We did our homework on this cog and we think you will be pleased with the result! This 16t cog smooths out the cog to cog transition when using our GC and a standard 10 speed 11-36 cassette. You should expect this to shift well and last as long as the rest of your cassette cogs of similar size.
Here are the transitions WITHOUT the 16t cog (4 tooth max jump):
Here are the transitions WITH the 16t cog (3 tooth max jump):
Shimano 10 speed cassettes
Other 11-36t shimano cassettes like SLX HG81 11-36t - Modification required (must drill out rivets holding the 17t to the larger cogs)
SRAM 10 speed cassettes
PG 1030, 1050, and 1070 - 11-36 and 12-36
