Subject: Seat recommendations for leg numbness
My wife and I used to ride quite a bit (3 week loaded tour bicycling
vacations were our preferred vacation) but since having 2 total hip
replacements (both on the right) she hasn't been able to ride as much.
The problem isn't mobility in the hip joint, but progressive numbness in
the right (surgical) leg. She's now several years post surgery but the
problem persists. We've played around with seat adjustments and several
different seats (Avocet Women's Touring I and II, Brooks B66, and an
unspecificed wide, padded Bontrager seat I swiped off my daughter's
bike) with no real improvement. She's able to ride maybe 5 miles before
the leg becomes too numb to comfortably continue.

Anybody here had a similar problem, or better yet a solution? She has a
lovely custom-built TS Isaac touring bike that only gets used to go to the
local farmer's market. A shame...

Have you played around with the height of the bar? (Having it high
may not be the answer . . . )

Your problem may not have to do with the seat. Ever since I began
cycling over 15 years ago, I occassionally get numbness in my left leg
when going at a steady, moderate to hard pace. (Yes, I've been to
chiros, neurologists, had tests --- supposedy everythig is "normal!")
I've fooled around with my position more than you could imagine, with
little avail. I have noticed, though, that it seems to be worse when
I position myself in a stretched-out manner, keeping my back really
flat, with my hips pushed out & back. Its better when I keep the
reach fairly short, with a large 12cm bar drop, which gives me a bit
of a curve in my back. I also have the seat fairly far forward, which
keeps my hips more under my back, I guess. I have no idea what, if
anything would help in your case, but my point is to try the other
adjustments -- seat-to-bar and bar drop, and maybe seat fore-aft.
There may be no "cure," but you may be able to ease the numbness to
some extent.

We got some improvement by going to a flat bar:

But nothing else has done much. :-(

You could try some recumbents; with them, you can get a wider variation
in rider position than with upright bikes. Some are very upright/closed
while others are very reclined/open, and MOST people don't get nearly
the degrees of posterior/saddle problems on a recumbent seat.

Test ride first, as there are no guarantees with extreme injuries. Might
help, might not.
