I don't think there's any universal agreement. In the absence of significant hills I tend to just stay in the large chain ring.

Nothing wrong with using a Cannondale touring bike as a commuter. My primary bike for the last 16 years and 150,000 miles has been a 1990 Cannondale and I much prefer it to steel road bikes I've...

Sorry to hear of this fatal crash. I've crossed quite a few cattle guards and they do vary considerably in how harsh they feel. Hate when they suddenly appear when rounding a curve on a fast...

I've always gone through Sunol to Niles Canyon and Mission. Or you could use BART from Pleasanton to Warm Springs.

I find mountain bike shorts to be convenient for utility bike rides. They have some of the usual padding but also have pockets and look more like regular shorts.
