The Sabre-2 is an Integrated Seat Mast high performance road bike.
It can be built mild or wild with tubing selections from Columbus, True Temper, Kaisei or Reynolds. But one thing always remains constant, the Custom Drawn for Don Walker Cycles, Reynolds seattube. It was drawn in 631 and butted specifically for using as an integrated seat mast. Unlike other brands who use seat mast “toppers,” or an external post, I use an internal post with a seat collar. I do this for a few reasons: one, it can be very easily replaced at any local bike shop should it ever fail, and two, if you ever decide to sell your bike, the seat tube can always be cut down to accommodate the new owner.
