After 2000 miles the original chain on my Giant FCR3 has 'stretched' by about 1/16 inch over a 12 inch length. So I'm thinking it is time for a new chain.
The LBS has two chains to choose from. One is a $25 SRAM PC-870 and the other is a $13 KMC Z-72. The original chain was a Z-72. Is the SRAM chain a better chain or should I base my purchase just on price?
