I had a Vitus Energie bike from last year and loved it although I wasn’t sold on the Apex 1. I did a muddy CX race with it and managed to drop the chain. I wasn’t the only one with Apex 1 who dropped a chain that day either. If I was buying one again I’d go for the Rival purely for the weight. Also another thing to consider is it’s pretty difficult to get different chainrings for the Apex 1 four arm cranks. Much easier to get the 5 bolt ones of Rival.
