KMC 1/8" half-link
$3.50
This extremely handy little link will add or subtract 1/2 a link (1/2") from your chain, allowing you to move the axle 1/4" forward or backward to dial in chain tension or slam that rear wheel.
• for use with 1/8" chains only
• available in two versions - black works with all standard KMC chains (and most others), nickel plated works with K710 and K710-SL chains
