My Tikit has the large frame and since I'm at the lower end of the fit range my seatpost is has very little extension. This puts the saddle pretty close to the BB horizontally and I wanted to see how I'd like the riding position with the saddle moved back on its rails a bit more. To keep the cockpit roughly the same that required a shorter stem. I swapped the stock 100mm 15 deg rise stem out for a Salsa 80mm 15 deg rise unit. So far I like it. I'll report back after I get some longer rides. in.
