Fingers: 10. Chainrings: 0.

Having just watched A Sunday In Hell at Morning Glory Coffeehouse, and being a little bored, I decided now was as good a time as any to start converting the Portland from a tripe to a compact double. I've been collecting parts since late last year, and at this point I have almost everything I need.

I decided to start with the biggest piece - the crankset. I was determined not to let any chainrings get the best of me this time out. I put the bike up on the stand and got started. Just like when I switched cranksets on the Bianchi (the stock FSA Gossamer from that bike would be replacing the 105 triple on the Portland), I had Crank Brothers Eggbeater SLs installed.

The one annoying thing about the SLs is that they don't have a wrench face on them, so you're forced to use an allen key to remove them, putting your hand on the inside of the pedal and in direct view of your carnivorous crankset. I wasn't about to rip up any of my fingers tonight, but I had already removed the chain from the bike and there still wasn't a really easy way to get decent leverage on the crankset.

Enter the rubber mallet. I set my Pedro's 8mm Allen Key Pedal Remover into the drive-side crank arm and gave it a decent whack with the mallet. One more time and the pedal loosened. No harm done to the bike, the pedal, or me. All I had to do was repeat the process for the other side and I was out of the woods. I was pretty happy. And relieved.

Now the Gossamer is installed on the Portland and the 105 triple is in a box in the garage. Next up: front and rear derailleurs (again, stock parts from the Bianchi that have since been replaced will allow for the conversion) and new cabling and housing. I've never messed with cabling at all, so that should be interesting. I hope this next phase isn't something that I start and have to let Pro Bikes finish.

Cabling shouldn't be too hard. Remember to file the cable cuts flat so they don't have too much give, then open up the hole with an awl.

I can help if you get stuck....
