I too have had a large 2015 (27.5 wheels) buit from ground up to my spec with
pikes / flow-hope / bergtech / sram / reverb / Invisiframe etc
It still looks new .it’s been great bike and the frame is built very well white some thoutht from obrea . It’s still on the original bearings with no sign of play ( never had a bike that’s done that before )
One of the best bikes I’ve owned
it’s now time to sell it on as i have bought a ebike 🤦🏻♂️
