A chain suited to 50x34 road drivetrains
With its 112 links, this Shimano CN-M8100 chain meets the needs of road set-ups fitted with a 50x34-tooth compact crankset.
This chainring combination offers excellent versatility for road cycling. The 50-tooth chainring aids acceleration on flat sections and during sprints, whilst the 34-tooth chainring makes climbs and steeper gradients easier.
The 112-link chain length is designed to meet the requirements of certain specific set-ups. However, it is essential to check the required length based on the cassette, frame geometry and rear derailleur capacity.
Important: this 112-link version is intended solely for set-ups compatible with a 50x34-tooth configuration. It should not be selected automatically for any other chainring combination.
Shimano Hyperglide+ technology: precision and smoothness
Hyperglide+ technology optimises contact between the chain and the teeth of the drivetrain. It promotes fast, precise and smooth gear changes, even when the cyclist is applying significant pressure to the pedals.
On the road, this smooth performance is particularly noticeable during accelerations, changes in pace and climbs requiring frequent gear changes.
The design of the extended inner plates also improves chain engagement and contributes to excellent drivetrain stability.
SIL-TEC coating to reduce friction
The CN-M8100 Shimano t features a SIL-TEC surface treatment on its inner plates, designed to reduce friction and improve wear resistance.
This technology helps to ensure a quieter and smoother drivetrain, whilst promoting the chain’s longevity when properly maintained.
Quick-Link: simple and secure fitting
This chain comes with an SM-CN910-12 ‘ Shimano ’ quick-link, allowing the chain to be connected easily.
This system simplifies assembly and eliminates the need for traditional riveting. The Quick-Link is designed for single use only and must be replaced after removal.
