Hudud carbon cranks

[GRYaris]

Hi everyone, this is my first post. I bought a Hudud crankset, which is very nice, but also very problematic. The titanium shaft has a tolerance that, in my opinion, is incorrect, because the diameter of the Cema bearing housing measures 24 mm +/- 0, while the shaft  has an outside diameter of 24 mm -0.01 mm. Clearly, with a tolerance of just one hundredth, the shaft won't fit and with grease, things get complicated, there's no way to insert it. Has this happened to anyone else, or is it just my problem? Thanks, I look forward to your replies.

Once my grx cranks were so tight to install I ended up sanding my bottom bracket a bit. Didn't take much as it had plastic on top of the bearing. It's not ideal of course. Or maybe try another bottom bracket or then just return the cranks.

Thanks for your reply. the fact is that the Cema bottom bracket works on the inner rail of the bearing and has no plastic to grind . The fact is that the Shimano crankset fits perfectly, so the movement has nothing, it's the wrong titanium shaft. I feel if I can get a new shaft sent to me

I just installed mine on my road bike with no issues at all apart from sorting out which spacers to use. Long 5 hour ride on the weekend with 1600m elevation and over 130km and the crankset performed nicely. Finish is also very nice and in my 165mm weight was spot on at 180g (verified with standard weights). With the spacers add a few more grams or so. 
I'm probably going to get another set in 160mm for my TT bike.
Note I had to modify my Megene Power Meter spider to fit the Easton spindle but that also worked very well with no issues with performance. I'll post a full seperate review after a further test ride.

I have the same issue with magene powermeter. How do you fix the fitting ? Do you dremel (or file) the dent on magene powermeter to fit the easton ?

I know one person who has used a dremel but I think you could destroy the power meter/spider if you're not careful.
I used a vernia and a small round and square file. The aluminium is very soft so I carefully shaped it and took maybe an hour as I didn't want to stuff things up.
I'll post a DIY soon when I get a chance. The modification actually fits more snug than the original Megene crankset which was a bit loose. My power readings the other day over a 5 hour ride and 1600m of elevation seemed very accurate and comparable to prior readings so I'd say there is no affect on performance but I'll do another big ride this weekend to confirm.

Thanks Don, excellent craftmanship!!
I'm not so accurate so I switch to a new Coospo S10 and yesterday I fit in the bike

Does anyone know or can measure the crank bolt and extractor cap thread size, is it the same as sram dub? (M18/M30)

how do you use the spacer?
I put the bigger one on drive side.
Today, during a ride, looking the drivetrain from the saddle i noticed that maybe is not well centered in the frame.

Flip the bike over. Find the center on the BB and then play with spacers so that the cranks are same distance from the center. ITs not one size fits all.

You can also put some spacers/washers on one of the pedals to compensate if you want to get things perfect.
For me I I think I put maybe 3mm or so of spacers (2) on the drive side, none on the other side, and 2 washers on the non-drive side pedal.
You can then adjust your cleat position on your shoe for final centering.

In my experience this is a reocurring problem with those titanium axles, diameters are just a touch too large and then interfere with any BB with solid aluminium caps. Using one with plastic caps (e.g. Shimano) usually works fine, though.


My Hudud crankset is unusable because the axle won‘t mount in exactly 90 degrees angle on the drive side, making the chainrings wobble. Down to poor manufacturing of the crankarm insert I assume.

Done, and find a good compromise with 3mm on NDS and 1mm on drive side.

Hey guys, I have this crankset too, but I'm running into a few issues.
First off, the thread on the left pedal is extremely tight; I had to force it a bit to get it threaded all the way in.
Secondly, the crank arms tend to loosen from the titanium spindle quite easily. Has anyone else experienced these problems?

I haven't had these problems with mine. Did you torque the crank bolt to 40NM? Also apply grease to the pedal thread?
Could be that the manufacturing tolerances are out with your set?
