ive ridden both these bikes i had a stiffee for about 3 yrs and road the ragley on 2 2/3 hr test rides
the cove is a great all rounder great in single track ,fork at 120mm,
took it to cwm carn upliftday great, flat pedals , fork at 140
great at jumping and play riding
great at trail centers,its biggest weakness is climbing and i wouldnt want to race it,but with an adjustable fork it can do most things well,
the ragley is a great all rounder to but i didnt feel the need to adjust the fork as much as the stiffee and it climbs alot better than the stiffee,
it felt like i could (and did) drop me elbows and hammer climbs and flat stuff better than the stiffee,
i didnt really test it out on many jumps so cant say anything there
i had sold my cove and was close to getting the ragley but on the 2nd test ride i coulnt help notice how harsh the back end was over rough rooty stuff and it put me of,ive ridden and own alot of hartails so it wasnt just me not being used to it,im still thinking about the blue pig which i think will be the best option or i might save for the ti one.
if your more on the side of freeride,play riding the cove is slightly better but expensive,but if your more a bit of everything xc based one of the ragleys is the way to go,i really need to test ride a blue pig
