I just dug into my records. If you want to make your own Ti shock bolts for a Revved frame with alloy rear, you need to order some M8 x 1.25mm thread pitch parallel socket heads. You need 40mm unthreaded length (rear) and 25mm unthreaded length (front). Standard bolts of this type have a max of 25mm thread length, so I had to buy a 65mm for the rear and a 50mm for the front, and cut them down with a Dremel tool. It took like 15min per bolt, really slow going. I got the bolts from RaceTi.com, they were about $5/ea and $7 shipping.

There was another local guy who had a GG and he was complaining about the seat/seatpost creaking. He even shipped it back to them, they inspected it and said it was fine. I don't know if he ever got it fixed before he sold it. I do know that a lot of GG bikes come with BikeYoke droppers, who did a running change to the saddle clamp heads & bolts a few years back to address creaking. If you've got one of those droppers, you might want to look into that. When I had a 185 Revive, switching to the new head did fix creaking for me.
