LEXON Road Carbon Crankset

[biceryder]

Final verdict on the 24mm spindle Lexon cranks.  Super nice, look good, well boxed.  Been riding them since DEC.  I have had non-stop issues with chainring occilation.  At first it was pretty bad.  Narrowed it down to an out of spec spider.  Replaced the spider and Ryet chainrings with Stone spider and chainrings.  Dramatically reduced the chainring rub on the FD.  Lexon’s spiders are out of spec and so tight fitting that I think they flex chainrings ever so slightly.

Fixed all of these issues back in FEB.  Still getting a very, very slight chainring drag on the FD every 12 - 3 o’clock stroke on the drive side.  Finally, I caved and ordered a set of Elilee 310s.  First time with Elilee. Very impressed.  Just did a quick 50km, the Elilees are way stiffer and there is zero chainring oscillation or drag on the FD. 

My personal opinion is that the Lexon cranks are a bit flexy.  Based on issues others have pointed I don’t recommend these.

Thanks.
I just took the chance to order one from carbonbikekits. 

* 165 mm
* 24 mm axle
* spider 4x110 mm BCD

I am about to replace my Dura-Ace 172.5 mm cranks with it. Will keep the DA chainrings.
Just need to decide later on, whether I‘ll go for a spider PM or (new) Assioma.

Do you have any feedback so far? It is tempting to get this particular crankset as CBK allows for choice in spider interface.

24mm axle and 3-bolt interface. I have a really good power meter spider and this could be the cheapest option to get PM to my new BB86 frame. Anyone has any experience with them or other Bigrock parts?

This crankset supposedly has a q-factor of 145mm. So far I haven't ordered chinese cranksets because for some reason they have wide q-factor, but I might have a go with these.

Pros:
The cranks do look good (decent decals, nothing like Elilee).
They’re of good quality.
Weight has been spot-on.
They come well packed in a cardboard box.

Cons:
No instructions.
My 4x110 spider is not true - wobbling Dura-Ace (straight with Dura-Ace cranks) chainrings ain‘t pretty.
Support never answered any of my mails.
Took about 7-8 weeks to get delivered. Shipping was lightning-fast though.


Actually, I am running them with a Sigeyi Spider PM for Easton. This way the wobbling chain rings are nearly cured.

The installation instructions for all these cranks are basically the same from what i can see.
I just received a set of DFS Carbon cranks yesterday, and they look great—24mm titanium axle, 320g for 165mm. Everything seems good, but again, no installation instructions.

I reached out to the company, and they replied saying there are no special requirements, just use standard installation tools. Since there was no manual, I pushed a bit further, and after checking with their "tech team", they sent me some photos. The instructions they provided were basically the same as Cybrei's. I called them out on this, as I had already sent them the link for these 

I pointed out that it’s not acceptable to ship a product without proper instructions, especially since I can't install it without them. I’ll be installing these on a BSA bottom bracket, and according to the Cybrei chart, if the bottom bracket shell measures 90.5mm (as specified), I need to add a 0.5mm spacer to the drive side. If it measures wider than 91.3mm, no spacers are needed, but it can’t exceed 91.6mm. So, if there's any paint overspray on the BB, I’ll likely need to get the shell faced, oh and get some vernier callipers as well.

No instructions are definitely a downside, but my Cybrei crankset cost $500 USD, and this DFS set was only $250 USD, so it's not much of a surprise.

Wonder what you’ll say how these are compared to the cybrei.

I actually don’t have a huge issue with the lexons. Except the chainarm bolt is probably (as previously) mentioned too flimsy. My hex bolt already slipped and damaged the structure a bit. So I think I may buy preventively a new bolt. Anyone has any recommendations?

There does not seem to be much difference when you do a side by side but they are a slightly different shape but only noticeable up close.
Have to wait for my frame from Tan Tan so maybe at least 4-6 weeks until i can install and ride them.

How did you pay 250, their Webshop lists 369, did they increase the price ?

[hagerd]

I've picked these cranks up but got the aluminum DUB axle, we will see if this help with this flexibility issue.

I purchase multiple items from them, including a Wheelset so some discount.
Also i paid by bank transfer more favourable exchange rate and no charges like PayPal.

Flexibility where?
I don’t see how these cranks can flex myself flex is normally through the bottom bracket area of the bike as you pedal.
What bike frame have you got?

[hagerd]

This is just based on biceryder's comments. Im putting these on a ostro vam replica.
