I'm new to this forum,and should probably stay quiet for a while,but....I have a gimpy neck(wrestling-football-54 yo),and had to quit biking years ago because of the seating position and pounding my neck and body were getting from the skinny tires no suspension bikes of the late 70's early 80's.I discovered suspension bikes in 2000,and that took care of the pounding,but not the bent over position.I can't be the only oldster that hates the bent over position??It absolutely kills my neck and does no favors for my back either.
With a road bike there are 3 modifications
1)Riser bars with plenty of pullback-4" or so
2)Biggest tires you can fit-35-38 mm will fit on most-so you can drop the pressure-soften bumps
3)Swan stem-adds 5 or so inches
4)If you start with a frame that is too big ,the seat will be relatively lower than the Handlebars.Of course-this has some downside-careful with the top tube.
MTB bike-same story
2)stack steering tube extenders and add 10" or so
3)Riser stem-45 degrees or so
Here is a picture of my NRS-yeah-it is the strangest looking bike you have ever seen-but it allows me to ride,so.
This is my old Mercian-sitting for 20 years(77 frame-components 78-79-some real period components-weight nut stuff-HI E hubs)-it has the riser bars-swan stem-yes it looks weird-I will be putting it back on the road(you folks have shamed me into it).I agree it is a shame to hybridize the Mercian,but...
Hope I can post these pictures.Thanks.Charlie
