Rhythm Section Mini Cruiser 24 x 1-1/8" RimsPRODUCT DETAILS The Rhythm BMX Mini Cruiser 24 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 Cruiser rims come in 3 solid colors and do not have silver side
