Comes in a bundle, a need for the HG-x Folk.
Case your new to bicycle components...HG-X is A Chain Shimano designed for running gear (or group set), so the length of the bicycle may be reliable according & provividing bicycle is...well...kept.
Just what I needed. The chain rings needed to be removed and they were really on tight. It must have been some sort of permanent thread locker. I destroyed the chain ring bolts trying to remove them but it was the crank I was after anyway for use with a Gates CDX chain ring replacement and a 104 BCD.
