I love this dude! He has helped me so many times. I have an I9 en300 wheel set. I thought I'd never break one of those spokes, but sure enough I bent one badly. I didn't know the drive side uses a different length spoke, so that's one thing I learned. Also, I never would have thought to cut the rim tape. I was just going to take it all off, then retape it. It's the simple things like this that are so helpful. Thanks for all the tips!
A little off topic, but do you know a good spoke calculator for straight pull spokes? I've looked online and not much info, where as Calvinpedia always seems to deliver ;-)
If U don't have locktight, linseed oil work even better IMO. Lubed for a day or two before it dries, so U have time to tweek the truing after stressing the wheel.
@@MaQuGo119 bmxscape is wrong. Let's quote Jobst Brandt :"Grain alignment in drawn wire is longitudinal and cold forming a head onto the end of a wire disturbs this uniform structure. That is the main reason why this is the weakest place on a spoke. The elbowed spoke does not pull directly on the head, and therefore, transfers most of its load to the flange by a stronger part of the spoke." To sum up, traditional j-bend spokes are a better design.
Thread locker is an anaerobic compound that cures in the absence of air and in the presence of an active metal like steel. If used in a situation where there is very little active metal then primer is required. The locker only starts to cure once the fastener is tight and air is squeezed out. In that environment they typically fully cure in 10-20 minutes.
Did this spoke break due to the chain grabbing it with a outer link due to the derailleur getting hit and bending the derailleurhanger way pass the b-tension setting allowing the cain to drop past lagest cog on the casette and so grab the spoke with a outer plate?
No, the spoke has no cut mark or burrs, and the anodizing looked normal. We suspect it was impact during a fall on a stump....or some other blunt instrument.
Hmm, I always just add a full loop of rim tape. Better safe than sorry. Also it usually helps with seating the tire. Manufacturers are so cheap, I had several wheels (DT swiss, i9 and Race face) start to leak because the single layer just fails at the spokes. So to begin with, I always do 2 layers.. Tape is cheap, tires and rims are expensive and sometimes by the time you realise you lost pressure, you already ripped the tire and dinged your rim too :(
i wonder y calvin didn't use the wheel holder (cant remenber the right name of that tool, mounted at the desk) while he inserted the spoke into the rim. isn't it usefull for such jobs rather then having the wheel oldfashen wobbeling at the desk? maybe he's use to his habits when he was wheeling rims back in the days. i like your tech tuesdays, never miss greetings from germany
I can't wait for a manufacturer to make a bike without connecting the hub to the rim. That will be interesting... magnets? antigravity? That will be the ultimate in soft suspension.
Excellent work Calvin👍

Looks easier than I imagined it would be. Thanks Calvin!
I'm always fascinated by all the tools in that shop. I love the wheel holder he is using, and looked it up. It's $129, ouch.
Always enlightful time getting the tips from you !!! See ya
Ive got i9 wheels and this is very helpful. Thanks.
I'll be staying w/ stainless steel spoke be they straight pull or J-bend
You are still the best out there.
zen tuesday...thanks calvin!
Good stuff. I9 recommends boiled linseed oil for the prep, not thread locker.
Bonjour mon cher ami Calvin 😊 Thank you very much 👋😊
Genius music, I love it. What is it?
Do you tension these just from the rim end, or from rim and using the hub-end hex? Avoiding wind-up?
True from the rim. The large spoke diameter effectively eliminates any significant wind-up.
A little off topic, but do you know a good spoke calculator for straight pull spokes? I've looked online and not much info, where as Calvinpedia always seems to deliver ;-)
Did the cassette have to be removed, or was it removed just for recording the video?
James Poe if u have a long 2mm hex no if not yes
Correct. Sometimes things are done for educational purposes. Here, to get a better view of what's going on.
It's okay to use threadlocker in the spokes? Thank you
try watching the vid.

@@GeekonaBike lol..
Does this system has benefits? or is it only for them to charge more?
typically the weak point in a J bend spoke is at the bend, by removing the bend you remove the weak point thus making the spoke stronger
@@bmxscape thanks

Boss, do you need to wait for the thread locker to dry up before truing it? I bet this design only the nipples are the turning object right?

So if the patch does not hold ( yes, i saw the comment that it did) would you just retape the entire wheel?
If the patch failed, a complete removal, clean, and re-tape is the process.
@@parktool What sort of tape did you use ?

“ I am guessing this is from an impact.”
I can’t see the hammer on the peg board, yep an impact.

So, I wasn't the only one wondering that?
But did it seal first time!?!??!?!? The tension is killing me.
The pressure is just killing, isn't? Yes, sealed right up.
@@parktool Phew. A relief. Thanks gents.
Yes, Thanks. I couldn't sleep last wondering. Sometimes I don't like having a "need to know" mind.
@@gastonlagaffe7547 Well is he is the spokesperson!!

Lol no
i thought that it was impossible to break a i9 spoke
All spokes can be broken. I ended up unclipping while sprinting, foot came and hit the wheel as I tried to turn the wheel to recover. Spoke snapped.
Me to
This one broke from impact in a crash. Aluminum like any material can break with enough load.
I just bought a used bike w four missing spokes
Ok
"Suscribe"???
Never ever buying this type of wheels, what a pain in the rear.
Terrible design :D
You’re just mad you can’t afford it 😂
Lol don’t take it personally I’m just making fun of how expensive they are
