new cef55 frame

[jbc]

How does it feel with Air compared to coil previously?

I like how the coil rides better than air but another reason I switched too cause I kept hearing a noise and I thought it was the coil that was causing it.

Does anyone have the progression for the CEF55 frame? I want to compare it to the CEF50 which is 3.7 at 0mm and 2.45 at 150mm (33.78%, really progressive)

There is 5x20mm aluminium bar, mouting holes are about 1mm bigger than steel M6 inserts and are floating a bit for better alignment..
Fiber glass on top and bottom of the battery. All taped up with fiber glass tape + green paper + blue wrap.

Borys, if you find a moment, please send me the hole spacing for the battery. I’m almost done designing the 3D-printed enclosure, and this is the only remaining unknown. Could you also confirm one more thing – is it an M6 thread??
Best regards

Hope this helps, this is for the 700wh 48v battery that fits CEF50/55/69
Total length: 39cm
Space between M6 threads that fit the frame: 2cm
Space within top of battery and first thread: 5.5cm
Space within bottom of batter and last thread: 7.5cm
Distance between two middle holes (the ones that go to attach the frame): 22cm
I'll attach all photos on the next post, this should be enough. IF you need any more info let me know, I have a spare battery here. Also it'd be nice if you can share the 3d printed enclosure afterwards

Replying myself to help with this info:
Leverage ratio: 2.9->2.27 for 165mm rear travel @65mm stroke on CEF69 (22%, works with Air or coil)
2.9->2.33 for 142mm rear travel on CEF55 @55mm stroke (19.6%, ideal for air shock)
