I just sold a Planet X Pro Carbon to build up a Singular Gryphon. 50-34 by 11-36 gearing, Hope V-twins and drop bars. Currently running 2″ Big Apple slick(ish) tyres.
Takes a while to spin up but once it’s going not much slower that the carbon road bike and laughs at pot holes.
Next mod will be some OpenPros on Hope Pro IIs so I can have one set of 23-28mm slick for it and one set of 2-2.4″ knobblies.
Not a road bike, not a cross bike, not really a mountain bike. Bit of everything and goes most places on or off road (muddy off road corners are fun on slicks) – lots of fun.
