Road setup vs CX setup

How does a cx fit - cockpit length, bar height, seat height on cx compare to a road setup?

The cranks came as a short 170mm ? Road is 172.5 and climbing is 175. I think I'll leave as is for the moment.

I have a steel framed Ritchey Swiss Cross disc and a plastic-fantastic Cervelo R3. The Ritchey is a 59cm and the R3 is a 58cm. The differences between the two-- on paper-- are mere millimeters in most cases. The Swiss Cross shows it's CX nature with longer chainstays (+23mm) and wheelbase (+36mm), and a bit less BB drop (63mm vs. the R3's 69,5mm,) but stuff like reach and stack, trail and rake, ST║... the same. That said, they feel very different when ridden. There's a total of 1║ difference in HT║, and I just can't imagine that alone would be the reason. Both bikes have 110mm stems, identical bars, 175mm cranks, the same pedals, and still somehow exhibit utterly dissimilar behaviors. They turn in differently. They descend differently.

So I would say don't go by paper. Start with the frame/bike that is close to your "road" bike and adjust accordingly.

Thank you. I have the bikes now. Junior has one in CO, I have the other in CA and configuring for when we meet at MTB Collegiate nationals in Missoula, MT - Oct 18. Both frames are very close. One came with Both will be more upright than the road bike, which is very low.

I expect to replace some stuff always. Bar/stem, seat, maybe post, tape, cables. One bike has 170mm, the other 175mm cranks - so something needs tweaking there. Just, I'm going to see how it goes before buying more stuff.

The difference between my road bike and my CX bike is bascially just the stem length and handle bar height. I like my stem to be about 20MM shorter. My road bike also has the 6 degree stem flipped down where my CX bike has the 6 degree stem flipped up. Basically, I like to be a little more up right on the CX Bike. I dont know if that is the "right" way to do things, but it feels like I have more control on the CX bike that way. Also, being super aero usually isnt a real big deal on the CX course.

I use the Same bike for both.

For road this past year, I used a 110mm 10' flipped down.

For cx season, I switched to a 90mm 7'stem flipped up...and just left it that way even for road riding.

the major difference is in hood optimization. 99% of the riding will be done on the hoods with very little time in the drops https://www.cxmagazine.com/mechanica...better-control

I moved the hoods up 3X today. Still maybe too low.

Identical reach, but I run a -6 stem for CX and a -17 on the road. I also run my bars/hoods tilted up slightly on the cross bike bike vs having them level on the road bike. Seems to work well.
