It’s also interesting that nobody seems to like the idea of starting with a “small” bike and progressing to “bigger” bikes as your skills develop.
That’s exactly what I’m doing, started on an entry level hardtail, upgraded forks, brakes, chainset etc. as I went Those parts are now on a 120mm fs frame, finishing the build tonight. It’s worked perfectly for me and genuinely felt like I was ready to make a step up.
Don’t imagine I will ever go much bigger than 140mm or so though, something like a Norco Sight, anything above that it’s going to be too geared towards the downs and stop me enjoying the ups as much (I think). That will come in many years and is way down the list behind some skills days and so on.
Sounds like skills are where you need to look, maybe there’s something you can do to the bike config in the mean time to make it feel more ‘right’ for your riding though?
