I went to 2alps and alp dhuez last year running a pair of Maxxis HR2’s 3C up front and dual compound on rear, both dual ply – zero punctures for me.
As has already been said, fixing punctures is no fun and its very rocky at the top of alp dhuez and parts of 2alps.
I run Magic mary and rock razor in the UK for trails. Defo wouldnt run that combo at 2alps. The rock razor isn’t the best tyre for slowing down. Possibly would run the MM up front in the trailstar (or vertstar) compound will get pretty worn on the shoulder knobs as theyre a bit softer than the maxxis. And as its a pretty similar tyre to the Minion DHF I’d probably go for that instead.
Also, the one thing that stood out was the locals and nearly everyone else ran maxxis at 2alps. Other tyre brands were very scarce.
