LEXON Road Carbon Crankset

[Shinobi_77]

You are right that having a larger diameter makes the tube stiffer with the same amount of materials. That is one of the reasons why aluminium frames had rather fat tubes.
In fairness to Lexon, all titanium 24mm spindles had this design (flaw) because the milling of the inside of a tube is rather costly compared to the outside milling. (Guessing that the Elilee crank has been milled on the inside)

Weight comparison:
R8100 170mm cranks, no power meter: 555gr
Xcadey 172.5mm cranks with power meter: 592gr
Lexon 167.5mm with Xcadey power meter: 462gr

tried installing the crank yesterday and had mixed experience...

1. the power-meter installation went smooth thanks to the help of the LBS that had right lock ring tool (used for bottom brackets as well)
2. mounting the axel into the left crank arm, no problems. good fit and some wired white paste was already available. still added some grease for good measures
3. mounting the cranks to frame: well this was not going too smooth....
- no spacers where included --> used the spacers from
- the adjustment ring from the left crank arm has an inner diameter of 29mm, this is too big for the spacers which are 28mm OD...
hence all spacers must go on the right side, which is not good for symmetry and might increase the flex (if there is any with my spider legs) ass the right side sticks out more
- the adjustment ring has also a rather short rang compared to the older XCADEY version
- added both spacers on the right side and still have larger gap even with the adjustment ring fully out...
==> not really that well ridable
Now I ordered some more 24mm spacers from Amazon, should arrive today and use this temporarily.
My idea is to use an aluminum head-set spacer (ID 28.6mm, OD33.5mm) to put it on a 24mm crank spacer (OD 28.7mm) via hot/cold shrink or sandpaper followed by GLUE. does anybody has experience with it?

Pics from the spacer and the alignment ring.
It seems that the Elilee X310 24mm has a better ring that goes close to the 24mm axle

Maybe just get rid od the ring and put spacers there. I've done that on my dub cranks in my gravel build, no problem.

Managed to mount the crankset!
Figured that the right side needed much more spacers to create clearance between the lockring and the bottom bracket outer shell.
Once this was done the adjustment ring on the left was sufficient to close the gap and avoid play. The ring sits barely on the inner BB seal, which should be fine.
Lexon staff agreed to put spacers in future deliveries. Some installation instructions would be helpful as well....
Below the new and the old cranks on my Sculptura 9000.
Haven't rode it yet but should be happening later this week.

Anyone used the carbon chainrings that come with the lexon R1 "purple" version?
Wondering about how they handle, flex, durability etc. I much prefer the carbon weave look over the non-purple version.

Got the powermeter now as well, no problem with mounting it, in the end 60 gram more than the spider, so I'm quite content.
