SZZS specific CEF50-main thread (initial builds and troubleshooting related only)

[PaulH]

I can order and send these covers to Europe. But the price of delivery is not small - to Germany is about 50USD(((((

DFW to Almaty via Turkish Airlines is $1,000 and 21 hours. I don't trust courier services

Hi everyone, a little off the topic, has anyone used a fox float X2 on there CEF50? Any issues perhaps?

So, there's two frame versions: 1) the initial no coil or V1, and 2) the coil + V2 frame.

The X2 should work with the latter coil + version. I really want to try the new upgraded RS Vivid, but I have V1 so .

Actually, I think some people here tried unsuccessfully the X2 and Kitsuma DB fitment on V1 no coil. Just not enough room for the bigger bottom air can apparently. Unless I'm misremembering. Feel free to chime in if I'm incorrect peeps.

Looking at my V2 theres definitely room for coils or large air can shocks like the x2, but one thing i am noticing is the leverage ratio and rate is definitely not optimized. I wonder if the V1 was optimized but then they did a v2 just shifting the lower mount hole to physically fit a larger shock without redoing the analysis for the suspension rate. It does not seem very linear and if anything has some weird characteristics where it blows through its travel like it is an extreme rising rate for 75% of its travel then has a falling rate for its last 10%. Imo a coil would not work well at all with this frame because of this and i am having a hard time dialing in my float x.

That's not too bad. But keep field testing it out.

Can you hit it with a rubber mallet (soft and medium intensity) while mounted on your frame?

And before mounting the guard then twist it with your opposite hands back and forth to test torsional strength.

My SZZS guard broke when I tried these methods.

However, with my carbon overlay workaround, I was able to use these methods to get basic strength predictability....then just riding over time to verify its rigor.

I'll give it a try, but I'm not sure I'm ready to hit it hard after your story)))))

i recently update my 48V firmware from CRX30PC4812E102006.1_230216 to CRX30PC4812E102012.1_240412. It has huge different during climb. Previously motor will continue run for few second when my crank stop or leg on ground BUT now motor will stop once my crank stop spinning.

This seems to be a more correct algorithm. Could you tell me how to update the firmware? Is there a possibility to backup the old version - to return if something goes wrong?

you need BESST tool to manual update it. i have several version of 48V firmware. you can not backup it. Firmware 48V – Google Drive

Regarding the Fox X2-Shock: Fits in perfectly...

As you can see in the next picture, I am also running a Shimano XT 12x Cassette with a SRAM GX AXS derailleur.
I do have some very minor issues in the middle-gears, but this does not bother me at all.
Good thing about the Shimano-Cassettes: you can change the smaller sprockets seperately, which are the most used ones - saves a ton of money...

depend where you ride, for me it's the bigger sprockets who are used more

Yeah, you're absolutely right...
To be honest - due to spare-time-issues - i mostly use my bike for commuting etc.
Not really the intended use at the moment.

Is it possible to update the firmware via Bafang Go+?

Is it possible to update the firmware via Bafang Go+?

Yes u can but u have ro be VERY careful , my Go+ automatically update to 36V but my battery is 48V. Once u get the wrong update , u will get an error msg and then u need Besst to fix it.

When u click on update on Go+ , it will show the new update file, look at the file name carefully CRX30PC4812E102006.1_230216.bin this is 48v ...PC48...if u see PC36 or PC42 , it's 36 or 42v.

But do you have a 36V Motor?

My motor it's original 36v which has been covered to 48v.

So the Go+ App detects the motor as an 36V and tries to overwrite the 48V-FW with a 36V?

Yes...that how I end up buying besst to solve my problem.

 

[92se-r]

What is the max power you see with 36v motors? I usually see max of roughly 600w on my 48v

Looks good! So, is your X2 on the Vi frame (air) or V2 frame (coil +)?

 

[Stephen B]

That must be a V2 frame, I still have the X2 that wouldn't fit my V1 frame.

Yipes! Can you sell it?

 

[Stephen B]

Yes, I just haven't tried to yet, anyone want to buy a Fox X2?

210 x 50? New or used? Year? Price?

 

[Stephen B]

I think its a 55 (have to confirm) I bought it used was a new take off the guy replaced it with a X2 coil shock.
I would like to get $350

 

[calvintys]

Why not you replace your front triangle alone , it shouldn't be expensive. I think same or less then ur x2 price.

 

[un..inc]

Yep, should be a V2 frame...

 

[Adilka]

Hi! Is cane creek double barrel kitsuma air will fit the frame?

If your frame its V2 confirm fit , V1 dont know

 

[Adilka]

Asked Jean - they send me v1 frame

 

[Adilka]

Hope kitsuma is smaller than X2

 

[calvintys]

Asked Jean - they send me v1 frame

why u buy from Jean? i have share linda contact here several time. If linda she will ask you for selection.
