to me, (my opinion) I would travel up the road to Brechfa,,
I rode Afan a few weeks back, its definitley showing its age. Very worn and rocky (ready to smash your pedals) on the 6km Sheep track climb.. (which isnt too bad, just not much fun…)
Probably wouldnt bother with SPD’s.. Saw many many people failing when trying to clip in whilst trying to ride up a rock garden!
We ran the raven trail at Brechfa – and preferred it, was no where near as busy as the hyped Afan, which was nice..
I would say more technical, and had some nice bermed sections you could ride back round and hit again..
Some of the sections are gnarly! with danger of death signs.. Dont worry about em. Care obviously needed.
Have fun dude!
