SL extender is not compatible with full power Kenevo/Levo. Afaik there is only this 3rd party solution but quite expensive: Trail Watts Booster Battery Systems
If you have base 2020 Turbo Levo you need:
- cassette: SRAM PG-1130
- chain: any SRAM 11-speed will work, I recommend PC-X1, make sure its at least 116 links long
- front chainring: original has a part number S161400009, however any 104 BCD 32T chainring should work, just make sure it is a steel...
No firmware update was mandatory ... I guess you'll have to wait at least a few weeks to get a feedback from first riders if they feel any difference at all ...
Post a photo of those 3 smallest cogs, I bet they are just as they supposed to be, teeth should not look all the same, some look like they are half missing because they act like 'doors' so the chain can more easily jump between cogs when you are shifting gears ...
I bought new shock Fox Float X for my Levo, now I have to buy a mounting kit, I found out that Fox has 2 mounting kits with 6x20mm size:
- 5-piece with part number 803-03-244
- 7-piece with part number 803-03-327
So which one is the right one for my shock + Levo?
Edit: I believe I found out...
SL (Mahle) motors don't have a belt transmission (what makes them much louder) and their torque is only about 1/3 of Brose, so not really comparable ...
