Couple of updates I have made:

* Chaintug. Keeps the tension just so.
* Replaced the front wheel after tacoing it in a fence.

Couple of changes I'd like to make:

* Upgrade fork to carbon w/disc mounts
* Upgrade front hub to take a disc brake
* Upgrade brake
* Fit short mudguards
* Replace Armadillos with something a bit more grippy

Other than that, I highly recommend fixed/SS for commuting. It's very reliable.
