Yeah, they’re good frames at a good price and well deserving of some future upgrades.
I had mine out for between 4 and 5 hours on some extremely muddy singletrack with plenty of roots, rocks, sand and general trail debris looking to see if I could find anything that was crying out for an upgrade (I have birthday money to burn). Despite the bike being thick with mud and taking the odd knock here and there, there was nothing on there that I thought needed immediate replacing.
The tyres are good enough and fast rolling enough to last me until summer at which point I may go for something lighter, the brakes have been solid and silent (even when covered in mud) and have caused me far less problems than the Elixir 5’s on my last bike did. Despite wanting to upgrade to XT, the Altus gear is doing a surprisingly good job, and I would feel guilty ripping it off the bike just for the sake of it, so I think I will wait until it’s worn out before replacing it. Heck, even the saddle was comfy enough for me.
The frame is definitely a highlight though, the geometry is spot on for me and my riding style.
