Personally I run Jpegs on my street bike, they're cheap, they hold up. Bada bing. 3 anti-roll holes, quality straight guage chromoly, not superlight but who cares? Leave pointless gram-grubbing up to roadies and people who can throw money away. My street bike weighs 31lbs. I'm stoked, don't care if it's lighter. It's strong and reliable without being overkill. Mission accomplished. Now, my road bike tips the scale at 19.1lbs and she's a pig, needs to go on a ******** diet. Different priorities and expectations for each of them.
One of these days I NEED to get around to upgrading the ghetto-ass steel noname flatland pegs on my Quamen to Sirencers, though. Those are teh_sex.
