Looking for advice about these bikes. I can get a good deal from my LBS on either bike, the spark 910 or the CC X01 tallboy. I am coming off of a Niner Jet 9 RDO. The geometry is more or less similar on the spark and tallboy. I have ridden the tallboy and love the way it climbs. I haven’t had a chance to ride the spark and would like an opinion. I will be primarily being riding XC marathon races like Oramm and Fools gold with occasional trips to pisgah. I am looking for a “quiver of one” bike.
