Shimano uses pins while Sram has the link. The local shop adivsed me not to use the Sram link on a Shimano chain. When the time came and I needed to connect a Shimano chain, I had a dificult time locking the Sram link. I should have bought a shimano pin instead. Also, Sram links comes color coded for 10, 9 & 8 speed Sram chains if you need to buty just the link. I believe the Shimano pins also are specific as to 10 or 9/8 speeds. So if you need to buy just the pin, specify what chain you will use it for.J-No said:I'm looking for a simple, no pins, no wierd links, chain for my fixies. They are both forward facing semi horizontal bikes, so I do not have unlimited adjustment.
