There is only one, multiple award winning Ion K-Pact. With or without zipper. And now it's even on sale on some dealers. Maybe I'll get my third pair..
I have accepted the situation. Bought my bike at the height of covid prices. Realized then that I won't get much for it. Decided for some sweet upgrades instead of a new bike. Current bikes really do not offer anything ground breaking anyway.
Lets see how the market is in two years. Hopefully...
Depends where you ride. On the roads, probably not. But on trails if you spin-out your rear wheel against something hard, you'll loose studs. And spin-outs are easier on emtbs.
RC3 Zebs seem to have the opposite problem, hard to use all the travel and getting it to bottom out. At least 180-190mm RC3 Zebs are very progressive towards the end of travel.
