Chain reaction

[Rich Fredette]

My 72, 175 has a old school 530 (chain - 50 SL USA) drivetrain at 11 and 52 and considering about a switch over to 520. Looking for a overall trail/power lines set-up. 13/50...12/52? Recommendations?

Rich, may want to give AL B. a call on that 520 set up.  Last I knew they where not available but that was a while ago. If the 520 is available I would recommend it for lighter weight and more clearance with narrower chains to pick from.

After looking, I believe you may be correct - the 5-3/4" hub may limit the option.
