Here is something to ponder when choosing a bicycle chain for our bike.  "A bicycle is only as good as its chain: it is the indispensable link between human power and the bicycle". We agree with this statement 100%, we carry a huge selection of chains for 10 speed, 9 speed and even 8 and 7 speed chains. You can't go wrong with SRAM, Shimano, Campagnolo but we tent to favor the Wippermann Connex Chains.
