Hi ab all
Short version.
Shouldn't the side of a chainring with the manufacturer's name on it
point outward? My new middle won't fit that way. Am I, or is the ring
being stoopid? (ps: ok, ok, "both" is the obvious answer...)
Long-winded version.
Chain had started regularly skipping on middle chaninring, so I shelled
out for new running gear. And got great service and good price from LBS
BSC, etc etc.
I had a choice between buying a $ 60 or so Blackspire chaninring or a $
32 or so Shimoano one (I only needed to replace the middle one.) The
Blackspire one just had uniform teeth, the Shimoano one had the
differently shaped exit teeth and the usual bumps and lumps... and also
4 steel ramps near 4 out of 5 the bolt-holes. Fine, I thought, there's
$ 30 towards the new Lakes fund.
(I briefly looked for a pic. Closest I could find is this:

.. It's a 9/10 sp 110/74 bcd and mine's 7/8 94/58. It's only got two
ramps, and they're not visible, but you can see the rivets holding them
on on the top ond bottowm of the ring.)
Anyway, the ramps are on the side which has the name. (Also the other
side has the teeth flush with the alu, whereas the side with the ramps
has the alu cut back from the teeth.) I assumed that because of this,
and that the ramps were there to assiist changing from middle to big
ring, this was the side that faced outwards. Except when I tried to put
it on the crank, two of the ramps got in the way of the crank arms (FSA
170s, for my little legs). Fitted fine, but I'm pretty sure I've got
the middle chainring round the wrong way. (ps: I picked the old ring
out of the "to be hard rubbished" bin just to check out what was going
on this time last year... and noticed underneath all the black oily
grunk were steel ramps, facing inwards!!!)
Have I got things ****-around (yet) again?
