I have done something similar with a bike I own. Not a Riv, but also has relatively low bb height. It is a bike originally designed for 650b rim brake wheels. I had the cantilever posts moved so I could use 26" wheels instead. I just really wanted a 26" allrounder, road geo and spritely tubing. It turned out well and scratched an itch. Where I live, 26" rim brake wheels are much easier/cheaper to source so it offered that advantage too.
Moving the canti posts is invasive work. On my bike the originals were Tig welded, so needed cutting off. The replacement posts are brazed on. The paint had to be sacrificed in the the area of the brake posts, of course. I touched up with primer and a contrasting top coat. It came out nicely enough and I'm pleased with my 26r. If you did this mod to your Appa, you'd be able to switch between 700c and 650b using the Motolites. Generally, I don't think you'd improve the bike or achieve much else than scratching an itch. I do NOT discourage you in this! IanA alberta canada -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
