I’ve had one for about 4 months now and love it. I have a steel hard tail that I use for flat xc stuff but four anything else I use the bolt. Mine is built with slx 1×9 and brakes along with flow rims and sektor coil fork.
Sounds like the perfect frame for what you want. With the lock out activated you can winch up most climbs but be aware that you can’t run a front mech so single ring is obligatory.
Being fit add and strong is definitely beneficial to get the most out of it as it is a little heavier than some depending on how you build it. That said, it is well balanced and assuredly composed on downhill sections. I don’t push it to anywhere near it’s limitations but I can’t see how you’d ever break it.
I have been using it for all my rides lately as I don’t mind about a slow painful uphill but if I was bothered about keeping up with my mates on an xc route the bolt probably wouldn’t be the bike to do it on.
