This is probably cheating BUT I’m going to bend the rules a bit.
If I were to get one bike to rule them all, I’d get the current Sworks stumpy.
12.84kg with chunky tires and the 34Grip2 fork. I would be happy to put it in trail mode with faster tires and I could race Leadville on it without really much hesitation or much extra time added.
Put the chunky tires back on, throw a 150mm Fox38 or Zeb on it, and really there isn’t anything that I’m going not hit on the bike at a bike park or any other feature. Anything big enough to where I need a bigger bike, I’m too old for that
