he says it's a GT so long cage.
Super easy to take off the bottom pulley, especially easy to put back with the help of that nice exploded diagram^, the only trick is the nut for the jockey pulley: I've used needle-nose pliers but you might have to improvise something. Don't be tempted to remove the stop pin (22) cause you don't want to have to guess at the tension if the cage unwinds!
Good opportunity to clean everything up and don't forget a little lube in the sleeve bearings and under the dust caps.
Good luck!
