Came from a helius AC to a Geometron G16 in 29er with a fairly modest build, no carbon anywhere, hope fortus 26 with 2.35 tyres.
I loved the helius and it climbed well and descended a bit better but the G16 is better in all areas. Climbs better, loads more grip on the back end and no wandering front end.
Composed and stable descending, doesn’t get hung up in tight knacky tech just needs a bit more muscle and a bit of thought to body position to get through tight slow corners.
I’m a couple of months into riding it and still tweaking the shock setup etc but no regrets. It’s my first 29er too and not looked back.
