More Aerodyamic Mounting for NR Lumina 650 Light Decided to change how I mounted my lights. I use the NR Lumina 650 in flasher mode -- front and rear. The new mounting technique is a little more aerodynamic now. Pictures below: FRONT: REAR

Seat Stay to Rear Triangle Assembly Counterpoint .... If you haven't already filed your rear triangle, you may try tapping on the offending side of the rear triangle while blocking that side of the seat stay. I had a similar experience while assembling my Silvio. The fit between...

Water Bottle Security on Silvio 2 Seat Back I have not had a problem with cargo falling out of water bottle mounts on the seat back of the Silvio 2. I say cargo because I have never carried water bottles back there. I have carried pickle ball cans filled with whatever. I just weighed the...

Other Uses for Water Bottle Holders I too have mounted two water bottle holders behind my Silvio 2 seat back. It just seems a natural place to store stuff. Although, most of the time I don't use them to hold water. I store other stuff back there. Without fenders the tires kick up a lot of...

External vs Internal Di2 Battery Mount In the context used by Planet Cyclery, "internal" or "external" refers to how you plan to rout the wires. Well..... sort of. It's a little confusing. The Planet Cyclery internal upgrade kit is the same as the external upgrade kit except that the...

Details on Di2 Groupset AggieRay74 ........ I bought an upgrade kit from Planet Cyclery. The cost was $1,148. It was their part number GSX1040-1-PMFRB (2013 Shimano Ultegra 6770 Di2 Upgrade Kit Internal). You can see what is included on their website at...

Night Rider Luminous 650 On Silvios 1.5 and 2.0 The photograph below shows one person's choice of lighting for Silvio 1.5 and 2.0. I chose the Night Rider Luminous 650 because it is bright, has a high endurance flasher mode, and has a self contained, rechargeable battery. It also has three...

Chain Stay Differences GT .... I did not have the 100mm chain stay extension on my Silvio 1.5. In my opinion elevating your feet and legs by adding the 100mm chain stay extension will tend to lower the drag. Since the time of posting I have played more with the data. My best fit (by...

Maybe a little grease will help Jeremy .... I use SPD pedals too. I have noticed that when new, they are a little stiff. I like them better when they have a little wear. As a matter of fact, if I sell a bike, I buy new pedals to sell and keep the old. My experience is that a little...

More Analysis Doug ..... Thanks for your help. I am using the SRAM Quark (Riken) power crank. Picture below. I chose it because it allows me to use wheels of my choice. On the Silvio 1.5, I mounted the magnet that came attached to a ring between the GXP bearing and the...

Drag Area pugwash .... Thank you for adding the drag area computations. The 100 KG assumption is accurate. I agree with your conclusion. Kavman suggests switching wheels, but because of the way data is collected here, I doubt we will be able to see the difference. This does not...

Just for giggles, I plotted some average power vs. average speed data for the Silvio 1.5 and the Silvio 2.0. I think you will find the data interesting. The vertical axis is average power in watts. The horizontal axis is average speed in miles per hour. All data points were...

Kline .... In answer to your Kline .... In answer to your question about my mirror, I purchased it from Calhoun Cycles. The web page is : ?http://www.calhouncycle.com/productcart/pc/Mirrors-c9.htm. I got the information on a post that Ken Hardwick made some time ago. If you search...

Jeremy and Elliot ……   My Jeremy and Elliot ...... My Silvio 2 build is pretty much "off-the-rack". It has similar lines to Ivan's build, as I am using the 100mm chain stay extension, and I am about the same size. My uninspired pictures are below. The build you see is how it was today...

I have recently completed the build of my Silvio 2.0, except for the dozens of tweaks that will occur during the first several hundred miles or so. I have not seen a lot of posts related to mounting Di2 shifters on a Silvio, so I decided to share my installation. This task was made easier...

Seat Security Eric ... Thank you for all your excellent posts on the new Vendetta. I presume you transported your Vendetta inside your car. In your opinion how would the seat pans (the fiberglass pieces) hold up if you transported your Vendetta outside of you car? Buddy

I have mounted a Brain-Box on my Silvio using several lengths of PVC tubing and elbows. The finished product is shown below. The installation uses two existing seat holes in Silvio 1.5. It has proven to be relatively stiff. I use the strap at the base of the Brain-Box to snug...

The bungies are strong enough The bungies are strong enough to securely support the 800 gram load. Add a lot of weight and it will begin to get wimpy. I have not tested the limits, but I would suspect 1200 grams would be close to the limit for the small bungies that I am using.
