I saw a single-speed on the DD, btw. Now that's studly. (And that's precisely what I said when he rode by. :D )

me in this thread:
on topic: 2 (maybe 1.5)
off topic: 4

Did the single speed guy have a very long thin braid down his back?? We rode for a bit with a fixed gear guy w/a long braid. He was hard to ride with because we could so drop him on the downhills/rollers. So we had to leave him. But it was impressive nonetheless.

The singlespeed guy I saw (as he whizzed by me :p ) was riding a Rivendell Quickbeam and he was wearing #22 - that's my 'lucky' number which is why it stuck with me.

Even though I suppose a single speed on the Davis Double is not all that astonishing, relatively speaking. Easy for me to say of course.

Has anyone done the Devil Mountain Double on a singlespeed ? That would be mind-boggling.

Wild. Well, my guy was fixed gear, non-Rivendell, so they were different crazy people.

yep. According to Ed, he towed their gang on a ride from Placerville to Pleasanton. No rotation in the paceline pretty much the entire way.

From my vantage point BEHIND jobob, there appeared to be some flirting going on with Mr. Singlespeed #22. I'd swear I heard a girlish giggle. And leebob only a few yards away! :p

#22 was Eric Norris who posts on the Rivendell Bike List.

Wow, connect the dots, Kim! This guy? Makes sense. He does live here.

Wow, now that it really crazy. Norris used the DC as a training ride for the Big Fix Ride.

Worthy cause, but fixed gear across the US? The SS idea is weird enough.

KelownaGirl,
lots of roadbikes have triples!! why would your husband say THAT??

So bottom line, all why would anyone want to get a compact double?
are they a lot cheaper? a lot lighter? what is the benefit??

Thanks

You asked why would anyone get a compact double? I am not putting down triples by any means, but I have compact doubles on both of my bikes. I switched from triples because they are mechanically simpler, which means they are easier to keep in tune. They are also lighter. In my case I had to switch because I needed a custom crank set to correct a 3 cm leg length discrepancy, and it was easier to build a double than triple to the specs I needed to correct my biomechanical problem. On my go fast bike I paired my 50/34 compact double with a 12/27 casette for a range of ~32-110, and on my touring bike I paired it with a 11/34 casette for a range of ~26-117, which both work well for me.

dumb question

OK, maybe not so dumb since I am a relative newbie, but can someone explain exactly how the whole number thing works? I think it has something to do with the number of cogs (is that the right word?) on the ring. Not sure how all the various numbers relate though. I have three rings on the front of my bike and 8 or 9 on the back. Do they have different names or are they both chain rings? What is a cassette? I want to go down and count all the thingies on my various rings and find out what I have but I don't know where to start. OK, that was more than one question... :) Thanks a bunch.

Oh, and I am now constantly spouting off the stuff I read here and can actually converse with dh about bikes and sound like I know something. He is also beginning to realize that lots of people have triples, thanks to you girls... TE is awesome...

Sheldon Brown's website ( www.sheldonbrown.com ) has a lot of really good articles and is a really great resource. Here's an article on gears and shifting that might help make some sense of it all. :)

My Kelly has a big gear of 48x11 which is bigger than the 50x13 on the Litespeed. It's the combo of chainrings and cassettes together (as in gear inches and ratios) you have to consider.

nice! thanks! Not sure I'm ready to switch to campy, but good to know!
