I've been using a backpack for most of my commuting duty, but frankly thinking about getting everything but my macbook off my back and using a seat post mounted rack from topeak or ibera or etc.

typical packing each day would include work clothes (pants/shirt/socks), some food, maybe some odds and ends like my lock, keys, etc. I only have enough $$ for one bike, so I don't want to get a specific duty commuter and will be using it on my road bike (i've been commuting on it for some time now) and it doesn't have mounts for a full rack setup.

thoughts??

If you get that beam rack with side supports
there are rack top bags with opening side pouches for overflow that will hang down like Spaniel's ears
so then the side loops keep things out of the spinning rear wheel ..

no carbon fiber seatposts .. only mount the rack to a solid metal one ..

I had a seat post mounted rack when I first started commuting and really, really hated it. I found that no matter how carefully and tightly I installed it, it would move from side to side as I rode. It also bounced terribly if I had to go over even a small crack in the pavement, and forget about it on railroad tracks. Once it bounced so hard that it messed up my fender.

I ended up getting a regular rack and mounted it using p-clamps. I did have an eyelet on the dropout, but if your bike doesn't have one, I believe that you can share the same hole the axle goes through.

i'm planning an upgrade to my road bike this year, but I'm not getting a carbon post, I simply can't afford a bike that comes with one LOL

I do want to be able to strip it off quickly for weekend rides, which is part of the attraction of the seat post mount for me.

I use one: Amazon.com: Mountain Bike/Bicycle Black Rear Carrier Rack Seat Post: Automotive

It works well enough, though it sometimes does get off centre - typically because I'm carrying a load that is.

I combine it with a trunk bag: Robot Check

They don't play well together, however, as the bag likes to slouch much more than it does on a regularly mounted rack.

Had one, hated it, got rid of it in a month or so. It really messed with handling, especially when out of the saddle, and it always felt weird. I like Ibera though and kept the bag to put on an Ibera standard rack.

As other people have said, the problem with most seatpost racks is that they don't stay terrible secure. It's far, far better to put a regular rack on a bike.

Yes - even for bikes without rack mounts, it's possible.

They all attach at the bottom at the wheel skewer, and at the top at the brake bridge. You can also get a seatpost collar that has rack attachments -

I know that's not exactly what you're looking for, but I've looked, and what you're looking for doesn't exist - at least in a version where the rack doesn't sometimes swing around in a way you don't like. With a seatpost collar the rack will look sillier when on the bike, but be quicker to put on and off if you want to put a few minutes into doing that each weekend. With the brake bridge mount the rack doesn't look out of place, but does require messing around with the brake bolt if you want to put it on and off.

You can add me to the list of those who tried a post mount rack and hated it. I still have mine. C'mon over and I'll give it to you, free.

I tried one on my first commuter, I tightened the sob down good mine never moved but it didn't carry much more than a pair of jeans, shirt, tools, mini pump and spare tube.

My buddy uses the ibera bag with the post mount and he likes it. I use the ibera with a standard rack.

I wonder where y'all are that you don't mind backpacks or messenger bags. I didn't mind them in winter(much). But now that spring and 85+ is starting? Ugh, no. I can't imagine. Especially in 95+ degree heat with very high humidity(which is pretty much 1/4-1/3 of the year).

I've been using mine and find it works well. I've used with both a single and double panniers

Mine worked OK until a weld broke and it dropped on my rear wheel. Not so great to happen while riding along. Never really liked the weight up so high. Then I switched to a Topeak rack and bag system, and have been totally satisfied.

Seat post racks often don't drop down far enough to put a decent sized bag on them. I rigged up a whole separate seat, post and rack for use on my road bikes. The first rack I bought was a Blackburn from a C-List ad. It had hardly any drop and ended up being useless.

I bought a Schwinn model available at Walmart and it works great. Comments on the item on Amazon have complaints about it not staying put but I found the threads to be "coarse" and needed grease to tighten up.

I paid $17 for it, then a week later the both Amazon & Walmart are listing it for $9.80. Can't beat that!
