Polygon Bikes Releases New Siskiu T Series
I'm just pleased to see the maker of a "Faux Bar" (linkage activated single pivot) actually call it a Faux Bar, rather than spewing a whole bunch of marketing speak about axle paths, and parallelograms. There is nothing wrong with a Faux Bar, but they make it seem like there is with the obfuscation.

Deviate Cycles - Press Release
Belts have more friction than a chain, at least under good conditions. This bike is already at a frictional disadvantage due to the gearbox and idler, so I suspect you'd want every advantage you could get in minimizing the rest of the drivetrain friction.

Deviate Cycles - Press Release
@ismasan: Yeah, the low COG on this bike, and low unsprung mass, will make a huge difference in the handling of this bike every instance other than a fire road climb. For straight up XC climbs the extra weight is a detriment, but for quick L/R handling and supple suspension, this bike has some theoretical advantages over a lighter overall bike with less optimal weight distribution.

Deviate Cycles - Press Release
@Racer951: Although you have to keep in mind that the idler is on the top run of chain, so it is running under high tension. That tension on the sprocket will add more friction to the mix and the lower tensioner, for instance, or the 2 pulley wheels on a conventional derailleur. I don't know what the figures are for the gearbox cogs in constant mesh but with no load on them, but it would be interesting to see a comparison. At least with a chain drive, tension on the chain makes a huge difference in friction.

Ridden and Rated: Six Flat Pedals
@TucsonDon: So your saying that Palmer, while a major figure in the history of flat pedals, primarily influenced popularity of the flat pedal style during the Baroque period, whereas Sam Hill's influence began during the Abstract Expressionism era and continues on to the contemporary Post Modernist era of flat pedal riding in which we live today? That makes complete sense.

Ridden and Rated: Six Flat Pedals
And Rob Warner, someone who is still very much in the MTB public eye. I would say it's classic millennial historical revisionism...except AJ is 37.

Look's New X-Track Pedals
@deeeight, your VRC knowledge is pretty much unrivalled, but it looks like you might be forgetting the original single sided Look ATB pedals that still used their 3-bolt road cleat and had a flat textured underside for pedaling while unclipped. Scroll to the 2nd to last item on this page: https://blog.performancebike.com/2010/05/13/flashback-friday-1987-pedals-2-0/ Old Sidi dominators had a 3-bolt pattern overlaid on the 2-bolt SPD pattern so you could use a treaded shoe with road sized cleat...actually it would be a pretty sweet gravel setup even today: http://i0.wp.com/www.cronoramia.com/wp-content/uploads/2014/01/shoesmtbsidi2JPG.jpg?w=400 Or do you not count ATB as MTB?

Inside Ortema - The German Custom Brace Producer
Classic unsafe German working conditions. They've got poor Kevin the technician there, applying epoxy resin with no mask, grinding and sanding carbon fiber with no mask, probably earning those super low EU wages. But what choice does he have, living in Stuttgart, he has to find some way to feed his family. And that doesn't even take into account all the ocean fill generated, clogging up the Rhine, just to produce a single brace to help someone deal with their 1st world problem. Classic corporate corruption... There is just too much wrong with the picture to even begin to get into it...

ENVE's New Carbon Rim and Protective Insert - Crankworx Whistler 2017
Internal nips require longer spokes, not shorter, all else being equal. Glad you like your wheels though.

Whyte S-150 Carbon RS - Review
@shredteds: http://www.nature.com/news/the-bicycle-problem-that-nearly-broke-mathematics-1.20281 http://www.cbc.ca/news/technology/science-of-cycling-still-mysterious-1.3699012 No, engineers/mathematicians/scientists have definitely not figured out how all this works. A lot of it, yes, but all of it, no. The problem is that, as much as people have defined certain elements that contribute to the self righting system that is a bicycle, it is possible to build one that veers away from those elements (no pun intended), and still have it work. Elements that were thought to be critical, as it turns out, aren't.
