- You don'y always have to start from scratch! Armed with his trusty spoke wrench, WH-1 and just a little gaff-tape, Calvin salvages what he can from a fat bike wheel and performs a RIM SWAP. All on camera! Wow.

I love Calvin's presentation style, he comes across on video so brilliantly.
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
How is it that this dude makes everything look so easy?
editing. The part where you battle stuck nipples is left out 😂
Years of doing it every day..
As a mason told my father once, the first 50,000 bricks are harder.
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.
your the best calvin,salutes from phoenix arizona to all the team
Man I just wanted to say thank you for all this knowledge you are sharing with us
Bonjour Calvin c'est génial comme processus merci beaucoup au-revoir et à bientôt Thank you 😊
My front wheel has done over 13k km now, still going strong 😄
Yet another very useful tutorial, thanks.
Love goes out to this guy,,, he even has park tool scissors 😂😂 keep up the good work
OMG you must be psychic. I just damaged a rim last week and now you have given me the confidence to do this!
Awesome thank you Calvin!
I did not know this. Thanks for your video
I've used this same method for dirtbike rims.
Great vid!
👌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👍
i was thinking of a rim change, thanks for the tips
Lovely to watch😀
Thank You :)
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!
Excellent
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.
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.
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
This guy has been building wheels for 30+ years and taught it to bike mechanics. says it's almost impossible to over-tighten spokes:

Lucy you had a rim that fit. I got a good deal on a new wheel from the work shop. :)
Never gona do it, but loved watching.
That's wheelie cool 😁🤙
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.
+- 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.
seems like a good idea
Can we install front disk brake on road bycycle with 27" rim ?
Can you please make video how to put dynamo in hub from one wheel to another
Bash it round with a wood block and a soft-faced mallet, put a tube in it. That's what us poor folk do.
Nice
I'm still curiously looking forward to more of looking inside my tire with sealant videos
There will be at least one more coming!
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?
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.
do think it would be cheaper to build your own wheel or buy that same wheel with the same exact parts already put together?
amazing :3
Great vid, any chance of a video showing how to replace a 8 speed hub for and 11 speed?
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.
I can imagine this being a hell of alot harder on a 20 inch wheel with 48 spokes.
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.
that was True, -man!
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?
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.
I have an unrelated question... Sanding your brake discs is a fairly new concept to me... What is your take on that?
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.
@@parktool thank you!
What about a road bike rim with thousands of miles? Do I need to replace the spokes? And can we really reuse the nipples?
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
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!
@@parktool thanks for the reply
Cant the dent be bent back? Run tubes in it later
Possible, maybe, but this idea here was to teach the transfer.
@@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
I'd do a rim swap like 30 years ago, but I'd taped all the spokes, then made the rim swap
Is it possible to straighten out and salvage that old rim at all? Or is it totally dead from that crimp?
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.
Is that the TS-TA connected to the WH-1?
OK, I see at 8:08 he says that it is. Neat trick
Why yes, it is. An accesory option for your Wheel Buddy.
Pls also do a hub swap from freewheel to cassette
A "hub swap" is simply building a wheel, as if from scratch. All the spokes must come out. See ua-cam.com/video/X5gs00ttvdg/v-deo.html
I am truly impressed, but what is the practical gain for a rider ?
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.
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.
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.
calvin please stop breaking bike parts to make videos. We both know that rim was perfect before filming
