2008 Cannondale Rush SL frame. Handmade in the USA. 18.5 from the centre of the bottom bracket to the top of the seat tube. Can take pretty much any size of steerer with right headset fitted. In excellent condition for the age with the odd cable rub and stone chip to be expected, there is some paint bubbling on rear triangle. Please see all pictures to satisfy yourself of the overall condition. Believe the rear end gives 110mm travel and is suspension correct for a fork with the same travel. No issues with bearings, BB threads etc.. And no cracks or dents. Looks like this has not had a hard life at all. For 26 wheels with standard 135mm wide drop out.
