Has anyone tried these out?
Hi Guys,
Has anyone had a chance to try these out yet? I'd be interested to hear some feedback, as they are quite pricey to take a gamble on. I'm not aware of any other xc/enduro rim this wide, but I could be wrong.
Cheers,
Pete

xc and enduro are 2 different things... you wont be using a 41mm wide rim for xc duties.

The 41's look massively deep in the section, would be very stiff.... Maybe too stiff* (One of the complaints about about the 1st gen ENVE wheels)
* I have no personal experience with carbon MTB wheels, so could very well be talking out my arse.

Suggest you do a search for "Derby Rims", which are the rims Ibis based theirs on (they're mates with Derby apparently and foot some of the bill for his rims). Very good reports by all accounts; I've just built a set up but have only had one short ride on them so lot enough to give a serious opinion. They are certainly well made and built up nicely.
If you want something not quite as wide check out the Syntace W35MX's; they're 35mm outside/30mm inside, almost as light as carbon rims, and they're without doubt the tightest factory-built wheels I've ever seen. HUbs are great too, very light, adaptable to various standards, and have a star ratchet freehub.

I can't believe after 11 years that this is your 1st post.:ranger:

These 41mm rims have been 11 years in the making.

Heard great things on them and wonder how they go as a trail bike wheel. Got an email from Derby saying they will have more available in about 3 weeks.
did you get the xc or heavy duty rims?

I got the HD rims as they're very light either way, and for the sake of a few grams I'd rather go with extra strength. FWIW, I built the 650B's (HD) up with Sapim CX-Rays, alloy nipples, and Syntace MX hubs; 770gm front and 810gm rear is pretty crazy weights for a rim of such girth! A friend of mine also has the same rims but in lightweight layup; he's been riding them for about 2 months and things seem to be going pretty well so far...

Yea think I would go HD too.
One thing that I have trouble getting my head around with these wide rims is the physics of having these big bulky looking wheels. By the looks of them to me I feel they would be sluggish and slow on flatter trails and with the lower pressure wouldn't roll as fast.
On the other hand they are lightweight and very rigid so apparently transfer the power well.
Will be interesting to see how these go as trail bike wheels, copping with downhill, uphill and flat trails or if they are more suitable for endure/gravity riding.

I am testing these wheels at the moment. Only done 4 rides, but a few initial comments...
- You must use round profile tires; HR2 and Magic Mary don't work. They become way too square and wide.
- Wheel stiffness and acceleration is impressive
- I am 95kg and I can comfortably ride 18psi fr 20psi rr.
- Width + low pressure = great traction and low rolling resistance. and great stability in corners even at low pressure.
- I love the feeling on roots and small bumps with the wide contact patch and low pressure.
I am definitely a wide rim believer now, the handling is fantastic. Can't comment on reliability strength yet though, and just be sure you get appropriate tires!

Read a good review of these on PinkBike yesterday which reflects your comments

Thanks for the meaningful reply Horsey, great to hear someone backing up what the manufactures claim. What tyres did you end up settling for?

Depends on where you ride, unfortunately I don't have a stable of bikes at my disposal, so something that crosses into both categories is what i'm after. I was more interested in feedback on the 928 rims that would be more fitting than the 41mm wide rims.
Interesting article here:

Cheers, I'd like to think that I find myself too busy having fun riding than to be sitting in front of my computer on these forums. Haven't really used this much since I joined in the farkin.net days. Just looking for some meaningful feedback on wide rims.

Haven't been able to test a lot of different tyres. The magic mary simply did not work, HR2 I was advised in advance is also too square. I have been riding with a 2.3 Minion DHF EXO TR on front, and a 2.35 SG Hans Dampf on the back. This combination works really well.
I want to try the minion DHR2, but cant get them. Also want to try some of the continental tires that have very round profiles.
An update to this review...
After 4 weeks the rims have held up to some proper hard core enduro riding in the Swiss/Frenchi alps. Unfortunately though the freehub died, and to be honest from what looks to be just poor quality.
So Rims = Great! Hubs = shit!
I think I am gonna get the rear rim re-built onto a Hope pro 2.

any chance you can upload a pic? curious to see how exactly it failed
