First time poster, long time lurker here...
I want a new saddle. Mostly because I want my SS-beater-city commuter to look better. No real long rides and buns of steel means comfort is a minimal, yet not entirely moot point. More specifically, I want a cheap orange/white saddle (it will work, trust me). Here is a cheap BMX seat that I like:

1. Will it fit on my standard old road seatpost? (like, totally right?)
2. Will it be really really uncomfortable? (cmon, BMX dudes don't sit on their seats)
3. Does a BMX seat have really different look/proportion that will be patently absurd on a road frame?
4. Other suggestions for saddles? (if you post a link to the fizik hotness, I will explode with desire (again), collect myself (again), and come to the conclusion (again) that it makes no sense to put that on my cheap ass commuter bike.)
5. Why do BMXerz call em "seats" while road dudez call em "saddles?"
6. Why do I kinda want pegs? (you know, for taking chicks home from bars...)

BFSSFG fashionistas I await your judgment.

I don't know where else your going to find a $20 orange saddle, so it might be worth a try. It really depends on how far you ride. I would probably use just about anything for 5 miles, but that probably won't work on 20+ miles rides. If I were you, I'd probably head to a bike shop and ask them if they have any "new take off" saddles. They should have something in the $5 to $20 range that will work much better than that bmx "seat".

I have been thinking about the exact same thing recently. I have an orange seat and orange grips from a bmx bike that I have been considering throwing on my SS mountain bike when I get it next week. And have also been wondering if the sizing will be compatible - my impression is that seats are pretty standard in the way they attach. At least, i've replaced a couple seats before without any problems like that.
The grips, I dunno... but that is my problem, not yours eh.

BMX seats tend to have quite thick padding, as they are not really made for sitting on long term, and also function as pads to protect you when you take a slam. Too much padding means your butt muscles and genitals get compressed back against your sit bones, so you may experience discomfort, chafing and numbness if you actually have to ride your bike any distance.

They are also heavy.

But if you can live with the above, then I am sure you will have them lining up to ride on your pegs.

1) Probably not. If it fits it will be a VERY tight fit. The rails on road bike saddles are 7mm thick. The rails on BMX seats are 9mm thick. When I used to ride BMX, I'd run BMX seats on ultra light road seatposts (Thomson) and it was a B*tch to squeeze the rails into the clamp.

2) Probably.

3) That's up to you.

4) The saddle is the #1 upgrade for new bike owners at bike shops, so every bike shop has a box of stock saddles (road and MTB) that customers had replaced. You can get them for like $10.

5) ?

I've used the same exact seat and no issues with the rails fitting.

comfort however is another story. It was ok for riding around for errands, to the store, etc...but not too comfortable for long rides.

Also, the seat is smaller than most standard road saddles.

1. Maybe. Depends on your seatpost. If it's a two-bolt style, you might have trouble. Single bolt, less trouble. Ancient-style seat-guts on a post style, probably easy as hell.

2. It'll be super comfortable for the first 2 miles. Like riding a bike on the arm of your sofa. After a while it might cause trouble. Like riding a bike the arm of your sofa.

3. Some folks I know ride BMX race seats all the time.

4. I like the Selle Italia Turbo Matic.

5. Because they use them differently. A seat supports your weight entirely. When a BMX kid sits, that's what he's doing. A saddle only supports you somewhat; your arms and legs are still doing a lot of the work (like on a horse, also a saddle).

6. Pegs rule. I am fantasizing about an old track frame with a coaster brake, platform pedals, risers, and pegs.

do it!!!!!!

Agreed. I used a single bolt.

no it wont work it has 8mm rails if you want a bmx saddle go old school or just get a road saddle 7mm rails

Do it.
A seat by any other name would be a saddle.
Whatever turns your crank; it's your crank.
Post pics, too, please.

yeah until you break your seatpost
