Specialized M4 Cross frame(9 posts)

I am getting one of these and noticed that the 56cm frame has a 57cm top tube (nice fit for me) but an 84cm standover height. Wow, that's 2 cm more than my current road bike which is a 58cm frame with a 58cm top tube. The 54cm CX frame has a standover of 82cm which is exactly the same as my road bike but only a 56cm top tube.

Has anybody ridden one of these and notices that the standover is really that big? I know the BB is higher but I need to be able to get on and off this sucker without feeling like I'm jumping up on to a frame for a giant person.

I'm probably going for the 54 and a slightly longer stem just because the standover is decent for re-mounts etc.

Remember - 'cross bike standover is measured using 'cross tires.

I'd go with a size similar to your road bike; you might "notice" the difference but it won't make any difference in practice. I only notice the taller standover during the transition from road season to 'cross season; once the 'Lugi becomes my main ride, I don't notice it at all.

yes it is measured with cross tires, and I will have 'cross tires on it. My road bike is a 58cm with a 82cm S/O height. The 58cm CX frame has a 86cm S/O height, this is way too big for me. The 56cm frame is closer to my proper size and maybe the S/O height won't be an issue with the higher BB etc. but it sure looks BIG.

What makes the stand-over so high, the long Headtube, or is the toptube welded to the top of the seattube? Mountainbikers allready for the solution : sloping top-tubes. But then again, they never try shouldering the bike under the top-tube...
Anyone ever seen a crossframe with bended top-tube, to get the best of woth worlds? Would be ideal I guess...

I think it's the BB height that makes it so high, the frame looks to have a horizontal TT from the picture. All else being equal, a higher BB and a 56 ST makes a higher standover height than a regular 56cm road frame. The HT should be made to fit the other dimensions (so I would think), and give enough clearance for fork/wheels/tires etc.

If it was me I would go with the smaller frame. As I stated before I like a little more upright ride on my cross bike, just feel more solid that way. The races here in socal are more MTB oriented, not a true euro style cross. I also use my cross bike for a lot of singletrack so you might take that into account if you plan to ride a lot offroad. Length you can work with, standover is non-adjustable

Climbo, don't make a the mistake a friend of mine made, go with the 54, he rode a 58, has 32 to 33 inch inseam and went with 56, when it came cross season he imediatley realized he had too big a frame. I would definately go with the 54. I ride a 58 rb and ride a 54 IF cross bike.

I am 6' 0" with a 87.5cm (34.5") standover height measured on the floor with no shoes. My road bike has a 33" SO height and the 56cm frame will have exactly the same. My old 'cross/fixed gear bike had a SO height only 1.5 cm less than this so I am leaning toward the 56cm M$ just so that my TT is not so short. I prefer the 57cm TT to the 56 has I already run a 13-14cm stem on my bikes now. I hate making this call without riding the bike first but I can get it so cheap if I have to suffer for a year I can probably trade it next year.
