Definitely! Maybe separate sections such as frames, batteries, wheels & components would be my suggestion.
This section allows you to view all posts made by this member. Note that you can only see posts made in areas you currently have access to.
and are way stiffer.
I don't know, my friend has a Cannondale Scapel and has broken that frame along with cracking his Cannondale road frame. Both were purchased from LBS who is a Cannondale dealer. I believe all carbon frames are subject to breaking. That's the argument for some for purchasing a Chinese frame, it's disposable if you break it and didn't spend $2000-$3000 on a bare frame
That's nonsense. The NECO headset is a good headset. The best you can get for the money. The CC isn't as twice better than the NECO. When there's water or mud in the headset, the CC is warned out as quick as the NECO.
I've got multiple NECO headset on stock. If one of the current headsets is warned out, I'll replace it. Once in a year or two. We're all riding NECO (three chiners, three NECO's). And they last at least a year without problem.
If they get back to me quickly with information I should have one built soon. So far I've too many tech details to cover before ordering it.
That tells me that low-end material, probably used here, is a weaker material then what you would find in latest frames from Cubes, Cannondale, Specialized, etc...
Especially (danger rant following) once Chinese businesses realize that proper websites with prices information and not thousands of emails sent forth and back are the way to sell stuff.
The weight listed on iPlay's website is perhaps a bit optimistic at 1525g. The three sets I have in my hands averaged exactly 700g (front) and 890g (rear). The range on the three front wheels was 3 grams. The range on the rear wheels was 10 grams. Not bad at all.
So why such a W I D E wheel for an ultra-light XC machine? Well, a variety of reasons. Traditional XC rims have an inner width of 19-23mm. These rims are 26mm, In the past two years, the industry has been moving towards wider rims across the board, from DH to XC. And a lot of this has to do with the advent of tubeless tires. A wider rim has several advantages:
1.Allows sidewalls of tire to stay more "vertical", offering more support while cornering, even at lower pressures. As the two beads more further apart, the tire is more supported in the rim rather than pivoting on the rim when the beads are close.
2.Allows a smaller width tire to perform as a wider tire. This allows the use of a smaller tire casing for weight savings which can easily offset the small increase in rim width. For example, a 2.2" tire might act as a 2.35" equivalent.
3.Increase wheel stiffness.
4.Large reduction in "burbing" of the tubeless tire on the rim at lower pressures.
5.Increase traction and comfort from reduced pressure needed.
Or at least this is the theory. I will see how this plays out in practice. Perhaps it is all marketing, but it does make good sense on paper, so I suspect there is some truth to it. The above reasons aside, I am looking forward to the reduction in rotational weight over my previous wheelset (~2100-2200g!) and a huge increase in robustness and stiffness over my previous alloy wheels. Opting for a more traditional width rim would have yielded a decrease in weight (marginal), but I suspect the benefits of the increased width will offset the ~100g total per wheelset penalty.
We also decided to try hookless rims on this build as well. Many of the industry players have started to convert to hookless on carbon. Again, there must be a good reason? Well there is. Hookless beads allow for an easier/cheaper to manufacture rim. The rim edge also gets more continuous carbon fibers so it is stronger against impacts than the older hook design
I just watched a ridiculously and surprisingly good movie called "Afflicted". I don't want to sat too much about so I don't ruin it, but one of the best movies I've seen in quite sometime. Perhaps because I had never heard of it and therefore had zero expectations, but checking the online reviews, I am not alone in my praise for the film.
Another really cool off beat unexpected great movie is "Let The Right One In" (the foreign version with sub titles is much better than the English version)
Def check both of those out!
