Like the title says I guess. There seems to be quite a few suspension seatposts for MTB use but everything I have Googled or eBay'd seems to be way overbuilt for commuter use. Understandably so but...

Something relatively light and an inch of travel or less would be great.

Thanks

Fatter tires?

Brooks Flyer sprung saddle?

A Cane Creek Thudbuster ST, but only 27.2 or larger ..
Smaller ID seat tubes would get the USE, seatpost, a 25.0 telescopic type.
they machine shims to 27.2, then also offer a 27.2 version , as well,
and shims to fit larger seat tubes.

Both these can be refitted with different rate of suspension dependant on rider weight.

there are cheaper seat posts as well. they often have rotational play in the telescopic
mechanism, but are widely available .. if cheaper is priority..

I have an Airwings , a German made suspension seat post as part of an OEM,
My Koga, WTR Build,
but those may need be imported retail from EU.

Have a thudbuster LT on my Bike Friday, but it needs a long seat post extension
like sloping top tube frames may offer,
as the parallelogram linkage uses up 6 inches .
that too has multiple elastomers of various rates for the backside on the saddle.

+1 on the Thudbuster ST. We use it on our tandems stoker seatpost. Works great. Elastomer to use is based on riders weight range.

I put one of these on my wife's bike. I used to use it on one of my commuters (now a dedicated trainer). It works okay for the casual rider. The price is right. These days, I would rather have efficient power transfer than bouncing comfort in each pedal stroke.

Ding ding ding ding! We have a winner. A sprung Brooks will provide more than enough suspension for city streets. Posting over bumps is a better solution, even. Get yer butt out of the saddle!

Thanks for the suggestions. I looked at the Thubuster ST and Brooks options. Neither one is inexpensive. I'll probably go for the Thudbuster option after I get used to the price. I like Brooks saddles when fitted to a bike "work" on but one of the sprung versions wouldn't be right for my ride.

Thanks

Tamer offers three suspension seatposts from $40-$130. Plus you can buy direct from MRP if your shop doesn't have them.

One branded Poise XC came on my 2005 Bianchi Volpe. It is the telescoping type. It seemed to wear out faster than I wished it did (probably about 2,500 miles). It lost its spring tension after a while, such that it traveled more than I wanted it to no matter how much I cranked up the tension adjustment. I replaced it with a rigid alloy seat post and I've never missed it. Getting rid of it made a major improvement in pedaling efficiency, although if it wasn't worn out the difference might have been more subtle. I probably weighed around 185 lb when I was using it, so I probably wasn't loading it more than it was designed to take. After this experience I wouldn't recommend that anyone buy a cheap one, but maybe there are others that last better.

I have a Rockshox seatpost on one of my bikes. They don't make them anymore, but it is great for commuting on a harsh ride (Marin Mill Valley).

My vote is for this solution. My '07 Sirrus came with a suspension seatpost and the only thing consistent about it was it was inconsistent on returning to it's maximum height. Went to a rigid seatpost and a flyer and am much happier.

I have one that came stock on my Trek 7.2 - I am taking it off in place of another seatpost if you're interested. Its a 27.2
