Taking SCARY out of used bikes, one bike at a time.

When I was cleaning this chain off of bike I was refurbishing and notice something not right. Oh’ it’s a 9 speed chain that was on a 10 speed drivetrain. Well this was defiantly some oversight on the old owner.
The result of having the wrong speed chain would cause shifting issues, damage or uneven wear. So when looking at used bikes or just bought a used one, double check the chain for matching speed. All chains will have a stamp on the outside indicating what model it is that you can google the speed.(Exp: PC-951 is a 9 speed chain)
This bike got a new 10 Sram (PC-1051) chain and shifts like a dream.
