Weather on Skyline

Current weather on Skyline Blvd in Palo Alto. This will come in handy.

Two more nice recumbents

Both the Kouign Amann LD and John Morciglio’s M1 are pretty cool looking.

Roadracer fenders

These fenders are my next set. Super-slim and clean, they also stabilize themselves using felt pads which clean your rims as you ride.

Low-riders

Some very cool recumbents from RaptoBike. Low Racer is really low; Mid racer takes up to 2 700c wheels. Might have to give one a shot.

Spring-loaded hub smoothes out your pedal stroke

This looks really interesting, and jives with my own experience surging on climbs with each stroke.

The folks at [RoadBikeReview are skeptical](http://forums.roadbikereview.com/showthread.php?t=155208), as are [the commenters at Bicycle Design](http://bicycledesign.blogspot.com/2009/10/e-hub.html), but while I admit any energy storage system will lose some amount of power, the benefit of reducing acceleration and deceleration on climbs may be worth it.

Insane bike tricks

This just gets crazier and crazier…

Hemingway on cycling

“It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” – Ernest Hemingway

Cycling cadence to match heart rate?

Crazy cycling thought of the day:

There’s been a lot of research on how your cadence affects your heart rate–for a given power output, there is usually a cadence that creates the lowest heart rate for an individual.

But could there be a correlation the other way? What if your blood flow worked best when pumping at a similar frequency to your pedaling? It seems to make sense that oxygen would best be replenished at the same frequency it was depleted.

Given a bicycle with [infinitely-variable transmission](http://www.fallbrooktech.com/02_Demo.asp), might you find good results by matching your cadence to something like 1/2 your heart rate, e.g. 90 rpm for a heart rate of 180?
