HELP SECTION
Optimal Speed - the ideal number of rear cogs, based on the outer width of the chain and the cog width it was designed for. For 6 Speed Shimano Uniglide a 5/6 spd chain will perform best.
Shifting System(s) - indexed shifters 'click' when you change gear. For 9 speed upwards (or Suntour Accushift), to guarantee the best performance we recommend using the dedicated chain. Otherwise, for 8 speed and below, or any speed when using friction shifting (non-index), you just need the correct outer width.
Outer width - measured across the rivets at the widest point, these are the approximate widths for different speed setups (up to 4 speed is also dependent on cog width):
Speed | Outer Width |
---|---|
2 to 4 Speed (1/8”) | 8.5 to 9.5 mm |
Up to 6 Speed (3/32”) | 7.8 to 8.0 mm |
7 Speed / ‘Narrow’ 6 Speed | 7.3 mm |
8 Speed / ‘Narrow’ 7 Speed | 7.0 to 7.3 mm |
9 Speed | 6.5 to 6.7 mm |
Cog Width - the gap between the inner plates allows for different rear cog/sprocket widths. 3/32" is the standard for 5 to 8 speed, above that it’s 11/128”. For 4 speed or less, 3/32” and 1/8” were both used, for the latter you will need a 1/8” chain. A wider 3/16" moped chain can be used as a heavy duty opton for single cog setups if required).
Chain pitch - the distance between the rivets/pins. All chains will be 1/2" with two exceptions; 3/16" (“inch pitch”) for very early track bikes, or Shimano's short lived 10 mm pitch system from the 70s/80s.
Number of links - if you're unsure how many you need, measure your old chain (each link has two rivets) or one with a similar setup to yours.
