It is after midnight on a Friday. Why am I up? Why am I writing this? …Because I just finised rebuilding my ’07 Rock Shox SID Race.

A couple days ago the SID went from an 80 mm fork to somewhere around 35-40mm. Having previously killed a SID, I thought this one may be dead. Luckily, this relatively new fork is still under warranty. I called Karl and gave him the bad news, but decided to do a rebuild to see if things would improve.

I stopped by REI to get some shock oil. Apparently REI doesn’t carry shock oil. However, the friendly guys in the repair shop gave me some 15W SRAM Redrum shock oil for $2 (nice deal).

The rebuilt went well, and the Rock Shox rebuild procedures are pretty good (SRAM Technical Manuals). The fork seems to have 80 mm of travel now, or at least it has significantly more than it did before I started. I’ll take it out soon and see how it does. I don’t think the M2 is quite ready for fork number five yet…
