sas78- I’m 6’2″ with an inside leg of around 36″… so quite leggy. Run my saddle around 82cm from centre of bb to top of saddle, was stuck between the L and XL, the XL was the right choice for an XC bike. One days commuting so far and been impressed, didn’t take much longer than on my old commuting bike with 34mm tyres. Don’t feel perched on top, more part of the bike.
So far couple of issues.
The brakes are w**k, they weren’t set up properly out of the box, but after a proper setup they just don’t work properly.
The stack height on the front is pretty high. Removed the 20mm or so of spacers, flipped the stem and ordered some flat bars. But would still prefer a lower front (emailed Cannondale to see if there’s a replacement for the 25mm headset cone).
However, for £420 delivered to your door, it’s never going to be perfect with top quality parts. But I reckon the frame/forks are prime for upgrading if you want, but if not you’ve still got a decent bike (maybe apart from the brakes).
