24" wheels, 150mm cranks. My son is 4'8".
Bit of an experiment, but I'm hoping to convert my lad's bike to a one-by system. I already have a microshift Advent derailleur, cassette and shifter, plus a 104bcd narrow-wide chainring.
Unfortunately, I made the mistake of not inspecting the crankset closely enough: What appear to be hex bolts are in fact fancy rivets. I've also managed to completely strip the threads of the square taper arm on the drive side.
So I'm looking for some advice / sounding board.
It's past the 14 day return window to send the items back, and I still want to make this work. Plus he's pretty stoked on the upgrade.
I'm resigned to grinding the drive-side crank off; there's no real way around that, and I can't use them anyway (that I'm aware of...). The question now is how to get something on the front to replace it. I have a powerspline BB and SX Eagle crank arms, but they're 170mm - maybe a little too long. I also have a Deore hollowtech BB/crankset, but again 170mm.
So unless someone knows of a relatively cheap set of square-taper cranks, 104 bcd and less than 170mm, it's looking like the powerspline will be the way we go and simply have to put up with the longer arms and hope he grows fast!
Am I missing anything in this?
