As the title would suggest I was wondering what the difference was between the SRAM PC-89 and PC-99 hollowpin chains were. One is supposedly a road chain and one an MTB chain according the the SRAM site but I can't see any reason why a PC-89 couldn't be used on a mountain bike and and a PC-99 on a road bike. Are the plates different? Is there any variation in materails used? Would anyone care to enlighten me on this? Thanks in advance.
Actually, there is a difference between the PC 89's... there is the PC-89R and the PC-89 Hollow Pin... which as you can guess has a hollow pin. The 89 Hollow Pin is also listed at 6.2mm wide, which would work with road bike 10 speed drivetrains. The 89R and 99 are listed at 6.9mm wide and the 99 hollow pin is listed at 6.4mm. The width difference is really just because the pins don't stick out as far from the plates on the hollow pin models.
Between the 89R and 99, the only difference is that the 89R has a small cut out in the outer plates so the total chain is like 7 grams lighter.
Here's some pics of the two....
The 89R first, then the 99
