I'm mounting up some TA Specialites Alize chainrings to my Zinn custom 205mm crank and I don't know the proper way to mount the chainrings.
The crank is 130bcd so there are five chainring bolts.
In looking at the outer 46t ring it has four little pins that pick up the chain to help it shift. I can't figure out the right way to orient the chainring on the crank so that these pins are properly positioned during the pedal stroke. On the outward face of the TA Specialites rings there is a little "triangle" or "pyramid" is this to aid in setting up the orientation of the rings? There are two "dead spots" on the ring, they are directly across from one another.
On the middle 38t ring it has four ramps with pins to pick up the chain and unlike the outer ring, there is only one "dead spot" on the chainring. Between any two bolt holes there is a ramp/pin, but the best way to describe the distribution is to say that the four ramps/pins are distributed across 23 teeth of the 38t ring.
How do you orient these chainrings to maximize shifting performance.
Peter White's website, which sells the rings is silent about mounting 'em.
Clearly its not any which way works equally well considering that the pins or ramps and pins are not symmetrically distributed.
