Title: Xiamen Carbon Speed 2025 new carbon crankset
Post by: PeterXu on January 17, 2025, 06:25:24 AM
Sorry, last topic I made seems doesn't work fine. So this is new one.

Attachments are our newest carbon crankset which would be released after Chinese New Year holiday. 165mm size is under testing, 325+/-5g/ set including 29mm DUB 7075 aluminum spindle, 24mm titanium spindle would be availlable as well.

What is the interface to the spider?

If it’s 3 bolt, NICE! I can use my Magene PM. I passed on some frames because of BB86 and lack of carbon cranks with 24mm spindles that had 3 bolt interfaces. Titanium spindle makes that build much more do-able. Still might be interested in the DUB now that I have a T47 frame coming

Easton style. There might be patent problem on 3 bolts design that is why we don't do bolts version.

the spindle-crank interface looks identical to cybrei, the arms are different, so no and yes.

Like the cranks arms actually, there were complaints about clearance issues with the straight arms like elilee and cybrei

Ah yes, I realized looking at it that the preload collar threads are on the spindle vs. on the crank. I sure hope they are swappable though, would be nice to be able to get different lengths for gravel setups etc.

considering the crank-to-arm interfaces are a 1-to-1 Cybrei copy (probably from the same machine shop), I expect there's probably some other Cybrei sauce in there too

I'm super excited for the 24 titanium version. Will be curious to see what spider power meters are compatible.

Currently all my Shimano built bikes run either 29mm DUB/Quarq spindles or Magene PES Base power meters. The Magene probably is most ideal since it's 24mm, but is a bit heavy if you're a weight weenie. And spending $850 on the Cybrei setup is a tall request.

So this will work with the Magene P505 power meter, or am I being daft?  If so, that'd be great.  As Pat said, the P505 is a porker at 800g+.  (170mm & 52/36)

I need to drop some weight from the Magene crank or go to pedal based PM.

No, Magene uses its own proprietary interface for the P505 Base cranks, and does not make an Easton version for the P505 spider. Both XCadey and Sigeyi make power meters to suit the Easton crank interface.

I'm not familiar with the "easton mounting standard".  The Magene P505 PM spider is round and has four mounting bolts, not unlike those pictured in this thread (which are apparently compatible).  raisinberry777 set me straight.  I'm just not that into my p505.  I thought having a PM would be the final frontier, but the p505 added 100g+ to my bike, and the data isn't *that* useful.

Looking for a crank + PM + chainrings for a new build. Would love it to be reasonably light, 165, 167.5 or 170mm cranklenght.

Love ordering via Peter, since I have nothing but good experience with him.

However, I have a few questions:

A lot of ppl seem to wait for:
What is the difference between 24 en 29mm? Why would you rather have 24mm?
For the titanium I guess its stronger or lighter (or both) than alu?

Furthermore, what powermeter (spider) and chainrings would you go for? I love a closed ring and riding 52/36.
Title: Re: Xiamen Carbon Speed 2025 new carbon crankset
Post by: raisinberry777 on February 28, 2025, 02:59:24 AM
The main reason to wait for 24mm is for people with a BB86 frame, since a 29mm DUB crank (made of aluminium) requires the use of smaller bearings. 24mm needs steel or titanium - aluminium has a risk of shearing at those smaller diameters. Weight is roughly the same or slightly in favour of the aluminium cranks normally. If you have any other type of frame you might as well use the 29mm version.

Chinese PM options are XCadey or Sigeyi, they use the Easton interface.

Best Chinese chainring options are Stone or Pass Quest. Lexon is another option.

Since I'm going for a BSA BB frame, I can just as wel go for the 29mm spindle :)

Post by: PoulB88 on February 28, 2025, 04:12:38 AM
For me, the biggest reason to choose 24mm is that with a BSA or BB86 frame, the bearings are very small for DUB and 30mm axles. So You have better durability (of course there is anecdotal evidence suggesting otherwise...) if you stick with a 24mm Shimano standard axle.
Title: Re: Xiamen Carbon Speed 2025 new carbon crankset
Post by: toxin on February 28, 2025, 04:44:57 AM
Bsa bearing are positioned outboard the bb shell. The only thing limiting the bearing size is the bb itself

A lot of ppl seem to wait for:

What is the difference between 24 en 29mm? Why would you rather have 24mm?
For the titanium I guess its stronger or lighter (or both) than alu?

