They’re great – rather than having a 6″ susser and an XC bike I’ve downsized to just the c456.
Light, comfy, great angles and uber fun to ride.
I reckon it’s slack enough without a works components headset.
On-one do the Smothie Mix Taper which I’ve had no problems with but many prefer the Hope Mix’n’Match way to go – only a tenner between them.
Front mech is very standard – the SLX one from my Reign fits perfectly.
Seat tube is quite relaxed so an in-line post for tall riders.
And, there’s not that much difference in the reach between the 16″, 18″ and 20″.
I’m running 120-160mm Wotans. Gnarrrr!
