I'm 72 and been riding a Trek 7000 with modified riser bars for several years now. Previously I had a soft foam Avenir seat, and I could count on having really severe leg cramps from riding, always occurring at night, in bed! These cramps were vicious, and I came to consider them the price I had to pay for loving to ride bikes! :
But about a month ago I got a Brooks B68 saddle on the advice of what I read in these forums... There's no doubt the thing is firm (hard, actually!), and I really haven't ridden with it far enough or long enough yet to '"break it in", as they say. -But surprisingly enough the hardness of this seat causes me no pain at all while riding, nor after it either! And after using this saddle daily for a month now, the leg cramps have not occurred once!!
I have no idea why this should be, and y'know, I don't really care 'why' either! (I suspect it may be my brain telling my ass "Hey, we paid $123 (incl shipping) for this thing, so you'd damn well better not nurt!!!
But whatever the reason, I'm just happy to have such a comfortable improvement...! (I know the Brooks saddle thing does not work for everyone, so I'm just glad to be within the majority for which it does! )
Having said that tho, I should mention that because of occasional back problems I'm the type who sleeps on an extra-extra firm mattress, and when entering a room if I can't find a firm seat I'll either stand or ask the host if they have any wooden kitchen chairs around! I even prefer those hard fold-up metal chairs to any kind of cushy sofa or chair! So bear this all in mind before you take into consideration my appreciation of the Brooks line and run out and buy one of these saddles for yourself...
