    New question here. Recommendation for 9-Speed chain with Chainrings without Shift Ramps and Pins ...

    Hi All,

    I will be changing my Chainring configuration as follows for a 104/64mm spider on a Specialitiés Carmina Crank. The rear cogset is 9-Speed 11-34T.

    Inner: Blackspire Chuck Ring 22t (Stainless Steel)
    Middle: Surly 34T (Stainless Steel)
    Outer: Specialitiés Chinook 7075-T6 Al 46T

    Is there any particular chain you would recommend for the above configuration? Will any 9 Speed chain be sufficient? Or are there some that will shift better with chainrings that do not have shift ramps and pins?

    My current configuration uses Race Face Al Chainrings (24-36-48) with an XT 11-34T cogset and a KMC X9 SL Chain. The upshifts (small to large cogs) at the back aren't that smooth nor quiet and I have problems at the front too which I think is due to the bottom bracket axle being too long (122mm). I will also be changing the BB to one that is 118mm.

    I have a similar configuration (no shift ramps and pins) on my old rigid bike which has a 7 Speed cogset (13-34T) and the front shifts very well.

    Thanks, Michael.

    I don't think you'll notice a difference between chains. You can get 34t ramped chainrings though, unless you're really attached to the Surly for some reason? TA, Blackspire and Middleburn at the very least will do a 34t middle ring.

    Non-indexed shifters will shift the best, SRAM gripshifters work too, I've used unramped rings with these. Shimano/SRAM trigger shifters may be hard to set up.

    Hi Joel,

    My old rigid bike uses indexed shifters.

    The reason I want the Surly is because it's Stainless Steel and they can be flipped over to double the lifespan.

    The 36T middle, I currently have, is looking worn.

    Has anyone used an IRD Pro 991 Hollow Pin Chain?

    Thanks, Michael.

    Without ramps or pins, it really isn't going to make that much difference up front, but you still want a durable chain that shifts well then KMC or Shimano (with a Power-Link) are excellent choices.

    I use mid-level SRAM chains.

    Avoid hollow pin chains.

    Hi Jeff,

    My Front Derailleur is a 1994 or 1995 Shimano XTR.

    Why do you ask?

    Thanks, Michael.

    More expensive, more likely to fail.

    I think I read somewhere, once, that later FDs usually cater up to 44T and or there is a tighter limitation regarding the difference in the number of teeth between the inner and outer chainrings.
