- 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 come in solid colors and do not have 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.
