As Poseidon makes their frames, have you noticed any frame defects? On bike forum, one bike shop recently reported following: "Two newer Poseidons in the shop to be worked on last week and found that on both either the stems or frames are actually crooked. When seat tube is vertical (with a level) the right handlebar end on both are almost an inch lower than the left handlebar end. It is easy to see with the naked eye actually, but we took measurements from the floor up to show the customer the difference in bar-end height on the bikes. Either the head tube was welded crooked or the stems are defective."
As I am currently considering X Ambition, medium size, purchase, how does bike ride: either on top of bike or in the bike feel due to upright bike geometry? Due to 20" seat post and short top tube length, I am concerned rider (5'8" and 140 lbs.) will ride more upright position, on top of bike, instead of in the bike feel. Thanks
