Maybe that final drive was all silver originally but
I expect someone painted it like that at some time.
Not me
I built this bike from a pile of left over CX parts I amassed over the years and that
drive was probably the best looking at the time so it went on.
On a related note, when fitting the rear wheel
I always slacken the 3 nuts holding the drive off bit and fit the wheel and tighten
the axle nut before doing them up again.
I heard this helps the drive splines mesh properly and not bind and wear on one side
which could cause excessive wear and early failure.
It sounded feasible so I do it.
Related note 2:
after I get the wheel on and I fit the collar to the spindle and get it through the hub
I use a spanner on the flats of the spindle and tighten the nut before touching the
clamp on the LH leg.
Note the end of the spindle is almost flush with the clamp on the LH leg.
I've seen a few CX's where PO left almost an inch poking out and dragged the leg in
when tightening the main nut.
This can make removing the wheel a struggle.
If the spindles a bit tight, use a block of wood or something to keep the leg from
getting pulled in as you gently tap it home.
Not trying to teach folk to suck eggs or anything
If you already knew all that, please ignore.
Gene,
Yep we still do many things ass backwards over here
