I am thinking about getting a Eddy Team SC frame. Anyone know the stand over height for a 48cm frame?

If you are going to spend the money an a great frame such as the Merckx Team SC, you should do yourself a favor and get a professional fitting done. Stand-over height is only one aspect to fitting, but there are other issues involved.

My advise would be to go to a LBS who can do a fitting, or take a look at the link below to Colorado Cyclist's guide to fitting. They also sell the Team SC, so they can give good advise as to whether or not the frame is a good fit for you.

Here is a Merckx geometry chart for you to look at:

His frames have always been built in the traditional style of geometry with long top tubes and relaxed seat tube angles. His frames fit me to a tee, but there are others who do not fit this geometry so well.

Top tube lenght is more important.

So if my privates are pressed against the top tube while I'm standing and the top tube length 'fits' then it's ok?

Standover clearance on a small frame should be in the range of 2-4cm to hard contact in bare feet. Another good indicator of proper vertical frame size is the the saddle height above the top tube. 16-18cm is a good range for a small frame. Larger riders may able to get by with more, if they can tolerate a bar to saddle height difference of more than 10cm.

Those that over-emphasize top tube length rarely pay attention to the fact that TT length typically changes half as much as frame size. In other wrods, it's common to increase the TT length by 1cm, while frame size is increased by 2cm. Looking at TT length only can be worse than only looking at frame size. If your body proportioning is odd, then TT length could be more critical.

Frame size also affects the head tube length and the saddle to bar height. If you pick a frame that's too small, you'll end up with a large stack of spacers and/or a high rise stem to make up for the vertical sizing error. I see lots of pics on this site of that situation.
