Cranks for Children?
A friend of mine has a son on a 145 crankset right now, which is great, except that it's also a 53/39, which is not so great.
The son is 11 years old and I'm nervous about the growth plates situated by his knees. Are there any 46/34 145-length crank options on the market right now? |

What about a huge cassette instead and take off the big ring?

Still climbing on a 39.

A 39-36 is a significantly lower gear than a 34-28. Or is the kid already on a wide-range cassette?

You're right. He's on a 26 (!) now. Call child protective services.

If he's on a small wheel bike (I would assume so with such a short crank), the gearing is affected in a big way and may be OK.

That rear derailleur appears to have a fairly long cage. I bet that you could do a 1x setup, 39 x 11 or 12-36, with that derailleur and all you'd need would be a chain, cassette and new chainring bolts. If the kid rides hard a chain guide would be a good idea though!

If the derailleur can handle a cassette with a 30, that will be like an mtb gear on the 24 inch wheel.

These cranks are not exactly what you are looking for in gearing, but closer at 48/36.

get that kid on powercranks. Teach him proper pedaling technique when his brain is still teachable.
