@njee20 – you need to read what I wrote. I stated that my Solaris had Hope wheels and Bontrager tyres, I didn’t say it was light. 😉
Yes, there are options to make it lighter but there’s two caveats – price and the fact that I’m not exactly flyweight. 😳
What you said was “there’s not a lot of options to make it any lighter”, which is totally untrue (and implied to me you think what you have is light), literally every single component could be upgraded to save weight, in some cases easily. You don’t think those upgrades are worthwhile, and that’s fine, it’s totally diminishing returns, but wading into a weight weenie post with your XT groupset, Bontrager tyres and 21lb bikes being as light as you can go!? That’s heresy! 😉
Anything with a Lefty is definitely a good place to look second hand, they’re significantly lighter than conventional forks. A second hand carbon F29 is probably within budget.
