Richie, we have riders at 5'6" to 5'10" who are reporting the 14" to be good for them. Our feedback is that the 12" was just not high enough, but we can cut one for your needs. Don't forget, ours are polycarbonate and will not shatter or break. Tinted or clear and vented or non-vented available. We will get you comfy on that bike, and do it for 15% off and free shipping this month!
