Another driving force for Another driving force for upshifts is a crossed chain. If you are in the small chainring and smallest (or small) cog then your chain could be crossed to the point that it almost rubs the large chainring. Maybe hitting a bump or something caused the chain to grab the...

A small part of me dies every A small part of me dies every time I see a nice bike relegated to the sidelines only to be used for entertainment/weekend rides! Reduced to a mere toy! And a Silvio is among the nicest bikes. Use the crap out of it. Treat it well, but use the crap out of it.

I'd like to see how Silvio 2.0 owners have dealt with carrying capacity. I am interested in the 2.0 and I would use it as my everything vehicle. It needs to be able to carry a load. Please post pictures if you can. Seeing different setups helps my imagination :)

+1 to Jeremy's post. In a +1 to Jeremy's post. In a perfect world I would be able to get a disc brake front wheel and a rim brake rear wheel. This puts braking performance where it's needed and saves a bit of weight and cost in the back.

those pipes are used during those pipes are used during production to keep the frame held stable. They are removed later.

pretty cool story about pretty cool story about recumbents and pedal fairings. read the following forum thread: http://recumbents.com/forums/topic.asp?TOPIC_ID=4512&whichpage=4

your feet do move quite your feet do move quite fast. Every time you pedal forward that foot is going even faster than the rest of the bike (excluding the tops of the tires) and your leading foot is the first thing that meets the oncoming air. I'm curious how he made a shoe/pedal fairing, though.

wow, you have been enduring wow, you have been enduring some serious crashes. I hope it gets better.

Well placing your water Well, placing your water directly behind your head like that does provide you with a good aerodynamic drag reduction. And wow, we either ride in different climates or you carry a lot of water. I carry two 21 oz water bottles and a 40 oz Nalgene and I still need to...

WOW that's FAST!!  Well done, WOW that's FAST!! Well done, both on the athletic performance and sweet aero outfitting!

I love the seatcushions on my I love the seatcushions on my Quest 1.0. They are easy to clean and show no signs of wear after 10,000 miles (and lots and lots of sweating). However, something about the bottom pan design isn't quite perfect for my body. After more than about 3 hours in the...

Wow.  Just wow.  She should Wow. Just wow. She should be severely punished. They should take away her license, take her car, sell it and give you all the money. Wow.

Thanks for the info, Ivan.  Thanks for the info, Ivan. The SRAM series with a WiFli rear derailleur is very alluring.

beautiful.  how does it ride? beautiful. how does it ride?

Most research like that is Most research like that is either numerical or empirical. Neither of those approaches result in a formula for optimum stability, performance, etc. There are analytical models of motorcycle dynamics. Motorcycles benefit from the fact that the human rider is...

yes, more drivetrain yes, more drivetrain specifics please.

Two things of note: 1) I Two things of note: 1) I wouldn't recommend water on the boom. This not only adds more weight to the steering body but it is loose, fluid weight. When your quickly changing the wheel direction during tricky maneuvers the dynamics of the water in the water bottle...

It is hopeful to think that It is hopeful to think that there exists an accurate dynamic model of the biker-rider system. However, it doesn't exist. The system is simply too complicated. There are decent models of two-wheeled inline vehicles alone without a rider. Adding suspension gets...

wow, I really thought your wow, I really thought your chainrings were elliptical based on that first picture. For those in the process of learning: It takes time but before long you will be confident and capable. Ride your Cruzbike everyday for every errand. I have been riding for 3...

Before going to clipless I Before going to clipless I recommend setting up an obstacle course in a parking lot or find narrow windy paths to practice your slow speed maneuvering. Do these maneuvers without taking your sneakers off the pedals. If you can handle yourself at very low speeds...
