i’ve got a short torso, and long legs, and a long 20″ frame; i can get away with a 35mm stem (an el guapo).
i wouldn’t say that there’s a massive difference in ‘feel’ between my 35mm stem, and the 50mm / 70mm stems that preceded it.
ok, some difference, but not massive – and it’s not better, or worse, just different.
the best thing, is that the bike fits me better know.
in other words, the 15mm difference from the 50mm, made a bigger difference to my position on the bike than it did to the way the steering felt.
yes try a 35mm stem, but for exactly the same reason why should also try a 60/70/80mm stem.
