Sorry, it took more than 15 minutes, had to finish dinner. Is it fixed?
So far I am the only person to reply that has any experience with or even touched a Sora equiped bike. (Unless I missed one)
So every other opinion is moot.
However, I do think the bike should work better than it does. check the der angle and height.
The previous post mentioned Spec have some triple experience. I am here to tell you the Sequoias are tought to get minimal rub in. Crappy chainline.
