Gents, I put a 14T sprocket on the front last night (650L). Didn't have a metric socket/wrench big enough for the right rear nut. Anybody know the size of that? Also, the adjusters are at 27, out of the green range and actually a bit past the red-not sure if that is acceptable or not. Only 90 miles on the bike, I wouldn't think the chain is even done stretching yet.
