re:Shaft drive bicycles?

Can anyone comment on this link:

Seems like it might actually work, but I wouldn't take their word for it.
Would be much more interested if they offered the shaft separately, with hardware for crank and hub.

re:Gain ratio and other methods of gear comparison
In category Tech issues
Written by roland_bloodthunder

I recently read Sheldon Brown's intriguing proposal for a universal system of gear comparison which he calls "gain ratio" (name attributed to someone else. see http://www.sheldonbrown.com/gain.html). What do others think of it and why hasn't the system gained more "traction" in the cycling world. Or has it?

As an engineer, I am attracted to the unit-less-ness of it, though I haven't yet figured o

I recently realized that I have quite a bit invested in 7- and 8-speed drivetrains on 7 of my 12 bikes. I have a need for a gearing range that is not provided by the latest standard crank offerings, so converting to newer cranks is not a viable option. What I need, and what most everybody needs

Surly CrossCheck frame, but since I'm a MTB guy, I have a few roadie-related questions:

1 - Shifters...I know not all Campy stuff works with Shimano, and vice versa. I prefer Campy levers (feel and name) but can get Shimano a bit cheaper, and am

re:adding chainring to Trek 400
In category Tech issues
Written by OgieOgilthorpe

On an old Trek 400 series sport-tour bicycle, I want to install an additional chainring (somewhere in the low 30t range) so the bicycle can be used for moderate touring. Is installing only one chainring to the existing rings possible or will installing a whole arrangement be necessary? If possible, what type of technical issues do I need to be cognizant of? For instance, will the front derail
