Chris King does not offer a 10mm thru - it was a generally question about the difference between the two.
Shiggy, which would be better then?
The question is! If you have aCK hub already I presume you would be using a QR since you are asking this question if so its would be natural to use fun bolts as
1: you already have the Hub?
2: they will readily fit your rear frame
3: the FBs will stiffen up your rear end as per intended question?
A complete bolt through axle would be stiffer IMO but to acutally benefit from this and feel a difference I think you'd have to be going pretty big on a big ass bike , Ive ridden Hadleys with a 10mm rear axle and CK fun bolts on my Kings and I couldn't tell the difference at the rear when comparing stiffness or strength both have lasted the test of time,
Just for the record, tested on Ellsworth Moment!
However if I was building for a 6inch or above bike again I would used the hadley hub period 108pt eg.
The Kings are nice and I like em below 6inches as a bullet proof light weight sexy Hub.
my 2c
enjoy either way ya go, just make sure the axle will fit ya drop outs if ya go for the latter option.
