12 SPEED FLAT TOP CHAIN FOR SHIMANO/SRAM

The SUMC 12-Speed Flat-Top-Style Chain aims to meet modern drivetrain demands for riders in India shifting to 12-speed setups on road, gravel or MTB bikes. It targets smooth gear changes, efficient power transfer and reliability in varied Indian terrain — from humid coastal flats to dusty rural roads. Its slim profile and refined plate geometry are designed to engage narrow-spaced 12-speed cassettes, helping maintain cadence and shifting precision even under load. This chain is presented for cyclists who prioritise light rotational mass, responsive pedalling and an upgrade from heavier multi-speed systems. Available now in India at Cobbled Climbs.

SUMC is a drivetrain-parts manufacturer producing chains across 8- to 13-speed configurations. The brand’s philosophy centers on offering broadly compatible, functional drivetrain hardware that balances performance and affordability. SUMC chains serve riders seeking dependable shifting performance across road, gravel and MTB setups under varied conditions — an appealing choice for cost-conscious cyclists aiming for reliability without premium pricing.
