Manufacturer: Praxis
Model: 104BCD PRAXIS 36T Steel 'Wave' Chain Ring & Chain Guide Adaptor for 2019 -20 Specialised Turbo Levo

Description: PRAXIS direct threaded 36Tooth steel ebike specific 4130 grade steel chain ring with Wave™ Tech (Model 104BCD). 10, 11 & 12 Speed compatible. This chain ring has threaded mount holes so you can use your existing threaded studs to fix.

I used it just once on an easy 10 mile ride so there is no discernible wear, other than the black oxide coating having worn away on some of the teeth. Will be shipped in the original packaging and fitting instructions.

These would appear to mount and run backwards on a Levo. Definitely fits a shimano motor correctly, maybe others as well. Just FYI to any potential buyer

ok thats good. one of the guys who fitted one to a Levo mentioned they found that the raised locating bits were on the wrong side for it to mesh and fitted it facing inwards. If you have gotten it to work than it shouldn't be a problem :)

Yes the raised rings round the thread are on the wrong side for the Spesh bikes, but the bolts are self aligning anyway so it still lines up.

The early versions were Narrow Wide, so you could in theory mount it back to front, the newer ones are "wave", so can only be mounted one way or the teeth will be facing the wrong way.

Is mine facing the wrong way Zimmer?

I thought it was right because the bolts fitted

Nope, yours is perfect ?

If you feel behind the ring, you,LL feel a tiny raised ring around each bolt hole. These normally centre the ring on things like Shimanos where the ring sits on the outside. In the spesh bikes the bolts auto center so it doesn't matter.
