Isn't going up teeth in the back "easier" on the bike then the 14T mod?
obviously it is pricier, but figured it was better for the bike.
When the chain crosses a 14t sprocket, a greater 'flex' angle is exerted on the chain as compared to a 15t sprocket with a larger circumference.
A larger rear sprocket also has the benefit of moving the chain marginally further away from the swingarm... so ever less chance for rubbing on the swingarm.
So is it better for the bike? Ehhh... push. Probably better for the chain though.
