Specially cleaned and low friction treated new Shimano chain (HG-701) packed with a tube of AdrenoTT for easy followup maintenance.

The HG-701 Chain is our favorite race ready chain featuring high strength , good durability and low friction thanks to the Sil-Tec coating.

We de-grease the chain of the factory heavy oil in special bio^degreaser and acetone bath. Then we immerse the chain into a heated bath of our own shop formula paraffin / PTFE plus additives to ensure complete coating and penetration of the Paraffin and PTFE.

Included is the Shimano 'Quick Link' for easy sizing and fitting to your bike.

The AdrenoTT follow-up product lets you keep the chain in top rolling condition without using power sucking oils or other types of lubricants which generally attract dirt and /or do not provide as good friction reduction as the high - penetrative AdrenoTT compounds.
