The B73 has a decent size for most riders and has 3 springs, all vertical. Very very springy, I've ridden a chinese copy, and it can absorb a lot. The B190 is larger, and has an ungodly number of springs. At one point I rode a B135 which has the same saddle shape and size as the B73, but the same spring configuration as the B190. Rode it on some seriously bumpy roads on a rigid frame. Hardly felt a thing. I warn you, they are pricey.
Use the B190 if you're (ahem) ample. Another option to consider is the B33; also a large "heavy duty" springy saddle.
These springy saddles are comfortable more or less out of the box. My B135 was like gliding!
For the most part, a B66 (or its modern 2-rail cousin the B67) will suit you fine, it's more modest in price and has a pair of springs in the rear, and is large enough for most folks.
Brook's website has very detailed stats and good reviews and pics of all their saddles. Make a choice there, and then buy local. Some shops are generous and let you return them after a few weeks and give you store credit to buy another brooks, if you want another style.
If you are trying to imitate an early 20th century American motorbike, go with a B135 or B190. They look the part. They have that certain excess that screams AMURIKUH!1!
I wanted to know, Which is the B73 or B190 that gives plushy or comforts when hit bumpy on bad roads and What's difference between this 2 items? I am using the Yuba Mundo cargo bike.
here the 2 links: B73
