Chain Catcher for outside "big ring"

I have my bike all setup with barcons and it shifts great. Every so often when i go from my middle ring up to my big it will over shoot and throw the chain. THe adjustment looks right and once the chain lands on the big ring correctly it doesnt want to go further usually. I cant figure it out.

Do they make a "chain catcher" for the outside ring? I know they make them for the inside. It is very frustrating to throw the chain on a fully loaded bike. Or......does anyone have any tips on this area?

Bring the outer limit in by very tiny increments until the problem is resolved.

Is your big ring bent (warped)? That could possibly be an issue.

+1 That is absolutely the correct thing to do. The emphasis on "tiny" (say 1/8 of a turn or less) increments is important.

Another approach is to bring the outer limit in until shifting to the big ring becomes difficult. Then back it out by degrees until shifting is smooth and crisp again.

Both achieve the same objective of setting the limit such that it prevents over shifting, while not interfering with shifting in any way.

ah....thats a great idea. I have a old KOOKA bashguard around here somewhere that i can try. I did futz with the limit screws a bit and that did help. I am very mindful when i throw it back up into the big gear which also helps. I run in the big gear most of the time and the 2 smaller are for hills so it isnt very often where i am changing.

I am going to dig out that bashguard.

Here it is just back from the Maiden Voyage after getting it built up. I loaded it down with all my gear for a test run. I dont have front bags yet but i had plenty of weight on it. (Tent, bag, pad, misc locks and tools, water, jacket) It rode great. I took it up and down some small and long climbs (for around here)..... and it was not a problem. It rode much better than i expected.

I think i am going to want to go with wider tires and i have to imagine with some weight on the front it will handle even better.

So far so good. I am liking this build.
