I don't know. I think I might be the only one that has a "ditch all spacers and HTFU" philosophy, but seriously just get rid of them and start riding. After a few rides you'll be totally used to it and it will feel normal. The way I see it these bikes weren't made to be used with spacers. They only include spacers for new riders that are coming off of hybrids or other types of bikes that put you in a more upright position. They also make riding easier for people with poor flexibility due to injury or people that have big bellies. IMHO spacers are just a crutch. The sooner you get rid of them the sooner you HTFU and get used to it. Why waste time by going 1 spacer at a time and have to repeatedly take off your stem and bars? If you feel otherwise and insist on using spacers, you should have purchased a "performance" aka endurance geometry road bike with a longer head tube that doesn't require the use of spacers. It kills me when I see bikes like the Roubaix with a stack of spacers on top of that. Yuck.
