Kaito: Well done! You'll need an 11T cassette, I think.
Thanks!

I think you're right about the 11t..! I can't pedal the bike more than 40-42kms/hr, and with the MuP8, I was closer to 50..
Once it arrives, I'm hoping the bigger 55t in the front will give me my speed back. What do you think? If not, will I be able to add just a 11t cog onto my current cassette? If I have to, I will. I'm really set on getting the bike set up like I prefer! It has a TON of potential, & I feel like I'm really tapping into it!
Where did you get hold of the Airnimal stem riser? Do you know what its mass is?
I got the stem with the bike, from the good folks over at Calhoun Cycles.
With a shim, sorry - but don't know how thick, the Airnimal stem just barely fit snug enough. The mech. at the LBS had to apply some kinda liquid that he said had some particles/bead, to get it to clamp down and stay snug. The stem/bar doesn't detach since it lost the quick release in the process, but I rarely take off or fold a bar, so no issue for me.
I didn't get a weight on the Airnimal stem riser, but I would dare say that its prob half the weight of the steel Xootr one. Sorry, since its fairly permanent, I can't unbolt & weigh it right now..
Set up the wireless Cateye today, and fit a water bottle clamp/cage onto the seat post. : )
I'll update another pic once the FSA crankset's installed.
