I just fitted a new three bike roof rack. It's the Thule Aeroblade. I have lock cores installed so it is locked to the roof.
My biggest concern was that it would be noisy, but it is almost silent. Fuel consumption with just the rack doesn't take much of a hit, but with bikes on the roof I'm getting about 4 mpg less that the specified combined, although I have a heavy right foot so I doubt I ever got close to spec before the rack.
The only consideration I have ever had is vehicle height. I have a baby SUV so this would less of an issue with the Honda Fit. 
I went for the roof rack a) because the bikes cannot bang together and b) I can access the trunk without issue


I echo Ian's comments about why roof over hitch. They don't bang together and I can access the rear door (wagon) without issue. I know Yacks has a wagon too, so that is a personal preference.
Definitely fork mounts if you go roof rack.
Loving this discussion.  Trunk mount has proven to be a PITA so was considering a hitch or roof rack.
I was partial to Yakima because my first car was a Beetle and the rain gutter moved in two axis and I had to go with Thule because it was an unbeatable price.  The rectangular bars and non-pivoting gutter feet were hard to work with; I would have been better off with Yakima.  With most cars these days, the roof and mounting points are pretty much parallel, so there's little worry of what I had to deal with.

I like the lower fuel consumption of trunk racks. It's also better for turning.  That written, the convenience of having the trunk/hatch free is unbeatable. and I feel the bikes are safer (not going to be rear-ended, aren't slamming together, no hot exhaust to heat the tires/rims, but possibly gunkier after a rain)

I strongly suggest fork mounts.  Lower, for better balance, and potentially more aero.  

Rocky Mounts used to be super-cheap and worked great.  Actually, I have three long fork-mount trays (red, yellow, green) of theirs and some Yakima rails I should probably get rid of.  

I had a fairing on mine, which I still have, and I hoped it minimized the increased fuel costs, particularly when the bikes weren't up there--actually, if a fairing does any good at all, it will eventually pay for itself and save you money in the long run.

Cool thanks guys. I'm going with fork mount for sure. 




My Thule setup; works well for three. The faring makes a huge difference for noise reduction
Warning No formatter is installed for the format not-found
@Gwynna Maybe check the fork mount itself is locked down tight on the rail. Ian's new rig loosened there after a bit of use.

Gwynna - if in doubt - put someone else's bike on the roof and drive around to try it out. 

It's what I did with John's rig :-)
One vote for roof racks.  I just think they look cooler.
its the pro look
Yeah, I was a bit puzzled when Ian's bike was in the trunk.
Good thing we didn't go through the drive-thru ATM.

Spamming here, this Sunday the 6th we'll have the BMC demo truck in action from 9-4 if you wanna ride something cool that isn't yours. Also, we'll be streaming Flanders. It'll be a party!

Another DEMO DAY alert in few weeks. Parlee demo on Sat, April 19, 2014 from 8:00 AM to 4:00 PM at Redbeard Bikes in DUMBO: https://www.eventbrite.com/e/parlee-demo-day-redbeard-bikes-tickets-9644082711 Them some nice bikes.

Hey Folks.

I picked up a set of the Ritchey WCS Zeta II road wheels. 

http://ritcheylogic.com/road/wheels/wcs-zeta-2-road-wheels.html

With our discount, they were very affordable, sub $500 

Took them out for the first time with new Conti 4000s in 25mm. The ride is amazing. Seriously, compared to my tubeless ultegras these feel really plush, absorb the rough road nicely, and spin really well. The braking surface "catches" the pads so well that I skidded to a stop unexpectedly twice on my first ride. 

Anyway, there is only so much you can tell from one day of riding to FBF, racing, and heading back but if these wheels hold up they're a ridiculous steal. 1444 grams and come with a nice set of skewers.

Could you put some calipers on them and measure the rim width from exterior wall to exterior wall?  Ritchey only lists the inside width?
Yup next time I'm at Eric's or the bike shop I will do that. I don't own calipers .
Now that the wheels I just built have been destroyed...I might be up for some Zetas
Brendan,
I doubt your wheels have been totally destroyed. Hub must still be ok. Some of the spokes still ok? Just buy a new rim and start again. Second build will be much easier and much better. Regard this episode as karmic forces pressing you to practice your new-found art form.
 
Brendan...get the Zetas...they are an incredible value with the discount.  

here is the correct answer:

Get the Zetas and rebuild your other wheels. 

Seat post question. I'm moving to a 0-setback post so I don't look so dorky. 

How does one choose a seatpost length? I only have 75mm exposed above the clamp. I ride a 56 cm frame. Can I get away with a 240mm seat post? It saves some weight over the 330mm post. 
Look at Konrad's. Measure how much is below the min insertion line. Then add that to how much you'll have exposed. Mark that length on the post.

Borrow my hacksaw.
btw, I once cut down a seatpost.  It was a fairly light one, American classic's old design.  I cut off the equivalent of the minimum insertion or thereabouts.  I think it saved me 10-15g.  Cutting down a 330 or 400 would have been different.
I cut one too. A Thompson. I never weighed the difference. I figured avoiding a muffin once in a while would be better weight savings.
Mike, I've read that you need to have 100mm as a minimum insertion length. Can't remember where I read that, but it's also stamped on most posts. I've cut a couple and opted to add a little extra to be safe, so I went with 120mm

My question wasn't about cutting. It was about how much post needs to be in the seat tube as a general rule of thumb.

The highest estimate I've found is 100mm, so the 240mm post should be plenty long unless I'm missing something.

just pointing out that posts are often long for people about my height and ride a Cannondale.

Nothing.  250 would be plenty long.  200 would work, too, if you could find one.  180 would probably be a bit too close for your comfort.

Then again, I haven't seen a 220 length available in a long time.
