Well, I finally got around to getting the Vesta converted from SS to Alfine 8.
I had built the wheel a few weeks ago, but I had to order a new chainring cog (50T instead of 55T) because I could not get the sliding dropouts quite far enough forward (like 1/4" away) to properly install the rear wheel. After doing a number of iterations on the Gates Belt Drive drivetrain calculator, the best option was the new chainring instead of a longer belt.
I also ordered a 113mm BB to achieve a proper chain line (er, belt line?).
So, it is all done.
I took the bike out for a "dial in" ride, and it performed flawlessly. The rear wheel was great (nice to know I can still build a good wheel), and the Alfine was silent and quick.
The J-Tek shifter was a joy to use. I know it sounds wierd, but it was. The bar-end is extremely solid - very well made. The shifting action is delightful, with a buttery smooth feel and a rich "click" that reminded me of the sound of a high quality camera shutter (remember those?). I am very impressed with the whole system.
The Alfine is a significant improvement in quality and in operation from the very good "non red band" Nexus on my Milano.
I love the belt drive combined with the IGH - it is a match made in heaven.
What's next? Front wheel dynamo build with a Mavic 719 to match the rear and dynamo lighting front and rear. I'll probably focus on my Marinoni project for a while now and enjoy riding the Vesta
