I'm torn between those 3 carbon bikes for enduro/am riding. Nomad is for sure the most posh bike. Capra should ride as well as Nomad if you belive all the raving reviews about it in Europe. The quality of the frame might be lower but I wouldn't need to drop my pants as low as for the Nomad to afford it. Financial wise the Altitude sits somewhere in between and I'll be able to get quite a good deal on it. The geo of the Altitude appears to me somehow old fashioned. Anyway, who rides Rocky Mountains these days yet, the dream bike maker of my long passed youth?
Any advice would be deeply appreciated, especially from people who were able to ride at least two of the above mentioned bikes.
