Last weekend I got me a Birdy.
It came with the wrong stem so I couldn't ride it for a week.

The dealer assured me all models had the sport stem as standard, but no, it came with the backwards comfort stem.

But I got the right one this Friday and quickly installed it along with the mudguards. But wet weather meant I stayed indoors, didn't want the new bike all dirty...
So yesterday at noon when the roads dried up I took it for its maiden ride to the local peak ride (on which I also live), and today on a gentle pootle on some newly-discovered singletrack.
What a pleasure to ride!

I got the tyres at 90psi but it still feels like I'm riding soft Big Apples. Steering is not twitchy *at all*. It surprised me.
Entry-level 8sp gearing but that's good - means I paid less ($1,530) and I will upgrade some parts if necessary. But it's working perfectly well. The first thing to go will be the Alivio derailer, that will get Ultegra, to improve ground clearance. I am thinking of keeping it 8sp, chains are cheap as chips so I can get a new one each few months, and have a bunch in stock for the price of a single 9sp chain.
I already replaced all the contact points, raiding some of my other rides (pedals from R20, saddle from Mini). It has Maxxis Birdy tyres.
The color is nice - a metallic off-white, like a pearl. I didn't like the idea at first but I must say its sensational in the flesh.
For now I have settled with the idea this will be an all-round bike so no weight weenie-isms, and the gearing is OK for now. I have the rack for the back (to be installed once I get the right one for this frame, got the older one) and lowrider front pannier racks.
Review after a week of commuting.
