- Carbon AM wheels
Using CNC machines is, in itself, no guarantee that a good product is being produced. It just means there is far more ability to churn out a poor quality product faster and repeatedly. I cringe when I see adverts promoting the fact something is CNC’d as some sort of endorsement of high quality or good design. It has nothing to do with that. All CNC machines do is give you the ability to manufacture high precision products repeatedly and reliably. But it’s still a case of crap in equals crap out.Posted 4 years ago
Lots of talk aboput Light Cycle rims.
That’s interesting. I’ll see if I can catch the guy who wrote the report and ask him about some more details.
The cross section of the SC rim is very similar to the cross section of the LB rims. This is the development of the 650b rims (new on left):
Worth noting that the carbon rims tested are only 17mm inner width but the Crest is 21 and as they are around the same weight the Crest is doing a good job of keeping the same weight but wider. I would like to see the testing repeated with the new wider carbon rims with better manufacturing at the ‘UC’ ones in that report seem to be quite early models. It does show that even poorly made carbon rims are still pretty robust though.Posted 4 years ago
Superstar paid me with a pair of carbon wheels which I’m very happy with.
I’d be happy to do comparison of all sorts of wheels, but that’s up to the rim manufacturers. I just tested the rims requested. The results showed for the failure mode considered, carbon is stronger than aluminium and that the quality of the carbon matters.
I only posted on this thread as I was searching the internet to pass some time, I noticed this thread and lots of people advising buying cheap carbon rims. I just thought, based on my experience, I’d say that this might not be the best route.
njee20, that’s a particularly agressive post. What the hell has the fact I sell my old parts on this thread got to do with anything. Do you think perhaps I’m a thief!
I’m an engineer trying to find some interesting chat. Not start a fight.Posted 4 years agowobbliscottMember
To be fair to the cheap Chinese rims, the test show they’re at least ad good as the Alu rims. its no surprise they’re not as good or strong as the more expensive carbon rims, but you wouldn’t necessarily expect that anyway. But the question really is not how strong are they, but are they strong enough, and benchmarking against the Alu rim the cheap Chinese rims do appear to be strong enough.
In my mind things can be too strong and tough. If you damage a rim, you wan to know about it. If its so tough that it can be damaged and weakened with little or no visual signs then that is potentially dangerous as you’ll keep riding on it. Seems to me the cheap Chinese rims might be a decent punt for the vast majority of us who are nowhere near pro standard.Posted 4 years ago
@phutphutend – without saying too much on a public forum we do some work for you guys over at the you know where. I’m wondering if I’ve spoken to you about cycling in the coffee room now.
I’m a big fan of composite rims and would love to get involved in some development at the ‘you know where’ if there was any interest, both in terms of optimising the processing (what we do) and protecting against damage (what I specifically do).Posted 4 years ago
33mm light bicycle am rims laced to hope 40t hubs vs superstar am rims laced to tesla hubs, which ones the right choice? Superstar are 100g ish heavier but going from past experiance a lot of that is probably in the very heavy hubs (often much heavier than claimed) so isnt as big a deal as weight in the rims. Does anyone have a true weight for the superstar rims?Posted 3 years ago
Got the superstars for £450 so cheaper the light bicycles completes and arrived next day. 1660g for the carbon AM rims laced to teslas with sapim cx ray spokes and alu nipples. Happy with the weight considering its all in the heavier than claimed superstar hubs, rims are only 400g. Got the tech graphics with red nipples and red hubs and these are the sexiest thing Ive ever laid my eyes on
