Shimano 10 Speed Bosch / Steps 138 Link Chain
This is a Shimano SLX 10 Speed Chain for all 10 speed Bosch / Steps eBikes.
Special for the STEPS system, SHIMANO made a reinforced chain dedicated for E-bike usage.
It is treated with SIL-TEC coating and for front single gear only. Extra long at 138 Links.
SIL-TEC is SHIMANO’s low friction chain surface treatment. Superior to simple coating, SIL-TEC is an advanced plating process that improves system performance through the use of imbedded fluorine particles. SIL-TEC treated products run smoother and wear longer in all conditions.
