Derailleur adjustment with compact crank

[Becky]

Instead of doing my Wednesday bike commute I took the tri bike out for a test ride this morning. The good news: no dropped chains! The bad news: I sometimes had trouble getting the chain to go onto the large ring and if I was on the large ring and using the two smallest cogs I had FD chain rub and couldn't trim out to stop it. Obviously I need to move the limit out a tiny bit. Do you think I should do this right away or wait until after my next ride on Saturday? And the stupid question so I can get it right the first time: to move the cage out do I loosen or tighten the limit screw?

Don't touch the limt screw (except maybe a tiny bit looser to improve shifting to the big ring)! One of the limitations of a compact is that, when you're cross-chained small to small, the chain will drag across the teeth of the large ring. Just don't cross-chain and you'll be fine

I can get to about the third cog from the bottom (14T) with the help of the trim before my chain drags on the large ring. I try to shift to the large ring sooner (15T or 17T), depending on cadence and terrain, but the best laid plans....
