    Assploded Ultegra rear derailer today.

    Went to the regular Monday club ride from my local Bike Shop. Lots of people showed, at least 20-25 people. Good weather and looked to be a great day. Got the new Garmin 200 all synched up. The "B" group headed out. I started across the main street and BLAMMO. The rear derailer shuttle wheel hanger exploded. Don't think it broke any spokes. But it did snap the rear hanger.

    Now I gotta track down a hanger for a 2005 Fuji Professional. Gonna call a local Fuji dealer in a coupla minuits. See if I can locate one. I hope I can find one. Gonna be a bummer if I can't. I'll replace the Ultegra with a 105 unit. I can't see the added expense.

    I'll report back. If anyone knows the part number I'd love to have it.

    Bummer.

    I've got much to learn about cycling and BF. I thought only carbon parts could assplode?

    I aslpoded nearly my entire RD on my LHT. Bent the hanger slightly one winter and procrastinated on the repair until I forgot all about it. Took the bike out in the spring to train for a tour. Thought I would see how the lowest gear was on a steep hill. Shifted the cage into the spokes. Kaboom! Hanger twisted like a pretzel and the cage flew into a bunch of pieces. Had to skateboard home. Fortunately, the hanger could still be bent back. Otherwise, it would have mean a trip to Bilenky.

    The trunnion is twisted to hell and back. The pantagraph is also tweaked. The rear derailer is toast.

    The derailer was on a carbon frame, thus the assplosion.

    The local bike shop has the hanger and a new 105 medium cage rear. The medium would be better because I'm running a triple in the front. The tripple didn't help the Ultegra derailer. I was pushing the chain wrap spec on the Ultegra. The new 105 should handle the current setup just fine. Should be done by Friday. Just in time for Saturday's ride.

    I had another Fuji dealer order me a hanger as well. After Saturday's ride I'll run the 30 miles and pick it up at the Fuji shop. A handy excuse to check out an newshop.

    I'll report back how things go. Looks like the rear wheel was untouched. I'll give youse a report later this week.
