Park CT-3 vs. CT-4 chain tool?
Anybody know what the difference is? The Park web site says the CT-4 is "new" and is "specially designed to work with the tight tolerances and narrow profile of 10 speed chains and most high quality derailleur chains." Is there any issue using the CT-3 on 10-speeds? I don't see many vendors carrying the CT-4.
I'm looking for a good all-around shop tool for chain breaking on a variety of 7- through 10-speed road and mountain bikes. I've been using a CT-5 mini-tool which has worked, but the last couple times, it felt like it was going to break before the pin would let loose on an SRAM chain and I want something more substantial for shop use.