Furthermore, what powermeter (spider) and chainrings would you go for? I love a closed ring and riding 52/36.

Probably repeating what everyone has said, but a 24mm spindle—especially in a BSA bottom bracket—means larger bearings, which naturally last longer.

I have a DUB Cybrei on my SL8, and since I have a press, swapping it is no big deal. Longevity isn't a major concern for me, but I do use steel bearings (SKF/NTN). I previously had a THM Clavicula with their ceramic bottom bracket, and it was terrible—bearings didn’t last, and as a heavier rider, it was noisy as hell when climbing out of the saddle. That was super annoying since I need everything to be completely silent. I ended up selling it and went back to my Dura-Ace crank before getting the Cybrei.

I’m currently running 54/38 MetAero Cybrei rings with an 11-34 cassette, paired with an X-Cadey power meter, which works fine. I’ll be testing this setup in Gran Canaria next week ahead of Mallorca 312 in April. We’ll see if my legs blow up—if they do, I might switch to 52/36 rings.

The bearings typically used for 30mm/29mm/Dub (6806 or 6806-29) and 25mm/24mm (6805 or MR2537) have the same size balls. BB86 is the only standard where you should want a 24mm axle.

There's a mix regarding DUB and BSA bottom brackets. Despite not being limited by size, SRAM still use smaller bearings on BSA bottom brackets. Some other manufacturers like Wheels Mfg use 6806 bearings.

See here:
https://weightweenies.starbike.com/forum/viewtopic.php?t=165166

However, it's also worth considering that loads of major bike brands use either BSA or BB86 frames with SRAM builds and there are seemingly no reports of widespread issues.

Post by: Taicho_Cyclist on March 13, 2025, 11:13:21 AM
I just received the LEESE LSE-C01 carbon crank from Aliexpress which took nearly a week to arrive in Asia. The format is in EASTON DUB as I have the TIME Alpe d'Huez in DUB, making the swap a straight forward affair should I replace the current crankset.

The crankarms are detachable from the DUB axle which made installing of spider or powermeter a breeze. Indeed I have a XCADEY Gen 2-S powermeter spider lying around since the previous LEXON Carbon crank could not install this spider properly. All I took was less than 5 minutes to assemble the powermeter together with the crankset and it was all set to be mounted on the bike. Of course, I do not have a torque wrench to go 40nm but a good yank of the allen key till there is no play is probably going to keep things together.

Total weight is 500 grams flat = crankarms + axle + XCADEY Spider; compare that to a Shimano Ultegra R8100 crankset which weighs 700 grams without chainring and we get a decent 200 grams shaved off.

I have done a short introduction video here - youtu.be/SdwSQCgpMFM  in youtube.

SRAM uses that smaller bearing in the PF30 as well. I have not looked at a t47, but no reason to believe it would be an exception. I believe they use the same bearing across the range. It's a custom bearing you can't buy, so it's very much a one-off.

Dude, relax. Yes, it is helpful to know the weight of the gold standard crankset when considering buying a premium avant garde piece of kit.

wow thanks for the information its exactly what we wanted. none of us knew that the aluminum crank with a steel spindle is heavier than the ultralight carbon crank and we couldn't look it up. Thanks for the info!
I wouldn't worry. 100kg isn't THAT heavy, and i suspect you're not a track sprinter. Don't buy ultra lightweight components, like these cockpits that are pool noodles because they weigh nothing. Ditto, dont get feather weight aluminium cassettes. You'll probably wear out chairings fast if you get chinese ones, but they're cheap.
These carbon cranksets have been around for many, many years, i've had a sram red carbon crankset on my rim brake bike for a million years. As long as there's no manufacturing defect or dumb design (raceworks had a dumb design), you should be fine.

Dude, relax. Yes, it is helpful to know the weight of the gold standard crankset when considering buying a premium avant garde piece of kit.
I wouldn't worry. 100kg isn't THAT heavy, and i suspect you're not a track sprinter. Don't buy ultra lightweight components, like these cockpits that are pool noodles because they weigh nothing. Ditto, dont get feather weight aluminium cassettes. You'll probably wear out chairings fast if you get chinese ones, but they're cheap.
These carbon cranksets have been around for many, many years, i've had a sram red carbon crankset on my rim brake bike for a million years. As long as there's no manufacturing defect or dumb design (raceworks had a dumb design), you should be fine.
