Sync. It’s the perfect bike for the peaks IMO – I’ve got a FF29 which I batter round the peaks regularly and the Sync is just the FF29 with all the improvements i’d make to it made! (slightly more compliant ride, bolt thru rear, slightly slacker HA) Each to their own, but i’ve broken too much carbon stuff to want to trust an expensive carbon frame in the peaks, bouncing rocks off the downtube.
It’s not going to be overly light frame wise though, i bet it gives away the best part of 500g to the carbon frames you mention. I guess it wouldn’t weigh a lot less than a solaris. My FF29 was 200g over what it should have been.
I bought the FF29 as a way of demoing a sync for a few months before splashing £1500 on a frame when i’d not tried a 29er, and i’m going to be upgrading it!
dropper post (stealth/covert) would be nice but not critical on a medium hardtail.
Dropper post option would be a must for me, i know the eddie is 31.6 but i’d be out on any frame that wouldn’t take a reverb.
