durability of components first hand.
In the 9-speed vs. 10-speed arena, there are some important
things you should know.
10-speed chains are very thin, as are the 10-speed cogs. This
means that they don’t last near as long as a thicker chain and
cogs. In cases of heavy commuting or touring we’ve seen many
customers who get about 700 to 800 miles out of their chain
and cogs. For some of those customers, that’s about 1 month
of commuting. That’s 12 chains and 12 cog sets per year. For
a customer riding across the United States, that’s 4 chains and
4 cog sets. When used on a tandem, the mileage decreases by
By contrast, these same customers would be getting 1,200 to
1,500 miles on a 9-speed chain and cog set. Does this mean
that an 8-speed chain and cog set would be even more durable?
Yes, but 8-speed shifters are not available in anymore,
so 9-speed shifters are the new durability choice.
