Ram: 2 degrees of TT upslope Sam: 6 degrees of TT upslope At that frame size, every one degree adds 1 cm of head tube height. So on paper, the handlebar height of a 60 cm Sam is about the same as a 64 cm Ram.
The "new" sizing regime of Rivs with the 6 degrees of TT upslope was new around when the Sams were introduced, maybe 13 years ago? Bombadil was also the new bike bike around that time that pioneered the new greater TT angle. Before that, the models tended to be around 2 degrees. Ram was never made again after the "expanded" frame geometry was unleashed, so Rams are all 2 degrees. (AHH's, on the other hand, have come in both styles, depending on when made. And logic says the same is true of Atlantis, although in the old days, the Atlantis was a wild one with 2.5 degrees (!) of TT upslope. For AHH and Atlantis, the switch to Made In Taiwan is also the switch from low angle to high angle.) On Mon, May 24, 2021 at 8:13 AM James Warren <jimmacwar...@gmail.com> wrote: > Eric is right.
