ok here you go

handle bar $25 http://store.velo-orange.com/index.p...-22-2-dia.html

brake for new handle bar $12 http://store.velo-orange.com/index.p...es-levers.html

if that is not tall enough then higher stem taller, more verticle stem $60 http://www.rivbike.com/product-p/st4.htm or $50 http://store.velo-orange.com/index.p...uill-stem.html

or you can go stem first and keep handle bar, but that is not what I think you want

another brooks to look at is the flyer...essentially a b17 with springs

my version of higher seating position
