SRAM’s T-Type chain differs from more conventional chains like Shimano 11 speed or KMC 11/12 speed not only with its distinctive flat side. The differences can also be found on the inside of the chain. The most significant of those variations are the smaller distances between the inner and outer link plates and the larger diameter of each chain roller. Even though the distance between the pins of the T-Type chain and the more conventional chains is the same, the larger diameter of each roller on the T-Type chain leaves less space between the rollers.
