    34 T Chainring question

    Does anyone make a 34T chainring that has shift ramps so it could be used in a 34/22 2 X 10 set up? Seems like all I can find are rings for 1 X 10 appications

    34 T Chainring question

    I ran a Middleburn 34 tooth with no problem. I was running a 24 tooth granny though. I think the Blackspire might even be better though. Seems like it has better ramps. I'm now running one(Blackspire) in 36 tooth. Race Face is good too.

    You do not need shift ramps. Straight cut teeth (not the wide/narrow versions) shift fine and reduce chain drop.

    None of my bikes have ramped rings:
    36/24
    34/24 (2 bikes)
    32/22
    44/30
    54/40/32

    All shift fine.

    The trouble with common sense is it is no longer common

    Shiggy, do you use friction shifters with these setups?

    I have straight cut teeth on several vintage triples with rapidfire, they shift just fine if the front derailleur is set up right. That said , the Shimano sets with ramps are faster.

    IME ramped rings shift faster once the shift has started. But they shift only at the ramps.

    Shifts with straight cut rings can start at any point and complete almost as quickly.

    Not sure about the shift ramps but my E13 crank is 34/24.
    A bicycle will take you to fantastic places....if you let it.
