also found along the way.... read up. your noise is probably not the BB actually failing... unless the bike was ridden to death, or neglected and left out in the weather for years... PS.. i've had luck adding a bit of extra oil to the SID forks to help end the bottoming out problem...

★★★★★ Strength:Very light and responsive. Easy to manuever through technical singletrack. Hayes discs work great.

Weakness:Icon stem, bars, and seatpost. Bike creaks a lot, but I was able to fix it. Not very impressed with the sid so far after coming off of a 100mm manitou x-vert. I guess the shock is lighter, but it doesn't perform like a manitou. I'll give it a few more months and see.

So far I like this bike. It handles the singletrack nice. The sid is a little unforgiving, but it's very light. The only thing I didn't like about this bike so far is the awful creaking coming from the frame. I was able to fix all the noise pretty easily. If you have the same problem listen up. The seat tube has a shim in it that comes loose over time. You need to get green loctite [bearing and bushing] retaining compound to fix the problem. I think the number is like 640 or 680. Makes sure it's not threadlock or it might not work. It specifically has to be retaining compound. It gets into any gaps between the shim and fills them. First take the seat post out. Dribble plenty of loctite compound down the seat tube. Let it get past the shim(about 3-4 inches). After it passes the shim, turn the bike upside down to let it work into the gaps. Let it sit this way for a day or two. Turn the bike over and put the seat post back in. The noise should be gone. I also noticed the cranks and BB creaking. The cranks just need to be tightened and the BB was loose too. So far the bike has been beaten up pretty good on rocky singletrack and it's still quiet. I've only had the bike used for a couple of weeks and I've had to do these few things to it. It just needed some tweeking to get it set for my riding style. The times I had it out I loved it and the hayes brakes are awesome...

[NOTE: Remove the Bottom Bracket BEFORE adding any Locktite to the Seat shim... Clean any Green Locktite that dripped down to the BB area and threads BEFORE re-installing the BB. Also clean it from any inner surface of the Seat post shim...Green Locktite is a PERMANENT Glue, intended for retaining bearings and bushings in Engine and Transmission cases, Under Extreme Load situations.. and it works for that wonderfully....until rebuild time.. then you begin to hate green locktite.]
