Except for the color (white) I'm ok with my adjustable stem on my Felt F75. It's the kind of stem that has a plastic sleeve inside of the stem that, after removing the stem from the steerer, can be rotated to either 14 or 10 degree angle. After buying the bike last July (after 13 yrs off of the road bike) 14 degrees felt great. I've found no problems riding with this type of adjustable stem. Just last week I adjusted it to 10 degrees, after allowing my back, neck, shoulders 6 months to get used to the road position. 10 degrees now feel great. Some day, I'll probably change it out for a fixed 10 degree stem in black or silver.
