Beautiful wheel and it's obvious that a lot of thought has gone into the build. I'd like to ask you though, why weave the spokes? At one time, bicycles made at Nottingham had woven spokes and bicycles from Coventry did not. When I worked for Pashley, a very experienced engineer told me that whenever he bought a new bike he had to take the wheels apart to un-weave the spokes and then rebuild them again. I thought about this and think he is right; there is no evidence that weaving is superior and it means that a spoke can't be plucked to hear it's tension.
@@Bicyclehub hi thanks for watching and commenting. These wheels have a 3 x spoke pattern which we commonly use as well as a 2 x pattern on lower spoke count wheels. Whilst not crossing the spokes has its place I.e on smaller wheels and lighter weight performance wheels, 3 x and 2x patterns are proven to be one of the strongest lacing patterns without adding too much excess weight. If someone decides to take brand new wheels apart and relace them it sounds like they are only doing it to try to prove a point or they have far too much time on their hands 😂 Hope that helps
Really interesting. Is it typically the rim that determines the maximum load on the wheel? What role does number or spokes play? Thanks.
@@benatkins2106 thanks for watching and glad you liked it. It is mostly the rim but when being able to take such a heavy load you have to think about spoke and hub strength too. The spoke count doesn’t effect the capacity of the rim but the more spokes a wheel has, more load can be spread over them. 👍
@@veloworks9266 Thanks for the answer. All good to know.
Sorry, but the system weight rating as given by DT Swiss is a pure nonsense - you don't know the actual weight distribution!
The only proper rating is axle load. Majority of the rims are given 60-65 kg of axle load. Some are given up to 120 kg - but is this really true? - Who knows?
Regarding the front wheel:
If you do not use panniers on the front and have the most basic suspension - anything goes there for 5 years, and even more.
What breaks and really matters is no the back:
And still - for 5 years anything goes here too.
It's even better to have a weak rim - it will start cracking - but slower than than the spokes braking with a strong rim.
The warranty is completely irrelevant. If it breaks - you replace it with the same - than it breaks again...
The problem is: How do you build it so it does not break?
What I see here is first: strong rims and strong hubs - but that's a common sense.
The non trivial things go with the spokes:
You suggest Sapim Strong (2.0-2.0-2.3 mm)
Some people suggest Sapim E-Strong (2.3-2.3-2.6 mm)
And some even suggest Sapim Race (2.0-1.8-2.0 mm)
And what the spoke tension needs to be?
Usually minimum non drive side is considered 65 kgf, and maximum drive side is considered 130 kgf.
@@2L40K hi thanks for watching. What we have here is a lovely set of e-bike wheels built within the specifications of all the components and we have supplied rims from a trusted brand who have been around for almost 40 years. Through consultation with the customer we have built them the perfect set of wheels so they can enjoy cycling. It doesn’t need any more analysis than that.
At 4:05, one thing's for sure. Paul is built... sweet. ♥
😂😂 I agree David ! From, Sarah 🤣
@@veloworks9266 You see !!! We've got a second motion. It's official. "Paul is built sweet."
