LEXON Road Carbon Crankset

[womble73]

Was looking at putting together my lexon crank today with the xcadey power meter. Everything fits into place nicely. But when I hand tighten down the PM spider onto the crank there is about .5 mm to 1mm of play.
IE: I can rattle the PM on the crank. Do people normally put a spacer between the PM and the crank? If so which side of the PM and what size spacer? I would assume the charger side of the PM. It feels important as the side the spacer is on will impact the chain line, not by much but you never know.

I noticed the same. But after I tightened up the lock ring to 30Nm with a torque wrench, the play was gone.

Thank you, I will give it a go tonight and hopefully it solves itself.

Which tool do I need? I have a small one that I use to remove my disc brakes and cassettes. Is that really sufficient? They show on with what seems to be more teeth on their picture. Both are called freewheel remover.

I used an old tool that was originally made for installing and removing square taper and octalink bottom brackets.

Ah that one. Thanks!

Same tool I am using. It is 20 tooth. I had it in the tool box from when I replaced the crank on my 20yr old mtb.

Not to necro, but has anyone else had this issue?

The lexon spindle is advertised as 92mm. It actually measures like 96mm. This is it in a bb92 pressfit BB - it's way too big to get a normal chainline.

Is this a dud?

Hi there,

Does anyone use the new crankset with a bottom bracket Shimano (or equivalent) BBR60 BSA ? If yes, do you use crank spacers and what are the sizes that you use ? I saw a YT video in which the person uses 3mm spacers on the non-drive side.

I always use Shimano crankset with Shimano BB, so it’s pretty new to me.

Thanks for the help !

Ok this thing is legit crap. Do not buy. 

The chainrings are awful, I had the issue of it not fitting, Lexon did nothing to help so I forced them together using the bolts to basically clamp them together, eventually they deformed the surfaces that were too tight to come together.

The bolts are cheap aluminum, they are marked 7075 but I don't trust that at all. They are terribly designed so there is no hex on both sides of the bolt, it is one hex head and the other has these slots, and the outside is knurled for a vise grip, but they instantly deformed when any load was applied, incredibly soft aluminum. I would not trust these bolts at all. The knurled surfaces are all marred. You need an enormous screwdriver to span the distance of the slots, these will quickly get chewed up if you remove them more than a couple times and then removing them will be a nightmare. 



The spindle length is ridiculous and requires over 1cm of spacers for a BB86.



The machining for the threads for the preload collar is terrible and 'facetted' more than actually round. It's very tight to move and feels awful. 

 

The chainring teeth are terribly profiled and suck the chain up in them.

Oof.  This is not good.  I picked the same crank and chainring combo over 11.11 for 240.00 USD.

I haven’t started my build yet but I bought the 24mm version after being pleasantly surprised with the 29mm DUB version from Lexon.  I have a few hundred miles on the Lexon cranks with no issues to report.

I will have to test fit the 24s to my new build and see if I have the same issues you have had.

Why didn't you just send it back?

And with regards to testing the cranks when your build is done: Most of the issues repoman observed can be checked off bike I guess?

Lexon doesn't really respond to messages. I've sent them probably 4-5 messages about the chainrings not fitting the spider and just get 'did you try pressing it together?'  I shouldn't have to put a spare chain on the ring and fiddle with it to see if the chain sticks on it. I shouldn't have to put the bolts in a hardness tester to see if they are junk or not. The stuff should just work out of the box.

I understand. The second part was directed at biceryder

I have a pair of Lexons that work really well.  I will test fit the 24mm cranks with the chainrings and in the BB. If I encounter any issues like repoman, I’ll send them back.  So far, I only took the out of the box for a quick visual inspection. They looked really good to me.
