Might work on a mini, but the reach is too short for regular BMX. Probably for road bike.

Minis and Juniors use "road" brakes. On the other hand, the BMX version of the 890 is just an extra-long-reach road brake, 630 and 890 having the same design. And it's Weinmann's design, Dia-Compe licensed it (so that makes Weinmann real and DC fake?)

Anyway, 730 is the size you use in place of 1020, when switching from 1.75 to 1 3/8 wheels. So 630 would probably be the size to use in place of an 890, when making the same switch.

If your bike can use 890's with wide rims, go ahead and switch to narrow rims. You'll get to use your brake that way, and it's actually the right way to use that brake in BMX.  Nobody will flame you for it smile
