what is versatile about the Felt IA 16? It's a narrow-tall bike with a high stack proprietary stem and a high stack proprietary aerobar system.
I had a quick look, and the pad stack adjustments are roughly 60mm for the felt, vs 90 in the canyon. reach for the pads was similar, but i am aware the stock extensions are a bit short for larger frame sizes. I was planning on a tri rig alpha one front end.
I know the iax are lower than the ia. I could not find standover numbers for the speedmax, but it looks lower. However, the speedmax bento box seems to add a lot of height to the speedmax.
