Thank you. So does the the 21-4 use a 25.8 bearing? I was confused because when I searched 'keep off bearing' under amain a tko 14x28 comes up for 21-4
As far as I know the only difference between the BTT and the Keep Off 4-ports is the bearing size and therefore slight difference in crank case. Other than that all the parts numbers appear to be the same. |

Yeah we need to separate our apples from our pears here, 21-4BTT uses a 25.8 but I think the Keep Off uses a 26mm bearing where Nova has it patented and it seems to be impossible to buy it anywhere unless you buy the Nova bearing which costs like one million dollars a piece.

I'm referring to only keep off 21-4. This link from absolute has a 25.8 for the keep off 21-4 i believe. At least that's whats written on the bearing in pic. Just confused why amain has a 14x28 listed for keep off 21-4.

The keep off uses the same size bearing, in terms of diameter, its the internet race that's different in terms of width. The internal race is 4mm
Edit: some googling later and it says: 14x25,8x6mm vs 14x25,8x5,7mm So 0.3mm difference in the bearing size. |
is there a way to know the factory needle settings of a +4 BTT?
|
Thanks for the help on the bearings guys
