Bought this Shimano Tourney FC-TY501 Crankset in 170mm to freshen up an older commuter build and it does the job without any fuss. Installation was straightforward with the usual tools, and the 170mm arm length feels right for my riding position. It's clearly a budget-level groupset part, so don't expect featherweight, but shifting has been reliable on my daily rides. Good value if you're repairing or building a simple bike rather than chasing performance.
