JT/JT 420HDR Reinforced Chain Kit 11/48 - Standard Steel Sprocket
Designed for replacing the original transmission with an OEM ratio of 11/48, this JT Drive Chain kit is aimed at urban riding and demanding small-displacement bikes. The 420 pitch chain, in black/steel, is of HDR type and reinforced to withstand daily stresses. The XS-Ring seals ensure good retention of internal lubrication and protection against contamination from dust and splashes.
Ideal for replacing the sprocket and rear sprocket on lightweight machines, this kit is particularly suitable for urban use: daily commutes, city rides, and regular maintenance of your transmission. Manufacturer reference: not provided.
