to a 36 holes rims

[@parktool]

That is not advised. Running a 36h rim on a 32h hub or visa versa is not an easy thing to do and typically leads to an unstable wheel. There are other combinations that can work though!

[@rhyeonjoplo464]

@@parktool thanks for the reply

[@MorbidThrasher666]

I can imagine this being a hell of alot harder on a 20 inch wheel with 48 spokes.

[@cincofr7079]

Nice bro🇲🇦👍

[@bikeandsee1647]

I am truly impressed, but what is the practical gain for a rider ?

[@parktool]

None, if the ends up the same as a full rebuild. It is a simple way to get a new rim without knowing how to lace.

[@Sam-fb8fy]

Nice

[@luisfernandezquero5787]

I'd do a rim swap like 30 years ago, but I'd taped all the spokes, then made the rim swap

[@wjlasloThe2nd]

Is it possible to straighten out and salvage that old rim at all? Or is it totally dead from that crimp?

[@parktool]

The initial impact that bends a rim like this causes the aluminum to become brittle. When you attempt to bend the rim material back into place it will typically crack or cause a weak spot in the rim asking for a problem in the near future.

[@driventomadness117]

What about a road bike rim with thousands of miles? Do I need to replace the spokes? And can we really reuse the nipples?

[@oreocarlton3343]

Cant the dent be bent back? Run tubes in it later

[@parktool]

Possible, maybe, but this idea here was to teach the transfer.

[@oreocarlton3343]

@@parktool I know that rebending rim walls is not common today, but it would be cool to see your take on when to do it and how

[@20.purvensalve50]

Pls also do a hub swap from freewheel to cassette

[@parktool]

A "hub swap" is simply building a wheel, as if from scratch. All the spokes must come out. See kzbin.info/www/bejne/jmbKpGNmqdmpmsk

[@trailbotapp]

Is that the TS-TA connected to the WH-1?

[@trailbotapp]

OK, I see at 8:08 he says that it is. Neat trick

[@parktool]

Why yes, it is. An accesory option for your Wheel Buddy.

[@johnpaulmakowski7464]

I love Park Tool and Calvin expertise and instructions. But is it worth it to do a rim swap instead of just buying new? Thanks.

[@palooza90210]

Usually depends on how nice the hub is. Wouldn't want to re-buy a new wheel with an expensive industry 9 hub just because the rims dinged.

[@funkyfreshanalog3043]

amazing :3

[@nick37781]

calvin please stop breaking bike parts to make videos. We both know that rim was perfect before filming
