Had a bit of a go on a Trek Remedy 8 2017 recently. The first obvious thing are the geometry changes from the earlier Remedy, is longer and slacker, but not too long and slack, mainstream conservative long and slack. I found the fit on the older Remedy a bit short.
In the high geometry mode it was quite nimble weaving through the trees on a twisty bit on single track, and acceptable on the descents.
Dropping it into low geometry and it certainly made a big difference to the bike, more than I would have expected based on the numbers. It was much more confidence inspiring on the descents, and felt a much more fun bike.
It climbed well, even in low mode, although did benefit from the mid/trail mode on the RT3 shock.
I’ve not ridden any SC bikes to compare it to.
