Hey guys,
it seems we donˈt have a thread on the new crankset by ZEROING. Heaps of offers on Aliexpress currently and as far as Iˈm concerned they pretty much look like a copy of the Ingrid crankset.
Really like the looks of them, and Iˈm seriously contemplating in using them on a Neo Retro build I am currently building up. However what sets me off is the 24mm alloy axle and the mounting system that goes with it. Looks pretty much like the Fovno Phantom/Ghost axle and Iˈve heard of the crankbolt shearing off on them. Iˈve also already seen a review from someone who had his crankbolt shearing off on them aswell so I am fearing that this beautiful crankset is suffering from the same problems as the Fovnos.
Has anyone found a trick to make these 24mm alloy axles on chinese cranksets last?

I'm using 3 bikes with 24mm alloy axle spindles (2 carbon, 1 hollow alloy). I'll report back after a few hundred miles/kilometers. I'm wondering if the issue is with improper clamp bolt torque settings? Just ask any of these sellers and they have no clue what the settings are.
-
I have those cranks and that same bolt broke on mine after about 10 miles.
-
I've always been wary of chinese parts or frames that are obvious copies. They tend to have more effort invested in aesthetics than functionality. Nonetheless I almost ordered one of these because they do look really good. Glad I waited a bit.

Yeah after reading up on the Fovno cranksets and other reviews of this crank some more, Ive decided to give these a hard pass aswell. No point in paying a 100 bucks for nice looking cranksets that will fail after a couple of months or even just after 10 miles.
I'm wondering what goes through these manufacturers minds sometimes - it would be really easy for them to fix this problem: simply install a well made steel crank bolt instead of the alloy bolts as they seem to hold about as much torque as swiss cheese.
-
I have 2 of these cranksets. I only ridden 1 ride and other still in box. I put blue threadlocker on but I didn't like how it was wider than my other cranks so not using them. If I ever use them gunna use red thread locker or expoy. If they fail I'll tap and grub screw the basters together.
-
The alloy axle cranksets I've been using are Shimano compatible. Though you still need to use the same pre load crank bolt provided with the crankset. No issues yet, but I do periodically check them.

I'm curious about a detail, is the crankarm bolt hollowtech2 compatible? And what does it take to install? Hex 6mm? 8mm? Some proprietary bs?
-
First thing I thought when I saw the ZEROING cranks is: OMG, how would I ever keep all those little divots clean? They are on the front and back side of the arms. If I can't wipe then down quickly with a cloth No way would I want to have to get out a hose or the pressure washer to clean those hole out
-
I'm confused as to how these are supposed to work. Is the crank bolt on the ds arm not captured below an extraction nut? From the looks of it, there isn't even a proper way to pull the ds crank arm off(?!)
Also, the bolt seems to have suffered from lowish thread engagement, but I might just be misjudging the picture.
-
These crank arms probably require a crank arm extraction tool. They used to be more common before many manufacturers stated installing self extracting arms. ( A top cap where the threaded bolt pulls the arm off as you turn the bolt.)
-
extraction tool
I can't make out a thread for that to grab on in the picture (but it's too blurry). Even so, it seems kind of weird to put one self-extracting arm and one that requires an extractor from when f***ing-pos-I-hope-it-dies-in-a-fire-good-riddance square tapers still were a thing into one and the same crank set ... in 2023 no less.
It's a questionable design choice, is what I'm getting at, I guess.
-
Bumping this one too, as I'm considering buying this setup. Looks like there are multiple from Zeroing, Cruzbike, and other labels. I didn't consider a lack of self extracting bolt....hmmmm

24mm spindle is not a good idea. There is a reason shimano keeps it steel

I have 24mm 7075 alloy axle spindles on all my bikes. I haven't had any issues...yet. The weight savings are very noticeable. All I do is hill climb and go out of saddle quite often. Though I weigh between 68-70kg. I figure at my size, I can get away with a lot of weight weenie hacks that thicc cyclists wouldn't be able to pull off.

What's the realistic weight difference between 24mm steel and alloy spindles? 30, 50, 70 grams? 100 grams?

Depends on the crankset. The Racework carbon crankset is about 377g and the Goldix/Zeroing crankset w/hollowed out crank arms is about 475-480g. In order to match those weights, you have to go Dura Ace of SRAM Red at a significantly higher cost.

Comparing the Senicx PR2 and PR3 cranks (the only difference seems to be that the PR3 has a 24mm steel spindle, PR2 has a mm DUB alloy spindle) the difference is about 70-80 grams.

I did some digging, found weight for non-Shimano spindles - 160g for steel, 90mm for alloy. 70 grams savings is less than 0.1% of total system weight (typical accuracy of digital scales is 0.1%). Comprimising the durability of one of the highest stress areas for literally meaningless gains is not what I'd recommend.

The alloy spindle axle 7075 T6 cranksets I received all have manufacturing date stamps, so at least I can keep track of their wear life. They've all held up just fine. Plus I rotate my bike usage to reduce component wear and keep on top of my regular bike maintenance.
-
I think an aluminum spindle is fine in the right application. Mine would be going on a TT bike which will rarely see loads over 1000w, and minimal mileage all things considered. I wouldn't use one on a mountain bike or sprinter bike, but even that might be fine with a light rider.
-
I’m bringing this thread back because I’m eyeing these cranks for the 11/11 sale. Does anyone have long term experience with these 24mm Aluminium axles? Have the issues with these been ironed out? I’m thinking of using these with BB30 bearings and use a delrin sleeve to save the aluminium axle from the inevitable wear marks that steel bearings would otherwise cause.
I’m no flyweight though. Around 82kg. So I’m a bit worried they might not last.
-
I think they're ok - no issues over the last 6 months. You definitely don't want to over-tighten those bolts.
They feel like both the self-extracting bolts and the axle were made out of some regular Al alloy - I had to grease several times to tighten them without squeaking.
Having said all that, I took them off my bike (200lbs) and gave them to one of my kids (80).
YMMV.

Did they feel stiff enough to you?
-
I had just ordered one of the Evosid branded ones, but it looks virtually identical. Does anyone have any experience with these?
-

they were stiff enough for faffing about, but I would not race cx on them. they flexed but not an alarming amount. if you are concerned about flex, just get CF tbh.
-
I was a bit panicked by this post as I just bought Cruz bike crankset. It looks the same but the axle is steel (I just checked). The weight is the same as Shimano 105 and they came in shorter sizes as I wanted my sister to get something works better for her than 170's.
-
I have received my Evosid branded crank that looks nearly identical.
I had trouble mounting it because the pre-load collar lock screw was too short and ended up stripping the threads out of its hole. I took it to a hardware store to see if I could find a replacement, it was an M3 x 5mm torx screw. In the hole it had maybe 2-3mm of thread engagement, but there were probably 5mm more hole to fill. My goal was to find a longer screw and hope that the additional 5mm or so of threaded hole had enough thread to not strip out.
I found plenty of M3 hardware, but no torx head bolts. The socket head cap screw I tried stripped the head, thankfully I was still able to remove it. I found a phillips head M3 bolt, but I couldn't get enough torque on it to tighten and then the phillips head started to give way so I left it as is for now. I ordered some M3 x 10mm torx head bolts on amazon and I should receive them today, however I just discovered that the chainring I bought doesn't fit my chain for some reason. So... now I have to wait ~10days or so for a new chainring before I try again. I'll be pretty disappointed if I get this new chainring and torx screw and find that the lockscrew threads strip out even with the additional length of screw. I should still be able to make it work, though, with a nut on the other side of the collar.
