Drivetrain issues

Evenin' All,

I'm having issues with my drivetrain. the chain doesn't seem to sit on the chainrings properly. It only sits nicely in the teeth fro 1 o'clock to the 4 o'clock position. Also, When i'm in a high gear, it feels like I'm pedaling a ratchet. The shifting is fine and it is the standard set-up 50/34 with a 26-12 cassette (8 spd) from when brought new. It is a Giant Defy 4 2011 Compact. I have changed the rear cassette to a different ratio 23-12 which only increased the issue of pedaling ratchets in the higher gears!

Any advice please.

  • Had the same on my defy 2 - a new chain seemed to fix it.

    Thanks, I thought it was the chain as it doesn't sit right on either the 50 or the 34 and it sits fine on the cassette regardless of which ratio I have fitted!

    Yep, it sure was the chain. Fitted a new one and I'm now pedalling smooth circles! Oooosch!!!!!
