    Check this 136 mm q factor crankset

    hey! at last a narrow q- factor outboard crankset
    You know, if you want get things done.....
    Acording to the data the program gives at this point is 620 grams. Arms are not hollow. Axle is steel , arms and rings aluminium. Fixing bolt also aluminium. (bb and bolts not included)
    Its a kind of 960-970 hybrid. Most measurments are by guess (besides BCD and crank arm length, 175)
    You like it?

    Chainline?
    Chainring/stay clearance?
    Arm/stay clearance?
    Are you limited to using 1.5" tires?

    All of the above are higher priority to me than Q-factor.

    I know, I know...
    None of this factors you mention have been considered.
    I was just moving forward for the feel for it. Maybe I draw something more elaborated soon

    5 Arm Please

    4 arm spiders/chainrings are a joke.

    Spindle options for Shimano?

    Hey Shig, wondering if you know of anyone that makes a shorter spindle for Shimano pedals -- don't need Ti, I just want to bring my knees in a bit. I just switched cranks from Stylos to XT760s and it feels weird & slow. Plenty of space between my shoes and the crank arms, so maybe I can run a shorter spindle on my M540s?

    I am the wrong guy to ask. I have no idea and I don't care. Q-factor is a non-issue for me unless it is too narrow. I wear the finish off my crank arms and chainstays with my heels. If anything I want longer pedal spindles.

    Four-arm cranks created problems that did not exist before.
    Less support for the rings and the chainring bolts are more likely to loosen with use. This issue has shown itself many times with singlespeed use. The bolts loosen. One falls out. Half the ring is now totally unsupported and it folds.

    Sure, the bolts can loosen with 5 arms, too, but the ring is still supported enough to just wobble and warn you before it fails.

    It created a new ring "standard" nobody asked for, restricts the possible gearing range and has no advantages other than it may be slightly lighter and slightly cheaper to make.

    +1 for 5 arm 94mm Chainrings.

    Hate that the smallest 104mm is 32. Want that 29 back!

    I put a road triple with one 39T in the outside position. Small Q.
    136 mm would not even clear a road bike. Forget MTB.
