Hi, I just noticed there was more info on the vendetta. I love the neck rest. Is that part of the bike or an add-on? On the silvio the position is upright enough there's no need for something like that, but I can imagine the vendetta being a different story. Is the riding position slightly...

I went on my first silvio ride of the season a couple days ago and was really impressed with how nice its ergonomics and drivetrain are. I posted a short writeup over on brol, but basically the bike's ergonomics are just great for generating power and the transmission is of course super...

I know I more-or-less disappeared after starting this thread, but I've read your progress with great interest. What you're trying to do looks great and I'm glad to hear the update even if it hasn't worked out as hoped yet. Best of luck with the project and keep us updated. Mark

I don't usually notice the new blog entries, so I only just now read the one titled "Starting at the back" about making a more reclined silvio with a lighter rear end. I love the idea, and was wondering if a tailbox would be a consideration on the new reworked rear. People always say a tailbox...

Good news: the threaded rod solution does work with the 1up trainer. I still don't know if the rounded skewer caps are technically required for stability, but I went with the solution in my last photo above and it feels quite stable. So here's a mini-review of it. The 1up trainer appears to...

Thanks for the fast response, I'm in the process of fiddling more but have stopped for the night because I doubt my neighbors would appreciate the noise my dremmel makes cutting through the threaded rod. First here's what my rod + washer + bolt looks like and a decent shot of the trainer's cup...

I just ordered the 1up trainer online: http://www.1upusa.com/bike_trainer.html and I'm thinking that may have been a mistake. [[ Update: I was able to make it fit, see later posts, and like the trainer very much now. ]] At its widest position it just barely has over 170mm between the cups...

Oh shoot, I meant to attach the photo with that post. Here it is. Mark

Okay, but it really is virtually identical to brewmaster's above. Mine is currently riding a tiny bit higher on the seat due to the tightness of that top loop of zip-ties, but I may loosen it and let it lower an inch. The only thing I think I did better is my water setup. It exits the bag at...

I just yesterday switched from my "old man mountain" rack+bag to the solo racer bag, following the same layout shown above. Now that I have the old rack off I have to admit it's not as heavy as it looks, but I'm sure the solo racer bags are lighter still. My setup isn't quite as slick as...

This topics reminds me, does anyone know the details of maria's bike setup? I remember john asking about interest in disc wheels recently and at least off-hand I didn't guess it would be that big of a win. But since maria seems to be the most serious racer we've got on the bike so far, I am...

I mostly doubt I'd buy a disk wheel for my silvio at this point, but I would like to see a rolldown test to get more data on how big a help they are. If you do such a test please consider equally weighting the two versions of the bike (probably just put an extra half bottle of watter on the...

Going back to john's response, I know it's possible for the wind to close back in, but I thought there were lots of bikes like the easyracers goldrush that put their fairing about arms distance from the rider's body and I've heard those bikes do very well with a fairing. They do better with a...

Man, I hate running performance tests and getting only semi-consistent results. I rode to a hill today that I thought would be a good place for some roll down tests. I tested it three ways: 1. fairing as shown in pics (relatively flat, just a little curve to it) 2. tightening that middle...

At first I was all proud of myself for making such a simple minimalist fairing, then I took it for its first ride tonight, and it was like dragging an anchor behind the bike. Below 18mph it was largely indistinguishable from before, but above 20 it was very noticably slower with the fairing...

I'm interested in your progress on the fairing. So what all did you end up having to buy to make it work, and how much skill was involved? Was it the hpvelotechnik streamer with what they're calling the standard mount? I'd love to try a fairing, but my mechanical abilities are pretty weak if...

Any updates? I'm looking forward hearing more about people's experiments with fairing options for the silvio. Around here the crosswinds usually aren't too bad so I think one might work out okay. - Mark

Are you sure angle #2 shouldn't say "desired angle between bottom dead center and the crank when the ellipse major axis is at the chain tangent point"? The way angle #2 is described above I think it is the 91.6 angle from your original diagram, where it sounded like you meant for 1)-2) to be...

Okay, I'm really surprised by that (defjack's q-ring position). It seems to me that where the chain begins making contact with the chainring at its largest diameter would put the cranks somewhere between horizontal and their current position in jack's picture. Compare that to mine where...
