The '03 Riv was replaced by the 2020 Chauncey Matthews IGH frame. The proximate reason was to have a frame with new features: accommodation for 42s and fenders with an even fender line, internal dynamo wiring, cantilever bosses, special housing stops for a SA shifter/trigger mounted at the end of the right drop bar hook and obviating the need for a roller at the tt/st junction, 118 mm rear OL spacing to accommodate old 114 mm OL SA hubs as well as later 120 mm hubs, very long custom rear dropouts for maximum chain takeup, and a huge chain “hook” at the inside top of the right chainstay where I can hook the chain if I have to remove the rear wheel by the side of the road and keep it out of the sand (no pristine grassy verges here in high desert ABQ, NM).
But I also took the opportunity to specify modestly thinwall 531 tubing in normal gauge — I didn’t want the very thin .7.4 .7 because of reports of shimmy so I spec’d .8 .6 .8 (it turns out that I still got shimmy after replacing the ~28 mm Elk Passes with 42 mm Naches Passes, but that’s fine — I don’t ride no-hands a great deal), and I did discover right away that it seemed easier to keep on top of a gear as resistance — incline, wind — increased compared to the OS tubing of the ’03 — I didn’t get the feeling of “bogging down” as I increased torque to maintain speed. It’s a subtle feeling but I distinctly noticed the difference with the 2020 Matthews and I daresay this was due to “planing” tho’ I’ve still got all sorts of questions about that hypothesis. Still, I got thousands of wonderful miles out of the ’03 in its 3 incarnations: slick 1X10 gofast (46 X 11-21 10 speed with 26X1” Conti Grands Prix, fixed gear commuter with 26 X 1.25” Kojaks, via Dave Porter, as in the photo, and a later incarnation by Chauncey with f + rear custom racks, fender and rack bosses, and a tubular ss front fender support forward of the fork with provision for internal dynamo wiring and attaching Edeluxe I at the top.
