I had a large (I’m 6ft2 and sexy as foook), tbh the large was too small.
I know rock a 57 Ritchey Logic 2.0 and its superior in every way possible.
I know the PlanetX has sold shedloads and its popular. It’d make a great commuter but for a smidge more money there is soo much more (better choice out there). I was dazzled by the groupset that came on the PX.
Frame/forks first then groupo. Wheels of course make a huge difference.
Not sure what wheels come on the current PX but my FSA ones are still in the shed. Relatively cheap Ultegra wheels were night and day compared to those.
ALL IMO but look at Paulscycles etc first.
