I am having difficulty getting my handle bars up close to level with the seat. I have tried a 63 cm diamond type frame and this gets the bar up level with the seat but I have absolutely zero standover clearance. I have a 58 cm diamond type frame and have adequate standover clearance but the bar is at least 5 cm below the seat height. This is on a road bike. So can I get a mountain bike quil that will raise the bars? All the road bike quils even the nitto seem too short to make the correct adjustment. Maybe I need to go with a compact frame design to get around this problem. I am 6 feet tall and have an inseam of 87 cm so what is going on. I can only guess that the diamond frame is not to built to get the bars level with the seat for most riders.
