Did you build the wheel yourself or buy the complete wheel from from bmsbattery.com? -Cliff

I agree with ratz. The backwash blinds when the lamp is back and can shine on my legs and feet. I use flashing LEDs that wrap around my legs just under my knees. I think the flashing and moving LEDs do a pretty good job letting drivers know they are looking at a bike.

Anyone know where I can get black anodized bar clamps? The shiny silver would look much better black. -Cliff

I replaced the straight slider with the curved slider, and replaced the stock S30 bars with Zipp Service Course 80 bars (42 mm). I've also added little barlets by cutting off the ends of TT aero bars and attaching them next to the bars as close to the slider as possible. Here's how it looks from...

Slim, I don't see how the chainstay extension will move my feet forward. When the pedal is farthest away my heel just touches it with a straight knee. The position of the bottom bracket is constrained by the length of my leg. Since the bottom bracket is a couple inches above the seat, it seems...

Yes, and in hindsight the Frogs might have been a better way to go given the not-so-walkable nature of the walkable cleats. But the ULAs work really well and my white Lakes with double-boas look and fit great.

Finally got the hands-free working today going up some slight uphill streets. Was able to go hands-free for about 100m, then take a left turn still hands-free, then go another 100m before the grade became too steep. Slight uphill is WAY easier than level ground or downhill. Why is that? -Cliff

I've been trying to ride my S30 hands-free lately with limited success. Best case so far is 4 pedal rotations. I can coast for a a while by hugging the frame with my legs. Any tips on how to ride the S30 hands-free? Lifting my legs seems to help a little. -Cliff

I started with SPDs, then switched to Speedplay ULAs for knee reasons. ULAs are super easy to get in and out of. Getting out easy is important for my city commutes. I've tried to pull out of them, but have never been able to do so. Maybe sprinters with tree-trunk legs can. The free float is nice...

What size hose clamp?

Either 49.2 mph or 47.0 mph depending on which Strava statistic you believe. Did it on my S30 on Bear Creek Road westbound descending past the pump house during the GPC (metric) Century. Caught up to a slug of bikes riding in the lane in pairs. Didn't want to pass by crossing the yellow line...

Slim, I'm concerned that a chain stay extension will reduce traction on the steep hills I frequently encounter in Northern California. Hoyden, the bars are Sunlite Pro Cruz: https://www.amazon.com/Sunlite-Oversize-Cruiser-Handlebars-31-8/dp/B016QRNQW4 I also have SRAM double-tap brifters. And...

Ratz, can you point me to a picture of Hardy's bars? I can't find them on the forum. How would you recommend cutting the fork stem down? There are a couple spacers below the pivot clamp. Should I move them to the top of the pivot clamp? I agree that the curved slider would help. Need to get...

The stock bars on my Silvio need to go. They are too high, and are cueing me to pull/hang on them, which is causing soreness that will likely turn into serious tendonitis if not corrected. I've attached a side view of how they look. I've read the forum posts on this topic, but I don't like the...

I will be there for Friday. Driving up and bringing my Silvio. Looking forward to it. -Cliff

I only see sliding friction coefficient for rubber on road in the article. The static friction coefficient will dictate the steepest hill that can be climbed. I put the spreadsheet on Google Drive. Here is a link: https://drive.google.com/file/d/0B6iQH3osKDkeSzRtV2JhZXU4eFU/view?usp=sharing...

We have a Thule T2. It works fine for carrying a Silvio S30 and Sofrider at the same time.

At Ratz' request, here is the math. I've attached two files. One is a diagram showing the forces acting on the center of gravity and the two contact points with the road. The other is the math. I also have a spreadsheet that contains the math for the three cases (no rolling or aero drag, no aero...

I worked out the math for how the geometry and mechanics of the bike affects its ability to climb, hoping that it might reveal something about how I could easily prevent wheel slip on the steep hills in Northern California. The math shows what others have pointed out in this thread, that if you...
