Don't get a 9 speed nickel plated wipperman connex if you have a road triple at the front.
Running 30-42-52 Ultegra front and 11-32 Deore at the back, the chain rubs on the "bridges" of the 42 ring that help with shifting when you downshift to granny ring, and then jams and comes off when up-shifting.
E-mailing Connex about this, who are helpful but until it's sorted get a shimano 9 speed if you have road front
