Have had a look at the Radon bikes. Like you, I was about to pull the trigger on a Canyon 29er hardtail.
The Radon bikes seem slightly better specced than the equivalent price Canyon BUT the thing that’s causing me a little concern is the geometry, specifically the head and seat angles.
For the sizes I’m looking at (M – 17.5″ in the Canyon or 18″ Radon) the difference is this:
Seat angle – canyon = 74deg radon = 73deg
Head angle – canyon = 70deg radon = 71deg
My last bike had a 71deg head angle – good on the climbs and flats but a little fear-inducing when the terrain points downhill. The slightly slacker HA on the canyon should help it play more nicely on the descents.
I still haven’t finally decided though. Dammit.
