The Rhythm BMX Mini 20 x 1-1/8" rim is a double-walled racing rim made from 6061-T6 aluminum with a pinned seam and large hollow internal chamber to save weight.  Rhythm Mini rims are slightly thinner than most other rims in this category as this allows 1" and 1-1/8" tires to fit properly giving the tire that thin profile which means less rolling resistance!

Rhythm rims are solid in color and do not have a silver side walls (except for the white rim which does have silver side walls).  All rims are machined on the brake surface to make the brakes work properly.
