ye founded , what I meant is that it is not a well sealed engine cover and the contacts seem exposed to me. however great bike, I'm mounting the whole hope braking system
It is similar tot he arnagment on the e8000 motor - what a lot of us did is put motor foam in there to prevent debris collecting, and also put some electrical/gorilla tape or similar over the top lip of where the cover meets the motor.

Another essential on the way to Spain, ordered 7th of September

For those of you who are close to the limit between L and XL, can you please let us know height, inseam and size chosen?
My case, 6'2" and 35" size L

For those that have gotten their Meta Powers, how annoying and noticeable is the rattle. Its the only thing holding me back from pulling the trigger and ordering one.

Not Commencal, but a good example of EP8 rattle (scroll to 8 minute mark):
With my bike it's about the same, I can make a quick video.

Please make the test with the highest gear and the lowest gear. Chain vibration above the chainstay causes the rattle. It could rattle far less if the chain is on the smallest cog, since it almost lays on the chainstay.

The rattle is from inside the motor, not chain slap.

It's not chain slap. the chain vibrates and transfers the vibration to the chain ring. That's what causes the rattle. If you hold the chainring while you drop the back wheel, there should be no rattling.

I understand it's not like there's a loose ball bearing just bouncing around inside motor assembly :) But in real world, you feet will be on the pedals, constantly loading and unloading clutch mechanism, right?

size L signature, Halloween is over so I peeled off the orange fox float x2 & fox 38 decals which imo looks way better.

I have a 34" inseam & ~80mm of seatpost base showing, I think I'll want a longer dropper than the 175mm oem as I'm still teetering a bit on full down mode, haven't trail tested yet. fox has a 200mm transfer dropper now which has a 320mm max insertion vs frame size L max of 280mm, so you'd have 40mm of base showing which would work for me. oneup or PNW might be even better ie could get them even lower without hitting max insertion limit, I haven't researched yet.

I recommend a few crash/brush tragedy mods, especially ziptie the rear brake disc magnet sensor wire to left chainstay to reduce the chance it gets snagged on a branch or such.

similar for the exposed wire between the display & downtube entry point, trying to minimize the chance it gets snagged & torn.

I usually slit/wrap/ziptie a piece of vinyl tubing around the short section of rear derailleur cable housing too which often gets abused.

I put OneUp 210mm - fits perfect, I'm probably same inseam as you.

I just noticed that Fox 38 does not extend fully, even when unweighted - I can pull on lowers and extend it by about extra 10mm. Do you notice the same?, or it's just my fork...

My fox 38 does not do that.

Your assumption is correct for normal bikes, but the freewheel of the motor let the crankarms spin backwards without any chain(-ring) rotation. So your feet apply force to the chainring in only one direction, movement in the other direction is (mainly) caused by chain vibration.

Obvious question but have you tried pulling on the fork until it fully extends and pushing the buttons on the lowers?

If it doesn't work, I'd guess, that your air chambers are not equalizing properly...
You could try apply max. air pressure and cycle trough, maybe it will open the port.

Holy sh*t! The buttons did it, I completely forgot that they added them (I have old 36 on other bike) - not sure how it is related (vacuum sucking it down?). Too bad I already ordered like $100 worth of Fox tools for servicing air spring :D
Thanks @robat !

I see... I just took the chain off the ring, and it does not rattle when you bounce the bike. There's still clunk when you really smack it.
How do you guys lube the chain then, as spinning cranks backward does not move the chain? :unsure:

You're welcome ?
Yeah lubing the chain is tricky at first. There are some devices you can stick between crankarm and chain, so if you spin the crankarms backwards, they also turn the chainring.
Far easier: Shift in your lowest gear (largest cog) and apply the lube while you slowly move the bike backwards (or move it back and forth, so you don't have to walk).

$0 chain jammer: 5mm allen key cut to catch the chainring when it's placed in the crankarm fastening bolt head. just don't forget to take it out!

Love it. Making one now. Does it clear chain guide?
if you cut it short enough.
it gets a bit tight to pull out since it's wedged against the chainring, I usually have to use pliers. wrapping it in red tape isn't a bad idea to encourage removal before riding.

You can also change out the air shaft so that the extra 10mm is actually useable suspension.....lol

On my other bike I have a scorpion bike stand that I can easily toss the bike on to lube the chain. But this one the cranks have that end cap on them so it won’t work.

Will try the allen key trick if I have a spare one to cut.

Here is a good option, but won’t work on our stock chainrings.

My bike is stuck in France with the following info on FedEx :(


Arrivé à l'agence de IBA le 17/11/2020 à 20:35

Does anyone have an idea what this is? I will be calling Commencal as well a bit later

It's a FedEx business partner. I'd guess your bike is in queue to get transported overseas. Don't harass the poor people at commencal, they can't do anything right now anyway.
Just be patient ?
