I'm not quite in the 50+ bracket yet (I'm 39),and am more mtn bike than roadie (though I get manymore road miles in,but I digress...); I sold my Vassago Jaberwocky earlier this year (April or May) to help fund an Xtracycle build,making this the first time in a decade I haven't owned a dedicated (and very muc so used) SS......I'm currently sceming how to build another budget SS to play on. I used my old Monocog (sold last year when I built the Jabber,I'd had that black bike for 9 years) for commuting back in my working days,though it was considerably shorter a commute than yours. I just love both the simplicity and the challenge
