chain kit which includes:
- 18-tooth sprocket (JT Sprokets) in hardened chrome molybdenum steel
- 43-tooth sprocket (JT Sprokets) in high carbon steel
- 104-link RK 525XSO x-ring chain, pitch 525
The chain used in the kit is part of the new XSO series, the best value for money chain produced by RK. It uses X-Ring technology, the best technology available for drive chains. The lubricating grease is in fact retained by twisting and not by crushing, resulting in a lower drag resistance or greater smoothness and less power dispersion and a longer life of the chain over time.
Chain is delivered open with a link to be retorted.
N.B. The chain with pitch 525 goes well up to frame 694351, please check.
