    I have also done a little tuning work on my xtr mech. 960 longcage org 202.. now 161 with ti bolt for wire. I have order a dousin of al bolts, and a srp bolt to mount the mech to frame is coming.

    I've done custom pins (for the links) in the lathe with m4 screw threath in the end to make it possible to dismount. I have also made a pair of carbon plates in the miller with CC of 70mm (longcage is 87mm)

    otherwise I've change the end screws to plastic ones as the jockey screws.. the jockeys is homemade ones in carbon with smooth skf bearings.

    I wouldn't go AL for my RD pivot bolt. The first time you drop you bike on the drive side you lose your RD. This seems like a good example of foolish weight savings to me.

    I don't know. I just got my X.0 - the pivot bolt is drilled right through which is nice and it looks to be aluminum but I'm not 100% sure.

    Anyways, I think those aluminum bolts are pretty damn tough...

    5 years never broken one, they're tougher than you think

    I've broken 3 of them back when I had a SC Superlight (non-replaceable hanger). Each time it broke, it stripped the nub on the derailleur body rendering it useless and scatter the b-tension parts all over the trail. Not worth it. It's too bad SRP stopped making the Wreck-Defier which could be changed without removing the b-tension.

    in what ways was the Wreck Defier different than just the aluminum pivot bolt? Any pictures out there?

    Also, anyone have some tips on how to change out the pivot bolt fairly easily?

    thanks

    Getting it off is the easy part.

    Here`s what I do to get it back on. Put a 5mm allen tool snugly in a vise pointing upward, then insert the new pivot bolt into the deraileur body with all parts lined up ready for installation. Now put the pivot bolt (with all the parts lined up) onto the tool in the vise holding the parts together. Push down to compress the spring and twist at the same time to align the derailleur body to receive the retaining clip. Once the spring and derailleur body are in line and in their compressed state, you can install the retaining clip.

    Once you do it, you`ll realize how easy it is.
